Approved SIMM List

The following tables list SIMMs that are known to be compatible with the Premiere/PCI Expandable Desktop. SIMMs that are not listed also should function properly as long as their specifications are compatible with the devices listed below. In general, SIMM devices that are faster than those specified for a given platform will work although no extra performance will be realized.  The SIMM devices shown are categorized according to three levels of qualification:

1. Intel Approved and Tested:  The device has been electrically tested by Intel and is known to be compatible with the Premiere/PCI Expandable Desktop. In addition, the vendor has met or exceeded Intel's product change, quality control, and availability requirements and is listed on our Approved Manufacturing List.

2. Intel Tested: The device has been electrically tested by Intel  at ambient temperatures; running a series of Intel tests (PCDIAG) and applications.

3. Customer Tested: The device has been electrically tested by a customer and is reported to be compatible with the specified platform(s).

Intel recommends that SIMMs listed as (1) Intel Approved and Tested or (2) Intel Tested be used to ensure reliable system operation. SIMMs not listed or listed as (3) Customer Tested can be used; but, in the event of unreliable system operation, the SIMMs should be replaced with SIMMs tested by Intel (1 or 2) to determine whether the SIMMs are causing the problem.

IMPORTANT NOTE

SIMM devices with gold contacts should NOT be placed into SIMM sockets with tin-lead contacts or vice-versa. Mixing dissimilar metal contact types has been shown to result in unreliable memory operation. For more information, see FaxBack document 4229.

Telphone numbers are provided for your convenience.  These were accurate as of July 1994, but may change at any time without notice.

Errata

Power Supply Voltage Ramp Requirement

DOS Mode Command doesn't support 19,200


Power Supply Voltage Ramp Requirement

Intel has recently become aware of a functional limitation with the non-voltage regulated versions of the Premiere/PCI Expandable Desktop. This limitation only affects product codes BP5E60AT050, BP5E60AT850, BP5D60AT050, and BP5D60AT850.

Symptom

Among the group of product codes listed above, we have noticed a very small number of systems will freeze during power-up prior to POST.  Sometimes resetting the system corrects the problem.

Cause

When turning system power on, some power supplies do not reach 4 volts Vcc within 5 milliseconds.  Because of this, the system cannot always synchronize its clock and may cause a "hanging" condition at boot.  In order for the board to function properly, the power supply must provide 4 volts Vcc within 5 ms of power on.

Design Consideration

Power supplies should be tested and validated to rise to 4 volts within 5 ms.  We have seen no failures when this specification is met.  Power supplies rising to 4 volts after 25 ms have exhibited a fallout of 3-4%. The gray area, where power supplies rise to 4 volts between 5 ms and 25 ms, may show signs of failure however we have no statistical data.  The speed at which a power supply ramps up is not a widely published specification so you must test your supply to be certain of the ramp speed.

This functional requirement will be corrected in a new version of the fab scheduled to be available in Q1'95.


DOS Mode Command doesn't support 19,200

The DOS MODE command for setting the serial ports to 19,200 baud is not supported by any of the BIOS versions.

   mode com1: baud=19200

will return a "Command not supported" error.


Product Description

The Premiere/PCI Expandable Desktop actually consists of two separate product lines, an older 60 MHz only product (internal code name Batman), and a more recent design that can be configured to support a 66 MHz clock frequency as well as a 60  MHz clock frequency.  Also, different chassis are used at the system level.  For more information, see the Product Feature Changes sectionProduct Feature Changes .

Intel Product Update Bulletin - Board History   (66MHz Batman Revenge) - LBX clock jitter fix, June '94
LBX clock jitter fix, June '94

TL432 component at U6H1 can enter oscillation due to incorrect load capacitance.  This oscillation causes increased clock jitter on HCLK signal of U6G1.  This increased jitter causes the LBX circuitry to excessively compensate which results in heating of LBX and eventual failure to maintain clock sync.  Capacitor C6F2 must be installed to insure that load capacitance is within stable operating range of the TL431 component.

New Pentium processor heatsink bonding process, March '95

The heatsinks on Pentium processors installed on boards will no longer be adhesively bonded to the processor. Thermal grease will be used instead of an adhesive to provide a thermal interface between the heatsink and the processor. The heatsink will be kept in place mechanically by the recently implemented clip and tabbed socket changes, as listed in previous ECO notifications. Also, a new clip will be added as the preferred part, the old clip will change to alternate.

AA 620004 and 620006 will change from -008 to -010. This is a documentation change only to bring the dash numbers back into sync with the other AA numbers. These changes are being implemented to improve manufacturability. This ECO affects only 66 MHz products; a previous ECO updated the 60 MHz products.

New Fab, April '95
New Fab, April '95A new fab that incorporates rework, improves signal quality, and improves manufacturability will cut into production in the Q1 '95 time frame. The details of this fab change are listed below.

Requirements/Limitations on FAB Spin: Not have to resubmit for FCC (just verify); NO FORM, FIT, FUNCTION Change, No suitcase jumpers move, No slots change, No connectors change, No physical height change, Systems configuration label does not change, Do not move test points.

List of DESIGN fixes/incorporations into new fab:

Add voltage reference circuit to correct problem with power supplies that have a very slow Vcc ramp time.

Add capacitor sites (120pf) for possible signal quality improvement on the following signals:  DACK0-7, EOP(TC), BALE, DEV-SEL, INT, NMI, RESETDRV

Widen VREG trace to improve current capacity and reduce voltage drop.  12 mil sense trace widened to 25 mils.  Doubled 75mil trace with gnd plane cutout.  Added wide trace on primary side to double trace width.

Change CAS trace topology in SIMM sockets to remove diodes and improve signal quality.  Do split routing out of PCMC for CAS traces to SIMM banks but keep diode sites.  Trace length equal to within .1 inch for CAS traces to SIMM sockets from PCMC. Will add zero ohm resistors to allow use of diodes if matched trace length strategy does not work.

Improve signal quality of PCMC CAA3-by adding sites for overshoot clipping diodes.

Remove nets to PCIINT pal (U5A1) but leave site and add test points to each node in case used in future for fix.

List of MANUFACTURING fixes for new FAB:

Move trace routing from around plated through holes to reduct solder bridging.

Change SIMM socket tooling hole size to improve manufacturability. This does not allow for retention, but does prevent reverse installation. Unplated; .096+/-.003, .070+/-.003, .070+/-.003.

Move bypass cap C4C2 to eliminate interference with CPU clip. Moved C4C2 to new location C4B3.

Change PCI connector tooling hole sizes to provide retention:  Unplated; .099" +0.002/-0.001.

New SMC37C665GT Stepping and Keyboard Controller F/W, May '95late Q1

The SMC GT I/O controller is moving to an E stepping, which  uses a new fab process and is changing from an epitaxial substrata to a non-epitaxial substrata. Non epi or bulk silicon has the same resistivity throughout  no layer has any differing resistivity. The bulk resistivity is tailored to give the transistor characteristics required for the product and design performance. Specific part number changes will be listed in future ECO notifications.

The keyboard controller F/W update is a routine code maintenance release which keeps the code in sync with other Multikey/42 firmware versions offered by Phoenix. The 8242PC will change from v1.29 to v1.38. An Intel FPO number will be marked on all product to improve traceability and a firmware version indicator will be added to the part mark.

The ESD anti-static bag will also be changed slightly to improve the manufacturing process.

List of Firmware Changes:

Firmware Optimized for 12 MHz: Default timings were changed to optimize device performance at 12 MHz.  Several customers have requested this change as most systems, regardless of CPU clock speed, now use the keyboard controller at 12 MHz. The option still exists for designers to optimize the keyboard for use at other clock speeds through the option file settings.

High Capacitance Keyboard Changes: There are keyboards in the market place with high capacitance on the Clock and Data lines.  These keyboards did not respond fast enough to pass the old POST routines.  Based on customer requests, changes were made to the firmware to allow for use with these keyboards.

Double reading of Port 1 implemented to provide time to detect the change in P1.0.

Minimum interface inactive time was extended from 60 to 100 s for each clock switch.

Minimum interface inactive time was inserted in Abort.RcvXmt routine.

The Clock line is now checked first in A9h (Test Aux. Device) command, allowing Novell's UPS driver to work with the Mouse Port.

In an AT environment, when Password was enabled but the Override bit in KCCB was set, the ChkPassword routine would corrupt ScanCodes that matched Password.  To fix this, an additional checkpoint for the Override bit is inserted in the ChkPassword routine.

All polling loops were rewritten in order extract common parts and organize them as independent routines.  Four new routines were derived: Aux.Start and Kbd.Start process respective device start bits, Kbc.Cmd and Kbd.Cmd process controller and keyboard commands respectively.

A more condensed method of imbedding the Revision Number is used, copied from Multikey/42G (firmware for 82C42PE device).

After a GA20 command is detected, the firmware first checks for KBD and AUX device start bits, and only then for GA20 data.  This prevents the keyboard controller from missing start bits under GA20 attack.

Security: All mouse and keyboard commands are now blocked when security is enabled.  Security can be enabled by either Keylock or Password.

8242PC  Part Marking History

Intel Product Update Bulletin - Board History   (66MHz Batman Revenge) - LBX Power On Lockup Fix, May '95
LBX Power On Lockup Fix, May '95late Q195

It was discovered that the Premiere/PCI ED baseboard would occaisionally hang during power up when used with certain power supplies.  Intel components discovered an anomaly associated with the powering-up sequence of the digital portion versus the PLL analog portion of the LBX chips.  The anomaly showed itself as a lock-up or hang condition within the PLL circuit.  This lock-up prevented the system clock from operating within the digital portion of the LBX, which caused the system not to start at power up.  By tying the two sources, VDD and PLLVDD, together the digital and analog portions of the LBX power up simultaneously and LBX lock-ups are avoided.  To connect the sources together, the following circuit components changes are required:

1)  Remove components R1E4, R1E8, U1E1 and R1E6.

2)  Replace R1E5 with a 10 ohm 1/8W resistor.

3)  Run a wire from  R1E5 pin 2 to a large VIA below R1E3 silk screen.

Boards with the old AA and PBA numbers listed below that are also marked with QAN# OR2374 have also been reworked to correct the problem.

Intel Product Update Bulletin - Board History   (60MHz Batman Revenge) - LBX clock jitter fix, June '94
LBX clock jitter fix, June '94

TL432 component at U6H1 can enter oscillation due to incorrect load capacitance.  This oscillation causes increased clock jitter on HCLK signal of U6G1.  This increased jitter causes the LBX circuitry to excessively compensate which results in heating of LBX and eventual failure to maintain clock sync.  Capacitor C6F2 must be installed to insure that load capacitance is within stable operating range of the TL431 component.

BIOS 1.00.09.AF2, Diode Changes, and LBX S-Spec. change, October '94

A new BIOS (Ver. 1.00.09.AF2) that supports the Plug and Play standard is planned to be available in the September timeframe. This BIOS will implement several changes that will be visible to the end user, including an entirely new CMOS SETUP routine and removing the ISA IDE DMA option. The anticipated changes implemented in the Phase II BIOS are attached.

The RS232 diodes (CR12F2, CR12F3) have been changed to a functionally equivalent part to relieve an availability shortage.

The 82433 LBX components (U4E1, U6D1) have changed to a more robust S-Spec, and two resistors (R5D2, R6D20 that help determine the VCO gain have changed value from 2.7K ohms to 2.2K ohms to improve the phase lock loop tracking.

Changes to accomodate power supplies with slow ramp times, Feb. '95

Eight resistors, a transistor, a linear IC and one rework wire will be added to the board to compensate for power supplies with slow ramp times. Specific part changes are:  TL431A added to UllH2; transistor added to Q12H1, 2K resistor added to R11J3; 3.01K resistor added to R12H1; three 0 ohm resistors added to R11J1,R11J2,R12H4; 330 ohm resistor added to R12H5; 2K resistor added to R12H3; 1K resistor added to R12H2. VCO-60 LBX part added to BOM as an alternate.

Slow ramping power supplies allow a clock signal to be present at the LBX components before the Vcc voltage has reached approximately 4V. As a result, the phase-locked loop circuitry may not lock correctly, causing the board to hang during power up. This situation has been aggravated by using a newer version of the LBX component with a faster PLL circuit. This rework holds off power to the clock chip until the voltage has reached a valid level.

This change affects only product codes BP5D60AT050, BP5D60AT850, BP5E60AT050, and BP5E60AT850 (60 MHz boards).

New Pentium processor heatsink bonding process, Mar. '95

The heatsinks on Pentium processors installed on boards will no longer be adhesively bonded to the processor. Thermal grease will be used instead of an adhesive to provide a thermal interface between the heatsink and the processor. The heatsink will be kept in place mechanically by the recently implemented clip and tabbed socket changes, as listed in previous ECO notifications. Also, a new clip will be added as the preferred part, the old clip will change to alternate.

AA 624440 and 624437 will change from -006 to -008. This is a documentation change only to bring the dash numbers back into sync with the other AA numbers.

These changes are being implemented to improve manufacturability. This ECO affects only the 60 MHz products; a separate ECO will update the 66 MHz products.

New Fab, Apr. '95

A new fab that incorporates rework, improves signal quality, and improves manufacturability will cut into production in the Q1 '95 time frame. The details of this fab change are listed below.

Requirements/Limitations on FAB Spin: Not have to resubmit for FCC (just verify); NO FORM, FIT, FUNCTION Change, No suitcase jumpers move, No slots change, No connectors change, No physical height change, Systems configuration label does not change, Do not move test points.

List of DESIGN fixes/incorporations into new fab:

Add voltage reference circuit to correct problem with power supplies that have a very slow Vcc ramp time.

Add capacitor sites (120pf) for possible signal quality improvement on the following signals:  DACK0-7, EOP(TC), BALE, DEV-SEL, INT, NMI, RESETDRV

Widen VREG trace to improve current capacity and reduce voltage drop.  12 mil sense trace widened to 25 mils.  Doubled 75mil trace with gnd plane cutout.  Added wide trace on primary side to double trace width.

Change CAS trace topology in SIMM sockets to remove diodes and improve signal quality.  Do split routing out of PCMC for CAS traces to SIMM banks but keep diode sites.  Trace length equal to within .1 inch for CAS traces to SIMM sockets from PCMC. Will add zero ohm resistors to allow use of diodes if matched trace length strategy does not work.

Improve signal quality of PCMC CAA3-by adding sites for overshoot clipping diodes.

Remove nets to PCIINT pal (U5A1) but leave site and add test points to each node in case used in future for fix.

List of MANUFACTURING fixes for new FAB:

Move trace routing from around plated through holes to reduct solder bridging.

Change SIMM socket tooling hole size to improve manufacturability. This does not allow for retention, but does prevent reverse installation. Unplated; .096+/-.003, .070+/-.003, .070+/-.003.

Move bypass cap C4C2 to eliminate interference with CPU clip. Moved C4C2 to new location C4B3.

Change PCI connector tooling hole sizes to provide retention:  Unplated; .099" +0.002/-0.001.

New SMC37C665GT Stepping and Keyboard Controller F/W,  May '95

The SMC GT I/O controller is moving to an E stepping, which  uses a new fab process and is changing from an epitaxial sub-strata to a non epitaxial sub-strata. Non epi or bulk silicon has the same resistivity throughout  no layer has any differing resistivity. The bulk resistivity is tailored to give the transistor characteristics required for the product and design performance. Specific part number changes will be listed in future ECO notifications.

The keyboard controller F/W update is a routine code maintenance release which keeps the code in sync with other Multikey/42 firmware versions offered by Phoenix. The 8242PC will change from v1.29 to v1.38. An Intel FPO number will be marked on all product to improve traceability and a firmware version indicator will be added to the part mark. Please see the attached Release Notes for complete change details and benefits.

The ESD anti-static bag will also be changed slightly to improve the manufacturing process.

1.00.07.AF2, May '94

Features Fixed in this Release

Changed PCI Read & Write routines to perform a single 32 bit I/O operation.  Thus, removed the EMM386.EXE fix.  Done since EMM386.EXE is fixed and want to perform a single 32 bit I/O operation to PCI Config Space (as opposed to two 16 bit I/O operations which is a less efficient method of accomplishing the same goal).  This also allows the Cirrus PCI video chip to function properly since it only functions properly with 32 bit I/O to its PCI Config Space.

Language Support

Beta 9.01

o	Multi-language support is now available.

o	OEMs and users will be able to flash language sets into the BIOS and configure which language is used through Setup.  The current plan is for language pairs consisting of: English(US)/German(GR), English(US)/Italian(IT), English(US)/French(FR), and English(US)/Spanish(SP).

o	Depending upon the size of the FLASH device used for a particular product, up to 32 languages may be present at one time in the BIOS.

Hard Disk Changes

Beta 9.01

o	User definable parameters are available on a per drive basis.  This means each of the four drives may have unique user defined parameters.

o	The DMA selection (Auto-Configured or Disabled) may be set on a per drive basis.  (The ability to select the DMA transfer mode has been removed.)

o	The Sector/Block selection (Auto-Configured, 8 Sectors/Block, 4 Sectors/Block, or Disabled) for multiple sector transfers may be set on a per drive basis.  (The ability for finer resolution of Sector/Block size has been removed.)

o	The ability to disable fast PIO modes has been added.  This selection (Auto-Configured or Disabled) may be set on a per drive basis.

o	The Translation selection (Auto-Configured, Logical Block Addressing, Extended Cylinder/Head/Sector or Standard Cylinder/Head/Sector) may be set on a per drive basis.

o	A Hard Disk Pre-Delay has been added to the Boot Options screen.  This option sets a fixed amount of time to wait in POST before attempting to initialize any of the hard disks.  This delay occurs only once before calling the hard disk initialization code.  Because POST is so fast on this version of BIOS, many drives have not finished their power on self-test routines by the time the BIOS reaches its hard disk initialization code.  For certain drives, if the BIOS attempts to query the drive before it has finished its self-test, the drive may hang.  In an attempt to accommodate a user with one of these drives this option has been made available.  (This option is available on some current products.)

Chicago Plug and Play

Beta 9.01

o	Plug and Play version 1.2 will be supported in the Phase II BIOS.

o	Setup menus are still TBD.

New Int 15h Extensions

o	New Int 15h Extensions for Extended Memory and Memory Map have been added.

o	Function E801 has been added to report the amount of contiguous memory above 1Mb.

o	Function E820 has been added to report a full memory map of the system.  This function is used by Chicago and newer versions of Windows NT.

Other Changes

o	A setup field has been added to enable/disable the Guaranteed Access Time (GAT) Mode for ISA Master and DMA devices.  This feature may enhance the performance of ISA Master and DMA devices while degrading the performance of other non-ISA based devices.  Disabling this feature may improve sound quality on some ISA based sound cards.

o	A setup field has been added to enable/disable Byte Merging on PCI.  This feature enhances performance but may break some PCI graphics cards.

Known Errata With This Release

o	None.

Features Still To Be Added / Comments About This Release

o	None.

Notes:

Note 1:
The various O/Ss either do their own memory detection or issue a series of BIOS interrupts to determine memory size. The most common series of BIOS interrupts are INT 12 to get base memory.  Int 15 AH=88h is issued to get extended memory. Int 15h AX=E801h is issued to get memory above 64MB. NT-Daytona Beta 2 and Chicago issue Int 15h AX=E820.
A problem occurs because there is no standard as to what Int 15h AH=88 returns. Microsoft expects up to 63MB UNLESS E801 is supported , when they expect only 15MB maximum. If Microsoft sees greater than 15MB they limit the memory to the AH=88 value and ignore the E801 results. Some O/Ss in the above situation limit memory to 16MB. Some O/Ss except Int 15 AH=88 to return up to 63MB and look at E801 for memory above 64MB.

Eliminating the Int 15h AX-E801 support allows all O/S to handle up to 64MB using the Int 15h AH=88h. Those O/S that support Int 15h AX=E820h will handle memory above 64MB correctly.

5.25" Floppy fix, misc. changes (Fab C)

Minor changes to the keyboard interface circuitry were made to improve compatibility with a wider range of keyboards. The changes were made to the Keyboard CLK and DATA signals.  A 470 pf capacitor from Vcc to each of the signals was removed, and the 10K ohm pull-up resistors for these signals were replaced with 4.7K ohm resistors.  The 33 ohm series resistors on the floppy drive signals were replaced with 22 ohm series resistors.  This will improve compatibility with older 5¼" floppy drives that use 150 ohm pull-up resistors on these signals.  Also, several 1K ohm pull-up resistors on ISA control signals were replaced with 330 ohm resistors to provide better pull-up capability, and the 6.8K ohm resistors on the LBX were replaced with 2.7K ohm resistors to improve the PLL tracking.

PCMC, BIOS, RTC Socket, diode (Fab C)

The PCMC component stepping changed from A-1 to A-3.  The A-3 step corrects several errata that were present with the A-1 step.  Among the features that changed are:

•	L2 cache placed in Write Back mode

•	CPU to DRAM Posting Buffers enabled

•	PCI to DRAM Posting Buffers enabled

•	CPU to PCI Posting Buffers enabled

•	CACHE# functionality enabled

•	PCMC "Parked" on the PCI bus

•	Resource Locking (NOT Bus) mode enabled

•	DRAM timing set to 8-4-4-4 Timing

•	0-Active RAS mode set

•	Burst of 4 Refresh mode set

•	RAS Only Refresh mode set

A new BIOS (1.00.06.AF1) was cut in to take advantage of the improved features of the PCMC A-3.  This BIOS also corrects several bugs introduced with BIOS 1.00.05.AF1 when support was added for the PCI IDE add-in card.  BIOS 1.00.06.AF1 is downward compatible and will work on boards with either the A-1 or A-3 step of the PCMC.  BIOS updates are available on the Intel BBS (916-356-3600).

The Real Time Clock (RTC) socket was removed to improve motherboard reliability.  Instances have been reported where the RTC worked loose from the socket during shipping.  The expected life of the battery is greater than 10 years and should not need to be replaced during the life of the product.

The diode in the fan circuit was changed.  The new diode will have an increased current rating to accommodate the wide variety of fans that exist.  The old diode being was rated at 180 mA, the new diode is rated at 380 mA.

IDE Multiple Sector translation errata is fixed.

Several cache errata.  (Host to DRAM Posting Disabled)

Int 14 Hang.  (BIOS Stack Corruption)

Updated PCI code.

Disabled PCMC diagnostic bit.

Sped up block move code.

Fix to allow non-compliant TSENG video card to work.

Fixed System Timer reset errata.

Fixed C: Only Boot Option.

Changed Delete to F1 in POST message.

Changed 661 to 665 in Setup message.

Fixed keyboard stuck key reporting

Fixed PCI Resource allocation errata.

Fixed PCI resource allocations for mixed ISA/PCI environment.

Fixed ISA resource allocations for small ISA(2K) BIOSs.

Port 92H removed from list of supported A20 methods.

PCI bug fixed to limit Configuration space reads/writes to devices 00-0FH. Reads to devices 10-1FH return FFs and writes are aborted.

New Features Included in this Release

The feature Enhanced ISA Timing has been added.  This feature, when enable, will set the ISA Bus Clock Speed to 10/11MHz based upon the CPU Speed (60/66MHz).  Some ISA devices may not function properly with this feature enabled.

The feature IDE DMA has been added.  Options are [Disabled, Standard, Type B, Type F].  The field will specify the 'Maximum' DMA transfer speed used.  Some drives, like the WD Caviar 2340, will report as only supporting 'Standard' DMA instead of Type F as spec'd by WD.  The text 'Standard' is used instead of 'Compatible' for string space reasons.  See comments about Hard Drives for more information about IDE DMA.

The feature to select the Multiple Sector Mode transfer size has been added.  This will allow the user to specify a Sector/Block size that is smaller than the drive maximum if desired for performance reasons.  The text 'S/B' is used to represent 'Sectors/Block' for string space reasons.

Password Services are completely functional with the exception of Network Password.  (See Known Errata.)

Manufacturing mode is fully functional.

User Flashable logos are now supported.

If a PCMC Rev. A-1 is detected, the cache will be enabled in Write Back mode.

Comments

To enter setup:  Press and hold the DEL of F1 key as you power on the machine or, Press and hold the DELor F1 key as you do a front panel reset or, Press CTRL-ALT-DEL and remain holding the DEL key after you release the CTRL-ALT keys.  Once you see the Memory scroll, you may release the DEL key.  The Setup program will be entered after the Floppy/Hard Drive and Option ROM initialization.

This BIOS will auto-detect the Video, so there are no options in Setup for video configuration.  This BIOS will not support CGA 25x40 mode for POST.

Setup allows you to disable Memory Tests Above 1M and Memory Parity.  Disable the Memory Test Above 1M to speed execution of POST.

Shadowing is always enabled in this BIOS.  That means if you install an add-in card and it has a BIOS, on it then that BIOS will be shadowed BY DEFAULT.  If the card you install cannot be shadowed, then you must configure the Disable Shadow Memory options in the Advanced Setup Menu according to your add-in card.

Turbo/Deturbo Hot Keys are as follows:  CTRL-ALT-PLUS will disable Deturbo Mode.  CTRL-ALT-MINUS will enable Deturbo Mode.  CTRL-ALT-SHFT-PLUS will enable the cache, and CTRL-ALT-SHFT-MINUS will disable the cache.

This BIOS auto-configures the installed memory.  This means if you remove or add memory you will not get a configuration error.  The change in memory will automatically be accounted for.

This version of the BIOS fully supports auto-configuration of IDE drives that respond to the Identify Drive command.  Drives that either are not IDE or do not respond to this command are not supported by this BIOS.

Some IDE drives violate the Reset Response conditions as specified in the ATA Specification.  To resolve this problem and still take advantage of the drives auto-configuration capabilities, fields have been added to CMOS to allow the user to tell the BIOS how long to wait for the drive to recover from reset.  These fields may be configured for 0, 5, 15 or 31 seconds.  Five seconds is the default value.  If you know that you will never have a drive installed for a particular drive letter, then you may set this time-out value to zero seconds.  If your drive is not recognized from a power on, then you may need to set this parameter to 15 or 31 seconds for the particular drive.  If the BIOS waits for the specified amount of time and a drive is still not found, then any further initialization of drives will be stopped and POST will continue.

In some Master/Slave configurations you will need to pay careful attention to the drives jumper settings.  I have tried several combinations with over 15 different drives and have yet to find a combination that cannot be made to work with the proper drive jumpering.  Many drives will require that you configure them as a Master or Slave, AND indicate that a slave is present by setting another jumper.  If you have questions regarding your particular drive, please contact the tech support hotline for the particular drive manufacturer.

As the BIOS detects IDE drives, it will display a message saying the drive has been installed and any information contained in the Model fields of the Identify Drive command.  If the BIOS detects an error or finds that a drive does not exist then this message will not be displayed.  Since the BIOS cannot determine whether a drives absence or failure is due to a 'real' failure or by Drive 0 responding to Identify Drive issued to Drive 1, AN ERROR MESSAGE WILL NOT BE DISPLAYED.

If you are using IDE DMA with Windows (3.0 or 3.1), you will need to add DMABufferSize=80 to the [386Enh] section of SYSTEM.INI.

Technical Product Summary - Board Level Features - CPU
CPU

The Premiere/PCI Baby-AT motherboard is designed to operate with either a 60 MHz or 66 MHz Pentium microprocessor. This processor is compatible with the 8086, 80286, i386™ and i486™ CPUs. It supports both read and write burst mode bus cycles, and includes an on-chip 16 KB cache which is split into 8 KB code and 8 KB data caches employing a write-back policy. The Pentium processor also integrates an advanced numeric coprocessor which significantly increases the speed of floating point operations, while maintaining compatibility with i486™DX math coprocessors and complying with ANSI/IEEE standard 754-1985.

Premiere/PCI Baby-AT motherboards equipped with 66 MHz Pentium processors have a voltage control circuit that regulates Vcc to the CPU and frequency synthesizer. The voltage regulation accomodates a variety of Intel CPUs and increases the overall robustness and reliability of the motherboard. Boards without the voltage regulator circuitry cannot reliably use 66 MHz Pentium processors.

The motherboard contains two mounting holes which allow a dedicated fan to be located directly in front of the CPU socket. A 12 volt connector suitable for a CPU fan is located close to the mounting holes.


Performance Upgrade

A 273-pin Type 4 Zero Insertion Force socket provides users with a performance upgrade path using Pentium OverDrive processors. The OverDrive processor being developed for use in this socket will provide performance beyond that delivered by the Pentium microprocessor.


Second Level Cache

The Pentium processor's internal cache is complemented with a 256 KB direct mapped, write-back second level cache implemented with eight 32Kx8, 15 ns SRAM devices. Tag and control logic is contained in the 82434LX PCMC core chip.


System Memory

The Premiere/PCI motherboard provides four 72-pin SIMM sites for memory expansion. The sockets support 256K x 36 (1 MB), 512K x 36 (2 MB), 1M x 36 (4 MB), 2M x 36 (8 MB), 4M x 36 (16 MB), and 8M x 36 (32 MB) SIMM modules. Minimum memory size is 2 MB and maximum memory size, using four 8M x 36 SIMM modules, is 128 MB. Memory timing requires 70 ns fast page devices. Parity generation/checking is provided for each byte. Non-parity 32 bit SIMMs also may be used, in which case the parity generation/checking circuitry is automatically disabled.

The four sockets are arranged as Bank A and Bank B, with each bank consisting of two sockets and providing a 64-bit wide data path and 8 parity bits. Both SIMMs in a bank must be of the same memory size and type, although Banks A and B may have different types of memory installed. Bank A only, Bank B only, or both banks may be populated. There are no jumper settings required for the memory size, which is automatically detected by the system BIOS. Tin-lead SIMMs should be used when adding DRAM.

The memory array is controlled by the Intel 82434LX PCMC and data buffering is provided by two Intel 82433LX Local Bus Extension devices.


Expansion Slots

Up to seven expansion slots may be populated on the Premiere/PCI Baby-AT motherboard. Expansion cards are oriented perpendicular to the motherboard.

There are five ISA bus expansion connectors and three PCI expansion connectors. One slot is shared by connectors that will accommodate either an ISA or a PCI expansion card, but not both at the same time. All three PCI expansion slots accept PCI master cards to fully support the PCI specification.

The motherboard design limits the length of add-in cards in some slots. The height of the CPU heat sink limits the use of the two PCI connectors at J10C1 and J10C2 to less than full-length devices. The length of cards installed in the ISA connector at J10F1 may be limited if a SIMM is installed in the vertical SIMM socket (J3F1). And the location of the serial port header may limit the type of card that can be installed in the ISA connector at J10G1.

PCI 3.3 Volt Capabilities

To maintain strict compliance with the PCI specification, the motherboard provides a connector which can be used to route 3.3 volt power to the PCI slots. The connector may be used with a separate 3.3 volt power supply or with a custom designed voltage converter.


Peripheral Component Interconnect (PCI) Chip Set

The Intel Mercury chip set consists of one 82434LX PCI/Cache/Memory Controller (PCMC), two 82433LX Local Bus eXtension (LBX) devices, and one 82378IB System I/O (SIO) bridge chip. The Mercury chip set provides the following functions:

•	CPU reset control

•	CPU L1 cache control

•	CPU burst mode control

•	CPU interface control

•	Integrated second level write-back cache controller with tag comparator

•	Fast Page-mode DRAM controller

•	Burst memory read/write control logic

82434LX PCI/Cache/Memory Controller (PCMC)

The 82434LX provides all control signals necessary to drive a second level cache and the DRAM array, including multiplexed address signals. It also controls system access to memory and generates snoop controls to maintain cache coherency.


82433LX Local Bus eXtension (LBX)

There are two 82433LX components which provide data bus buffering and dual port buffering to the memory array. Controlled by the 82434LX, the 82433LX devices add one load each to the PCI bus and perform all the necessary byte and word swapping. The devices include memory and I/O write buffers.


82378IB System I/O (SIO)

The 82378IB integrates seven 32-bit DMA channels, five 16-bit timer/counters, two eight-channel interrupt controllers, NMI logic, ISA refresh address generation, and PCI/ISA bus arbitration circuitry together onto the same device.

Detailed information on the chip set is available in the Intel 82430 PCISet data sheet.


RZ1000 PCI IDE INTERFACE

The Premiere/PCI Baby-AT motherboard offers two IDE channels: one on the PCI local bus and one on the ISA bus. PCI-based IDE provides performance much improved over the traditional ISA-based IDE.

PCI to IDE Interface Circuit

IDE PHYSICAL Interface


PCI to IDE Interface Circuit

An onboard PCI to IDE interface is provided by the PCTech RZ1000 component and a specially-tuned system BIOS, which is fully compatible with existing IDE software. The RZ1000 provides a 32-bit buffered interface to two IDE drives, allowing these drives to be accessed at full PCI bandwidth. The component also supports Enhanced IDE Mode 3 timing, allowing the drive to transfer data at its full bandwidth. The system BIOS provides transparent access to these features, as well as support for Logical Block Addressing (LBA) which allows the use of drives larger than 528 MB. The PCI IDE interface functions as the primary interface using Interrupt 14. A secondary IDE interface (IRQ15) is provided by the SMC 37C665 I/O controller.


IDE PHYSICAL Interface

The PCI IDE physical interface consists of a dedicated 40-pin header connector (J11F1). A separate 40-pin connector (J9G1) is dedicated to the SMC 37C655 IDE interface. When the on-board IDE controllers are enabled, the RZ1000 is the primary interface and the ISA IDE controller is the secondary interface.


SMC 37C665 Super I/O Controller

Control for the integrated serial ports, parallel port, floppy drive and ISA IDE hard drive interface is incorporated into a single component, the SMC FDC37C665. This component provides:

•	Two NS16C552-compatible UARTs with send/receive 16 byte FIFO

•	Multi-mode bi-directional parallel port

- Standard mode; IBM* and Centronics compatible

- Enhanced Parallel Port (EPP) with BIOS/Driver support

- High Speed mode; Extended Capabilities Port (ECP) compatible

•	Industry standard floppy controller with 16 byte data FIFO (2.88 MB floppy support)

•	IDE hard disk decode and chip select

Header pins located near the back of the board allow cabling to use these interfaces. The serial ports can be set to various addresses or disabled (see

When the cursor is placed on one of these fields and it is selected by hitting the Enter Key, the Hard Disk Sub-Menu appears (see below) allowing parameters which affect the drives to be set.

Note:	Disk drive assignments

Drive letters will be assigned to physical drives as follows:

PCI IDE Interface Only

Master	C:

When drives have multiple partitions on them, partitions beyond the primary partition will be assigned in ascending order, based on available drive letters and other installed drives.  Partitions are assigned to primary partitions first (across multiple drives), and then to secondary partitions.  This means that when there are multiple drives with multiple partitions, the logical drive numbering scheme may result in discontiguous logical partitions on the same physical drive.

For instance, if there is a "Drive 1" with two partitions which is a Master on the PCI IDE interface, a "Drive 2" with three partitions which is a Slave on the PCI interface, and a "Drive 3" with two partitions which is a master on the ISA interface the drive letters will be assigned as follows:

    Hard Disk Sub-Menu

Hard Disk Type

Auto Configured -- default

User Definable

Number of Cylinders

Number of Heads

Number of Sectors

If	Hard Disk Type = Auto Configured

Then parameters reported by drive

If	Hard Disk Type = User Definable

Then parameters entered by user

The Number of Cylinders, Number of Heads, and Number of Sectors  fields display what is reported by the drive if Hard Disk Type is set to Auto Configured.  If Hard Disk Type is set to User Definable then these fields are entered by the user. Hard Disk Type should be set to Auto Configured unless the drive was formatted on another system with parameters different than those reported by the drive.

Maximum Capacity

Value calculated from Cylinder, Head, and Sector info above

Initialization Timeout

Disabled

5 Seconds

10 Seconds -- default

31 Seconds

Initialization Timeout selects the number of seconds the BIOS will wait to determine if an IDE drive is present, after initiating a transaction with the drive.  If a drive is present and responds to the BIOS before the Initialization Timeout period, then the BIOS will proceed, i.e. there is no boot-time penalty for a large value when a drive is present.  If a drive is not present, then the BIOS will wait the Initialization Timeout period before proceeding.  If a drive is present, but does not respond to the BIOS within the Initialization Timeout range, then the BIOS will not see the drive and it will not be accessible.  This value should be set to Disabled for any IDE drives not installed.  This parameter works in conjunction with the Hard Disk Pre-Delay parameter contained in the Boot Options sub-menu of the Main menu.

IDE Translation Mode

Standard CHS -- default

Logical Block

Extended CHS

Auto Detected

The IDE Translation Mode parameter controls the way in which the BIOS interacts with the drive in terms of drive geometry.  Proper choice is dependent upon the drive's size, capabilities, and the operating system (OS) used.

Standard CHS is the translation mode that has been in use for years.  Its use limits IDE capacity to a maximum of 528 Megabytes regardless of the size of the drive used.

Logical Block mode overcomes the 528 MB maximum size limitation imposed by Standard CHS mode. It should be used only when the drive supports LBA (Logical Block Addressing), and the OS supports LBA, or uses the BIOS to access the disk.

Extended CHS mode also overcomes the 528 MB maximum size limitation imposed by Standard CHS mode.   It can be used with drives which are larger than 528 MB, but do not support LBA mode.

Auto Detected allows the BIOS to examine the drive and determine the optimal mode. The first choice is to utilize Logical Block  mode if it is supported by the drive. The second choice is to utilize Extended CHS   mode if the drive topology allows.  If neither of the above two methods are possible, then Standard CHS mode is used.   Important NOTE: When set to Auto Detected the BIOS will detect what the drive is capable of, not the translation mechanism which was used to format the drive.  If a drive is run in a mode other than the mode in which  it was partitioned and formatted, unpredictable results may occur, including data loss.

Different operating systems have different abilities regarding IDE Translation Modes:

UNIX operating systems (as currently implemented) do not support either LBA or ECHS and must utilize the Standard CHS method. UNIX can support drives larger than 528 MB, but does so in its own way.

OS/2 2.1 can support LBA, ECHS or Standard CHS methods . Note that LBA support may require a switch setting on an OS/2 driver in order to operate in that mode. (*)

OS/2 2.0 & Novell Netware can support either ECHS or Standard CHS methods, but not LBA.

DOS & Windows can support LBA, ECHS or Standard CHS methods. If the "Fast 32-bit IDE" option of Windows is utilized, make sure to use the  Standard CHS setting only, unless a version of WDCDRV.386 is being used which supports these advanced geometrys.  You will get better performance NOT using "Fast 32-bit IDE" if using a drive which employs Mode 3 PIO on the PCI interface, unless using a version of WDCDRV.386 which supports these advanced modes.

Multiple Sector Setting

Disabled

4 Sectors/Block

8 Sectors/Block

Auto Detected -- default

The Multiple Sector Setting  field controls the number of sectors which are transferred by an IDE drive per interrupt generated.  If set to Disabled, then an interrupt will be generated for each sector transferred, even if the OS issues a multi-sector transfer.  If set to 4 Sectors/Block or 8 Sectors/Block then 4 or 8 sectors will be transferred per interrupt (for a request that is as large as, or larger than 4 or 8 sectors).  If Auto Detected is chosen, then x sectors will be transferred per interrupt, where x is the maximum value supported by the drive.  If a drive does not support multiple sectors/block then the BIOS will ignore this setting.  If the drive does not support the specific number (4 or 8) of sectors chosen, then the BIOS will default to the largest number of sectors the drive supports that are smaller than the chosen value.

Fast Programmed I/O Modes

Disabled

Auto Detected -- default

The Fast Programmed I/O Modes field controls the speed in which Programmed I/O (PIO) transfers occur on the PCI IDE interface.  If set to Disabled, transfers occur at an un-optimized (Mode 0) speed.  If set to Auto Detected, transfers occur at the rate which the drive reports as its maximum (up to and including the maximum mode 3 timing).  This field should only be set to Disabled if a drive is being used which incorrectly reports an ability to function with advanced timings.


    Language

English (US)

..

..

The Language: field controls the language of the text strings used in Setup and the BIOS.  Any installed language will appear as an option in its own language (for example, German will appear as Deutch).  Only installed languages will appear as options.  Language may be installed using the FMUP utility and the appropriate .LNG file.


    Boot Options Sub-Menu

When the cursor is placed the Boot Options: field and it is selected by hitting the Enter Key, the Boot Options Sub-Menu appears allowing parameters which affect the boot process to be set.

Boot Sequence

C: First, Then A:

A: First, Then C: -- default

C: Only

A: Only

The field controls the order in which the BIOS attempts to boot from the hard and floppy drives.

System Cache

Disabled

Enabled -- default

The System Cache field controls both the primary and secondary caches. Setting System Cache Disabled to will hurt performance, but might be required when running software which utilizes software timing loops and needs to be slowed down to execute properly.

Boot Speed

Turbo -- default

De-turbo

The Boot Speed field controls the system CPU cycles.  De-turbo mode slows the CPU by disabling system cache and adding increased refresh cycles.  It does not reduce CPU speed to 4.77Mhz or 8Mhz AT class machines.

Num Lock

Off -- default

On

The Num Lock field controls whether the keyboard Num Lock function is turned on or off when the system is booted.

Setup Prompt

Disabled

Enabled -- default

The Setup Prompt field controls whether the "Press <F1> Key To Enter Setup" message is displayed during POST (Power On Self Test).It does not control access, just the message.

Hard Disk Pre-Delay

Disabled

1 Second

2 Seconds

3 Seconds -- default

4 Seconds

5 Seconds

6 Seconds

7 Seconds

The Hard Disk Pre-Delay provides a mechanism which delays the BIOS's attempt to initialize the first  IDE drive in the system.  It is necessary because certain drives take longer than others to "spin up" and might hang if they are accessed too soon after being powered up or reset.  The delay is only honored for the first drive accessed. This parameter works in conjunction with the Initialization Timeout parameter contained in the Hard Disk Sub-menu of the Main menu.  The two are added together.

It should be noted that this new addition to the BIOS Setup is the result of our speeding up the POST process.

Typematic Rate Programming

Default -- default

Override

The parameter controls whether default or user configurable values are used for Typematic Rate Delay and Typematic Rate (see below).  If Default is chosen then Typematic Rate Delay is set to 500 msec and Typematic Rate is set to 15.  If Override is chosen the following two parameters appear, allowing the user to customize these values.

Typematic Rate Delay

250 msec -- default

500 msec

750 msec

1000 msec

The Typematic Rate Delay field controls how long it takes for the keyboard auto-repeat function to start when a keyboard key is held down.

Typematic Rate

6 char/sec -- default

8 char/sec

10 char/sec

12 char/sec

15 char/sec

20 char/sec

24 char/sec

30 char/sec

The Typematic Rate field controls the speed characters repeat when you hold down a keyboard key.  The higher the number, the faster the repeat.

Video Mode

The Video Mode  field is informative only.

Mouse

The Mouse  field is informative only.  If a PS/2 style mouse is installed, this field will display "Installed".  If the system does not support a PS/2 style mouse, or if it does and the mouse is not installed, this field will display "Not Installed".

Base Memory

This Base Memory field is informative only.   There is another Base Memory field which can be changed in the Advanced Chipset Configuration Sub-Menu of the Advanced menu.

When set to Auto, on board  system peripherals (IDE drives, Floppy Drive, Serial Ports, Parallel Port) are automatically configured during power up.  When set to Manual, system peripherals must be explicitly configured.  The following 6 fields (PCI IDE Interface to Parallel Port Address) are only user accessible when Configuration Mode is set to Manual.

PCI IDE Interface

 	Enabled -- default

Disabled

Standard ISA IDE Interface

Enabled -- default

Disabled

Floppy Interface

Enabled -- default

Disabled

The PCI IDE Interface, Standard IDE Interface, and Floppy Interface  fields allow these drive interfaces to be individually enabled or disabled.

Serial Port 1 Address

Disabled

COM1, 3F8h -- default

COM2, 2F8h

COM3, 3E8h

COM4, 2E8h

Serial Port 2 Address

Disabled

COM1, 3F8h

COM2, 2F8h -- default

COM3, 3E8h

COM4, 2E8h

The Serial Port 1 Address, Serial Port 2 Address fields allow the user to select the I/O ports used by these interfaces.  If a COM port is chosen for one of the Serial Port Addresses, it will not appear in the option list for the other Serial Port Address, i.e. if one of the Serial Port Addresses is set to Disabled, then there will be four choices for the other serial port address.  Otherwise there will be three choices.

Parallel Port Address

Disabled

LPT3, 3BCh

LPT1, 378h -- default

LPT2, 278h

The Parallel Port Address fields allow the user to select the I/O ports used by these interfaces.

Parallel Port Mode

Compatible -- default

Extended

When set to Compatible, the parallel port will be set up in a mode compatible with the original AT.  When set to Extended the parallel port will be set up in the most advanced mode allowed by the chipset (ex. ECC, ECP).

Serial Port 1 IRQ

Interrupt Used

Serial Port 2 IRQ

Interrupt Used

Parallel Port IRQ

Interrupt Used

The Serial Port 1 IRQ, , Serial Port 2 IRQ and Parallel Port IRQ  fields display the interrupts used by the Serial and Parallel Ports.  These values may not be changed by the user.  If an interface is disabled via the Serial Port 1 Address, Serial Port 2 Address, or Parallel Port Address fields, then the associated interrupt is not displayed, and is available for use by add in cards.


    Advanced Chipset Configuration Sub-Menu

Base Memory Size

512KB

640 KB -- default

The Base Memory Size field controls the mapping of addresses between 512K and 640K (80000h-9FFFFh).  If 512KB is chosen then accesses between 512K and 640K are directed to the ISA bus.  When 640 KB is selected accesses between 512K and 640K are directed to system DRAM.  Unless using an ISA card which requires access to this particular address range this field should be set to 640 KB.

ISA Bus Speed

Compatible -- default

Enhanced

The ISA Bus Speed field controls the speed of the ISA Bus clock.  If set to Compatible the speed will fall within the limits defined by the IBM AT Technical Reference (6-8.33 Mhz).  If set to Enhanced the speed will be greater than the maximum defined by the IBM AT Technical Reference manual.  Modern ISA cards can operate with the enhanced speeds,  however some older cards can experience difficulties.  ISA performance will be enhanced when ISA Bus Speed is set to enhanced.   The actual value of the Bus Clock when set to Compatible or Enhanced is dependent upon the external frequency of the CPU:

External Frequency	Compatible	Enhanced
60 Mhz	7.5 Mhz	10 Mhz
66 Mhz	8.25 Mhz	11 Mhz
Byte Merging

Enabled

Disabled -- default

Byte Merging is a feature which increases performance for older applications which write to video memory in bytes instead of words.  However, this feature is not supported on all PCI video cards.  For best performance this field should be enabled unless a PCI graphics card which does not support this feature is used.  If this field is enabled and used with a card which lacks support video corruption will be seen in some video modes.

PCI IDE Prefetch Buffers

Enabled -- default

Disabled

This field is used to disable a set of prefetch buffers in the PCI IDE controller.  Disabling the buffers may be required when using Operating Systems (such as NT and OS/2) which do not use the BIOS to access the hard and do not disable interrupts when completing a programmed I/O operation.  Setting PCI IDE Prefetch Buffers to Disabled has negative performance implications.  Some operating systems may provide a patch to correct this problem, contact the operating system vendor for details.  A second work around is to disable the PCI IDE interface and use the ISA IDE interface only.

ISA LFB Size

Disabled -- default

1 MB

3 MB

7 MB

The ISA Video Linear Frame Buffer Size provides a mechanism for creating a hole in the system memory map.  Accesses made to addresses within this hole will be directed to the ISA bus instead of main memory.  This should be set to Disabled  unless you are using an ISA video card with a linear frame buffer or other ISA cards which require greater than 64K of memory and you are not using the Plug and Play run-time utilities (Configuration Manager & ISA Configuration Utility).

ISA LFB Base Address

Dependent upon ISA LFB Size

If	ISA LFB Size	Then	ISA  LFB Base Address
	Disabled		N.A.
	1 MB`		15 MB
	3 MB		13 MB
	7 MB		9   MB
The ISA Video LFB Base Address field displays the starting address of the ISA memory hole if a value other than Disabled is chosen for the ISA Video LFB Size parameter.  If  ISA Video LFB Size is set to disabled, then this field does not appear.  This field is informative only, i.e. it cannot be changed by the user.

Video Palette Snoop

Disabled -- default

Enabled

The Video Palette Snoop field controls the ability of a PCI graphics cards to "snoop" write cycles to an ISA video card's color palette registers.  This should normally be set to Disabled.  It should only be set to Enabled if:

An ISA card connects to a PCI graphics card via the VESA connector

AND that ISA card connects to a color monitor.

Note: This field will not show up if using the B stepping of a Cirrus 5434 graphics controller.

Latency Timer (PCI Clocks)

Number between 0 and 256

66 -- default

The Latency Timer (PCI Clocks) field controls the length of time an agent on the PCI bus can hold the bus when another agent has requested the bus.  Its default value is 66.  In general this should not be changed.  If there are latency sensitive cards in the system (such as audio cards and/or network cards with small buffers) this can be set to a lower value to reduce latency.  If there are no latency sensitive cards in the system, but I/O intensive applications are being run, this can be increased to slightly improve performance.


    Plug and Play Configuration Sub-Menu

Configuration Mode

Use Setup Utility -- default

Use ICU

The Configuration Mode field is used to choose the method in which information about legacy ISA cards (ISA cards which do not have Plug and Play capabilities) is conveyed to the BIOS to allow the BIOS to set up PCI cards and ISA Plug and Play cards without conflicting with the legacy ISA cards.

If Use ICU is chosen, then the BIOS will depend upon information provided by run-time Plug and Play software (Configuration Manager and ISA Configuration Utility) to ensure that there are no conflicts with legacy ISA cards.  Only choose this method if your system is configured with these utilities and they are used. When Use ICU is chosen no other fields are displayed in this Sub-Menu.

If Use Setup Utility is chosen, then the BIOS will depend upon information provided by the user in the fields below to prevent conflicts between Plug and Play cards and legacy ISA cards.  If the Use Setup Utility is chosen, the user should not install and use run-time Plug and Play software (Configuration Manager and ICU).

ISA Shared Memory Size

Disabled -- default

16 KB

32 KB

48 KB

64 KB

The ISA Shared Memory Size field is used to define a block of system memory which will not be shadowed (shadowing is a technique which copies a block of memory from an add in card's ROM to the same address in  system memory to allow faster access to the code and achieve higher performance).  By default all upper memory is shadowed unless a block is un-shadowed using this and the ISA Shared Memory Base Address fields.

This field should be set to Disabled unless an ISA card is used which communicates with the CPU through a block of shared memory located in the upper memory area.  If set to a value other than Disabled  the ISA Shared Memory Base Address field will appear below.  Note that if a value of  64 KB is chosen, then the ISA Shared Memory Base Address field can only be set to D0000h or below.

ISA Shared Memory Base Address

C0000h

C4000h

C8000h

CC000h

D0000h

D4000h

D8000h

DC000h

The ISA Shared Memory Base Address field works in conjunction with the ISA Shared Memory Size.  See above.  This parameter is only displayed if the ISA Shared Memory Size parameter is not disabled.

IRQ 3*

IRQ 4*

IRQ 5

IRQ 7*

IRQ 9

IRQ 10

IRQ 11

IRQ 15*

Available

Used By ISA Card

* These options will not be visible if consumed by on-board resources (IRQ3 Serial Port 2, IRQ4 Serial Port 1, IRQ7 Parallel Port, IRQ 15, both IDE interfaces used).

The IRQ 3 - IRQ 15 fields are used to indicate whether individual interrupts are used by ISA legacy cards.  If not used, then they should be set to Available.  If used they should be set to Used By ISA Card.

Notes: All but one interrupt can be set to Used By ISA Card.  One must remain available for PCI cards which use interrupts to function.

On older systems that have the B stepping of the SIO PCI bridge component, only interrupts 9, 10 and 11 will show on this screen, even if additional interrupts are available.


    Security Menu

There are two types of passwords available, User Password and Administrative Password.  The User password can be used to control access to the Setup Utility, the keyboard upon initial boot, and the keyboard when used in conjunction with the Security Hot Key.  The Administrative Password is used to control access to the Setup Utility.  The following table describes the interaction between these passwords:

Password In Effect	Enter Setup with User Password	Enter Setup with Administrate Password	Boot
User Password Only	Can change all fields	N.A.	User Password Required
Administrative Password Only	N..A.	Can change all fields	No  Password Required
Both	Can change limited number of fields	Can change all fields	User or Administrative Password Required
If the Administrative Password is in effect and Setup is entered with the User Password only the following fields may be changed:

System Date

System Time

User Password

Security Hot Key

User Password is

Disabled -- default

Enabled

Administrative Password is

Disabled -- default

Enabled

The User Password is and Administrative Password is fields indicate whether the User and Administrative passwords have been set.  If neither the User Password is or the Administrative Password is fields are set to Enabled neither the Unattended Start or Security Hot Key (CTRL-ALT-) fields will be displayed.

Set User Password

When the Set User Password field is chosen the user is presented with one of two sub-menus.  If there is currently no User Password in effect the following menu appears:

Enter New Password_______

Confirm New Password_______

Press Enter or TAB to Accept

Press ESC to Abort

If there is already a User Password in effect, the following menu appears.  To disable the password, use a carriage return as the new password.

Enter Current Password_______

Enter New Password_______

Confirm New Password_______

Press Enter or TAB to Accept

Press ESC to Abort

Set Administrative Password

When the Set Administrative Password field is chosen the user is presented with one of two sub-menus.  If there is currently no Administrative Password in effect the following menu appears:

Enter New Password_______

Confirm New Password_______

Press Enter or TAB to Accept

Press ESC to Abort

If there is already an Administrative Password in effect, the following menu appears.  To disable the password, use a carriage return as the new password.

Enter Current Password_______

Enter New Password_______

Confirm New Password_______

Press Enter or TAB to Accept

Press ESC to Abort

Unattended Start

Disabled -- default

Enabled

The Unattended Start  field controls the point at which the User Password is required.  If set to Disabled  the User Password is required before the system boots, either from disk or the network.  The user will be prompted for the password with the text string "Enter Password (1):"

If set to Enabled the system will go through automatic boot activity (for instance running CONFIG.SYS and AUTOEXEC.BAT when booting DOS from disk), however the keyboard will be locked and the User Password must be entered to unlock it.  The BIOS does not provide any prompt string so it is suggested that the last thing that the automatic login sequence does is prompt the user for the password.

The Unattended Start field can only be set if a User Password is in effect.

Security Hot Key (CTRL-ALT-)

Alpha-Numeric Key

The Security Hot Key (CTRL-ALT-) field can be used to define a key which when entered in conjunction with the CTRL and ALT keys puts the system into secure mode (locks the keyboard).  When this Hot Key combination is entered the Num Lock, Caps Lock, and Scroll Lock LEDs on the keyboard will flash on and off in sequence, indicating to the user that the system is in secure mode (as opposed to being hung).


    Exit Menu

Exit Saving Changes

The Exit Saving Changes field is used to exit the Setup Utility saving the current state of all parameters.

When the Enter key is entered the following sub-menu is displayed:

Exit Saving Changes?

Press Enter to Continue

Press ESC to Abort

If the Enter key is selected then the Setup Utility will be exited with all parameters set to their current values.  If the ESC key is selected, then the user is returned to the Exit menu without effecting any change.

Exit Discarding Changes

The Exit Discarding Changes field is used to exit the Setup Utility discarding any changes made to Setup parameters.  When the Enter key is entered the following sub-menu is displayed:

Exit Discarding Changes?

Press Enter to Continue

Press ESC to Abort

If the Enter key is selected then the Setup Utility will be exited with changes to Setup parameters lost.  If the ESC key is selected, then the user is returned to the Exit menu without effecting any change.

Load Setup Defaults

The Load Setup Defaults field is used to load default values into all Setup parameters, except for the passwords.  When the Enter key is entered the following sub-menu is displayed:

Load Setup Defaults?

Press Enter to Continue

Press ESC to Abort

If the Enter key is selected then defaults are loaded into all Setup parameters, except for the passwords.  If the ESC key is selected, then the user is returned to the Exit menu without effecting any changes.

Discard Changes

The Discard Changes field is used undo any changes made to Setup parameters during this Setup session.  When the Enter key is entered the following sub-menu is displayed:

Discard Changes?

Press Enter to Continue

Press ESC to Abort

If the Enter key is selected then any changes made to Setup parameters are discarded.  If the ESC key is selected, then the user is returned to the Exit menu without effecting any changes.


    Appendix D  ) for details. The parallel port can be configured via the Setup program for various addresses or disabled, and can be set as bi-directional or output only when enabled.


Keyboard Interface

An Intel 8742 surface mount microcontroller contains the Phoenix Technologies-compatible keyboard/mouse controller code. An AT-style keyboard connector is located on the back panel side of the motherboard. The 5V line on this connector is protected with a PolySwitch* circuit which acts much like a self-healing fuse, re-establishing the connection after an over-current condition is removed. While this device eliminates the possibility of having to replace a fuse, care should be taken to turn off the system power before installing or removing a keyboard.

The 8742 microcontroller code supports Power-On/Reset (POR) password protection. The POR password is set via the Setup program. The keyboard controller also provides for the following "hot key" sequences:

•	CTRL-ALT-DEL: System software reset. This sequence performs a software reset of the system by jumping to the beginning of the BIOS code and running the POST operation.

•	CTRL-ALT+ and CTRL-ALT-: Turbo mode selection. CTRL-ALT- sets the system for de-turbo mode (emulation of an 8 MHz 80286 CPU) and CTRL-ALT+ sets the system for turbo mode (normal operation at 60 MHz). Changing the Turbo mode may be prohibited by an operating system or application software. For example, the CPU speed cannot be changed when the CPU is in Protected Mode.


Dallas DS12887 Real Time Clock, CMOS RAM and Battery

The Real Time Clock (RTC) is implemented using a Dallas DS12887 device. The DS12887 is accurate to within 13 minutes/year and requires no external support (the battery and oscillator are integrated into the device). The internal battery has an estimated lifetime of ten years.

The RTC can be set via the BIOS SETUP Program. CMOS memory supports the standard 128byte batterybacked RAM, fourteen bytes for clock and control registers, and 114 bytes of general purpose non-volatile CMOS RAM. All CMOS RAM is reserved for BIOS use. The CMOS RAM can be set to specific values or cleared to the system default values using the BIOS SETUP program. Also, the CMOS RAM values can be cleared to the system defaults by using a hardware jumper. See


    Appendix B  Jumpers for detailed jumper configuration information.


System BIOS

The Premiere/PCI Baby-AT motherboard uses an American Megatrends Incorporated (AMI) ROM BIOS, which is stored in Flash EEPROM and easily upgraded using a floppy disk-based program. BIOS upgrades will be available for download from the Intel bulletin board system. In addition to the AMIBIOS, the Flash EEPROM also contains the Setup utility, Power-On Self Tests (POST), update recovery code, and the PCI auto-configuration utility. This motherboard supports system BIOS shadowing, allowing the BIOS to execute from 32-bit on-board write-protected DRAM.

The BIOS displays a sign-on message during POST identifying the type of BIOS and a five-digit revision code. First production units will display a revision code of 1.00.01.AF2 As BIOS updates occur, the revision number will increase to 1.00.02.AF2, and so on.

Information on BIOS functions can be found in the IBM PS/2 and Personal Computer BIOS Technical Reference published by IBM, and the ISA and EISA Hi-Flex AMIBIOS Technical Reference published by AMI. Both manuals are available at most technical bookstores.

FLASH Implementation

The Intel 28F001BXT 1 Mb FLASH component is organized as 128K x 8 (128 KB). The Flash device is divided into five areas, as described in Table 1.

System	FLASH Memory
F0000H-FFFFFH	64 KB Main BIOS
EE000H-EFFFFH	8 KB Boot Block (Not FLASH erasable)
ED000H-EDFFFH	4 KB ECSD Area (Plug'n'Play data)
EC000H-ECFFFH	4 KB BIOS Logo Area
E0000H-EBFFFH	48 KB Not Used
Table 1. Flash Memory Organization

The FLASH device resides in system memory in two 64 KB segments starting at E0000H, and can be mapped two different ways, depending on the mode of operation. In Normal Mode, address line A16 is inverted, setting the E000H and F000H segments so that the BIOS is organized as shown in the system address column above. Recovery mode removes the inversion on address line A16, swapping the E000H and F000H segments so that the 8 KB boot block resides at FE000H where the CPU expects the bootstrap loader to exist. This mode is only necessary in the unlikely event that a BIOS upgrade procedure is interrupted, causing the BIOS area to be left in an unusable state. For information on recovering the BIOS in the event of a catastrophic failure, refer to


    Appendix F  BIOS Upgrades and Recovery.


BIOS Upgrades

Flash memory makes distributing BIOS upgrades easy. A new version of the BIOS can be installed from a diskette. BIOS upgrades will available on the BBS for direct Intel customers.

The disk-based Flash upgrade utility (FMUP.EXE) has three options for BIOS upgrades:

The Flash BIOS can be updated from a file on a disk;

The current BIOS code can be copied from the Flash EEPROM to a disk file as a backup in the event that an upgrade cannot be successfully completed;

The BIOS in the Flash device can be compared with a disk file to ensure the system has the correct BIOS version.

The upgrade utility ensures the upgrade BIOS matches the target system to prevent accidentally installing a BIOS for a different type of system. Security to prevent unauthorized changes to the BIOS is provided via a write-protect jumper. The default setting is to allow BIOS upgrades. A recovery jumper is provided to allow recovery in the unlikely event of an unsuccessful BIOS upgrade. The jumper forces the ROM decode to access an 8 KB block of write protected recovery code in the Flash device.


Setup Utility

The ROM-based Setup utility allows the configuration to be modified without opening the system for most basic changes. The Premiere/PCI Baby-AT motherboard also incorporates many new capabilities into the Flash EEPROM, including:

Auto configuration of IDE hard disks (manual selection of the drive type is no longer required).

Support for two IDE disk interfaces (primary and secondary) providing access to 4 IDE devices (when a second IDE controller is added on the PCI or ISA bus).

An option allowing the user to assign a block of addresses below the 1 MB boundary as non-shadowed, non-cached. This area is primarily used for ISA expansion card ROM which causes timing problems when shadowed and cached, or for ISA expansion cards that contain dual port memory.

ISA interrupts may be assigned to add-in card ISA adapters, thereby informing the PCI configuration utility which interrupts not to use.

The Setup utility is accessible only during the Power-On Self Test (POST) by pressing the <DEL> or <F1> key after the POST memory test has begun and before boot begins. A prompt may be enabled that informs users to press the <F1> key to access Setup. A motherboard jumper can be set to prevent user access to Setup for security purposes. See

Identification string returned from drive

Not Installed

The Hard Disk C: through Hard Disk F: fields report the presence of, and identification string reported by, up to 4 physical IDE drives (two each of PCI and ISA).  When the cursor is placed on one of these fields and it is selected by hitting the Enter Key, the Hard Disk Sub-Menu appears (see below) allowing parameters which affect the drives to be set.

Note:	Disk drive assignments

Drive letters will be assigned to physical drives as follows:

PCI IDE Interface Only

Master	C:
Secondary	D:

ISA Interface Only

Master	C:
Secondary	D:

ISA & PCI IDE Interface Two Drives Used

PCI Master	C:

When drives have multiple partitions on them, partitions beyond the primary partition will be assigned in ascending order, based on available drive letters and other installed drives.  Partitions are assigned to primary partitions first (across multiple drives), and then to secondary partitions.  This means that when there are multiple drives with multiple partitions, the logical drive numbering scheme may result in discontiguous logical partitions on the same physical drive.

For instance, if there is a "Drive 1" with two partitions which is a Master on the PCI IDE interface, a "Drive 2" with three partitions which is a Slave on the PCI interface, and a "Drive 3" with two partitions which is a master on the ISA interface the drive letters will be assigned as follows:

    Hard Disk Sub-Menu

Hard Disk Type

Auto Configured -- default

User Definable

Number of Cylinders

Number of Heads

Number of Sectors

If	Hard Disk Type = Auto Configured

Then parameters reported by drive

If	Hard Disk Type = User Definable

Then parameters entered by user

The Number of Cylinders, Number of Heads, and Number of Sectors  fields display what is reported by the drive if Hard Disk Type is set to Auto Configured.  If Hard Disk Type is set to User Definable then these fields are entered by the user. Hard Disk Type should be set to Auto Configured unless the drive was formatted on another system with parameters different than those reported by the drive.

Maximum Capacity

Value calculated from Cylinder, Head, and Sector info above

Initialization Timeout

Disabled

5 Seconds

10 Seconds -- default

31 Seconds

Initialization Timeout selects the number of seconds the BIOS will wait to determine if an IDE drive is present, after initiating a transaction with the drive.  If a drive is present and responds to the BIOS before the Initialization Timeout period, then the BIOS will proceed, i.e. there is no boot-time penalty for a large value when a drive is present.  If a drive is not present, then the BIOS will wait the Initialization Timeout period before proceeding.  If a drive is present, but does not respond to the BIOS within the Initialization Timeout range, then the BIOS will not see the drive and it will not be accessible.  This value should be set to Disabled for any IDE drives not installed.  This parameter works in conjunction with the Hard Disk Pre-Delay parameter contained in the Boot Options sub-menu of the Main menu.

IDE Translation Mode

Standard CHS -- default

Logical Block

Extended CHS

Auto Detected

The IDE Translation Mode parameter controls the way in which the BIOS interacts with the drive in terms of drive geometry.  Proper choice is dependent upon the drive's size, capabilities, and the operating system (OS) used.

Standard CHS is the translation mode that has been in use for years.  Its use limits IDE capacity to a maximum of 528 Megabytes regardless of the size of the drive used.

Logical Block mode overcomes the 528 MB maximum size limitation imposed by Standard CHS mode. It should be used only when the drive supports LBA (Logical Block Addressing), and the OS supports LBA, or uses the BIOS to access the disk.

Extended CHS mode also overcomes the 528 MB maximum size limitation imposed by Standard CHS mode.   It can be used with drives which are larger than 528 MB, but do not support LBA mode.

Auto Detected allows the BIOS to examine the drive and determine the optimal mode. The first choice is to utilize Logical Block  mode if it is supported by the drive. The second choice is to utilize Extended CHS   mode if the drive topology allows.  If neither of the above two methods are possible, then Standard CHS mode is used.   Important NOTE: When set to Auto Detected the BIOS will detect what the drive is capable of, not the translation mechanism which was used to format the drive.  If a drive is run in a mode other than the mode in which  it was partitioned and formatted, unpredictable results may occur, including data loss.

Different operating systems have different abilities regarding IDE Translation Modes:

UNIX operating systems (as currently implemented) do not support either LBA or ECHS and must utilize the Standard CHS method. UNIX can support drives larger than 528 MB, but does so in its own way.

OS/2 2.1 can support LBA, ECHS or Standard CHS methods . Note that LBA support may require a switch setting on an OS/2 driver in order to operate in that mode. (*)

OS/2 2.0 & Novell Netware can support either ECHS or Standard CHS methods, but not LBA.

DOS & Windows can support LBA, ECHS or Standard CHS methods. If the "Fast 32-bit IDE" option of Windows is utilized, make sure to use the  Standard CHS setting only, unless a version of WDCDRV.386 is being used which supports these advanced geometrys.  You will get better performance NOT using "Fast 32-bit IDE" if using a drive which employs Mode 3 PIO on the PCI interface, unless using a version of WDCDRV.386 which supports these advanced modes.

Multiple Sector Setting

Disabled

4 Sectors/Block

8 Sectors/Block

Auto Detected -- default

The Multiple Sector Setting  field controls the number of sectors which are transferred by an IDE drive per interrupt generated.  If set to Disabled, then an interrupt will be generated for each sector transferred, even if the OS issues a multi-sector transfer.  If set to 4 Sectors/Block or 8 Sectors/Block then 4 or 8 sectors will be transferred per interrupt (for a request that is as large as, or larger than 4 or 8 sectors).  If Auto Detected is chosen, then x sectors will be transferred per interrupt, where x is the maximum value supported by the drive.  If a drive does not support multiple sectors/block then the BIOS will ignore this setting.  If the drive does not support the specific number (4 or 8) of sectors chosen, then the BIOS will default to the largest number of sectors the drive supports that are smaller than the chosen value.

Fast Programmed I/O Modes

Disabled

Auto Detected -- default

The Fast Programmed I/O Modes field controls the speed in which Programmed I/O (PIO) transfers occur on the PCI IDE interface.  If set to Disabled, transfers occur at an un-optimized (Mode 0) speed.  If set to Auto Detected, transfers occur at the rate which the drive reports as its maximum (up to and including the maximum mode 3 timing).  This field should only be set to Disabled if a drive is being used which incorrectly reports an ability to function with advanced timings.


    Language

English (US)

..

..

The Language: field controls the language of the text strings used in Setup and the BIOS.  Any installed language will appear as an option in its own language (for example, German will appear as Deutch).  Only installed languages will appear as options.  Language may be installed using the FMUP utility and the appropriate .LNG file.


    Boot Options Sub-Menu

When the cursor is placed the Boot Options: field and it is selected by hitting the Enter Key, the Boot Options Sub-Menu appears allowing parameters which affect the boot process to be set.

Boot Sequence

C: First, Then A:

A: First, Then C: -- default

C: Only

A: Only

The field controls the order in which the BIOS attempts to boot from the hard and floppy drives.

System Cache

Disabled

Enabled -- default

The System Cache field controls both the primary and secondary caches. Setting System Cache Disabled to will hurt performance, but might be required when running software which utilizes software timing loops and needs to be slowed down to execute properly.

Boot Speed

Turbo -- default

De-turbo

The Boot Speed field controls the system CPU cycles.  De-turbo mode slows the CPU by disabling system cache and adding increased refresh cycles.  It does not reduce CPU speed to 4.77Mhz or 8Mhz AT class machines.

Num Lock

Off -- default

On

The Num Lock field controls whether the keyboard Num Lock function is turned on or off when the system is booted.

Setup Prompt

Disabled

Enabled -- default

The Setup Prompt field controls whether the "Press <F1> Key To Enter Setup" message is displayed during POST (Power On Self Test).It does not control access, just the message.

Hard Disk Pre-Delay

Disabled

1 Second

2 Seconds

3 Seconds -- default

4 Seconds

5 Seconds

6 Seconds

7 Seconds

The Hard Disk Pre-Delay provides a mechanism which delays the BIOS's attempt to initialize the first  IDE drive in the system.  It is necessary because certain drives take longer than others to "spin up" and might hang if they are accessed too soon after being powered up or reset.  The delay is only honored for the first drive accessed. This parameter works in conjunction with the Initialization Timeout parameter contained in the Hard Disk Sub-menu of the Main menu.  The two are added together.

It should be noted that this new addition to the BIOS Setup is the result of our speeding up the POST process.

Typematic Rate Programming

Default -- default

Override

The parameter controls whether default or user configurable values are used for Typematic Rate Delay and Typematic Rate (see below).  If Default is chosen then Typematic Rate Delay is set to 500 msec and Typematic Rate is set to 15.  If Override is chosen the following two parameters appear, allowing the user to customize these values.

Typematic Rate Delay

250 msec -- default

500 msec

750 msec

1000 msec

The Typematic Rate Delay field controls how long it takes for the keyboard auto-repeat function to start when a keyboard key is held down.

Typematic Rate

6 char/sec -- default

8 char/sec

10 char/sec

12 char/sec

15 char/sec

20 char/sec

24 char/sec

30 char/sec

The Typematic Rate field controls the speed characters repeat when you hold down a keyboard key.  The higher the number, the faster the repeat.

Video Mode

The Video Mode  field is informative only.

Mouse

The Mouse  field is informative only.  If a PS/2 style mouse is installed, this field will display "Installed".  If the system does not support a PS/2 style mouse, or if it does and the mouse is not installed, this field will display "Not Installed".

Base Memory

This Base Memory field is informative only.   There is another Base Memory field which can be changed in the Advanced Chipset Configuration Sub-Menu of the Advanced menu.

    Peripheral Configuration Sub-Menu

Configuration Mode

 	Auto -- default

Manual

The Configuration Mode fields controls whether on board resources are manually or automatically set up.  When set to Auto, on board  system peripherals (IDE drives, Floppy Drive, Serial Ports, Parallel Port) are automatically configured during power up.  When set to Manual, system peripherals must be explicitly configured.  The following 6 fields (PCI IDE Interface to Parallel Port Address) are only user accessible when Configuration Mode is set to Manual.

PCI IDE Interface

 	Enabled -- default

Disabled

Standard ISA IDE Interface

Enabled -- default

Disabled

Floppy Interface

Enabled -- default

Disabled

The PCI IDE Interface, Standard IDE Interface, and Floppy Interface  fields allow these drive interfaces to be individually enabled or disabled.

Serial Port 1 Address

Disabled

COM1, 3F8h -- default

COM2, 2F8h

COM3, 3E8h

COM4, 2E8h

Serial Port 2 Address

Disabled

COM1, 3F8h

COM2, 2F8h -- default

COM3, 3E8h

COM4, 2E8h

The Serial Port 1 Address, Serial Port 2 Address fields allow the user to select the I/O ports used by these interfaces.  If a COM port is chosen for one of the Serial Port Addresses, it will not appear in the option list for the other Serial Port Address, i.e. if one of the Serial Port Addresses is set to Disabled, then there will be four choices for the other serial port address.  Otherwise there will be three choices.

Parallel Port Address

Disabled

LPT3, 3BCh

LPT1, 378h -- default

LPT2, 278h

The Parallel Port Address fields allow the user to select the I/O ports used by these interfaces.

Parallel Port Mode

Compatible -- default

Extended

When set to Compatible, the parallel port will be set up in a mode compatible with the original AT.  When set to Extended the parallel port will be set up in the most advanced mode allowed by the chipset (ex. ECC, ECP).

Serial Port 1 IRQ

Interrupt Used

Serial Port 2 IRQ

Interrupt Used

Parallel Port IRQ

Interrupt Used

The Serial Port 1 IRQ, , Serial Port 2 IRQ and Parallel Port IRQ  fields display the interrupts used by the Serial and Parallel Ports.  These values may not be changed by the user.  If an interface is disabled via the Serial Port 1 Address, Serial Port 2 Address, or Parallel Port Address fields, then the associated interrupt is not displayed, and is available for use by add in cards.


    Advanced Chipset Configuration Sub-Menu

Base Memory Size

512KB

640 KB -- default

The Base Memory Size field controls the mapping of addresses between 512K and 640K (80000h-9FFFFh).  If 512KB is chosen then accesses between 512K and 640K are directed to the ISA bus.  When 640 KB is selected accesses between 512K and 640K are directed to system DRAM.  Unless using an ISA card which requires access to this particular address range this field should be set to 640 KB.

ISA Bus Speed

Compatible -- default

Enhanced

The ISA Bus Speed field controls the speed of the ISA Bus clock.  If set to Compatible the speed will fall within the limits defined by the IBM AT Technical Reference (6-8.33 Mhz).  If set to Enhanced the speed will be greater than the maximum defined by the IBM AT Technical Reference manual.  Modern ISA cards can operate with the enhanced speeds,  however some older cards can experience difficulties.  ISA performance will be enhanced when ISA Bus Speed is set to enhanced.   The actual value of the Bus Clock when set to Compatible or Enhanced is dependent upon the external frequency of the CPU:

External Frequency	Compatible	Enhanced
60 Mhz	7.5 Mhz	10 Mhz
66 Mhz	8.25 Mhz	11 Mhz
Byte Merging

Enabled

Disabled -- default

Byte Merging is a feature which increases performance for older applications which write to video memory in bytes instead of words.  However, this feature is not supported on all PCI video cards.  For best performance this field should be enabled unless a PCI graphics card which does not support this feature is used.  If this field is enabled and used with a card which lacks support video corruption will be seen in some video modes.

PCI IDE Prefetch Buffers

Enabled -- default

Disabled

This field is used to disable a set of prefetch buffers in the PCI IDE controller.  Disabling the buffers may be required when using Operating Systems (such as NT and OS/2) which do not use the BIOS to access the hard and do not disable interrupts when completing a programmed I/O operation.  Setting PCI IDE Prefetch Buffers to Disabled has negative performance implications.  Some operating systems may provide a patch to correct this problem, contact the operating system vendor for details.  A second work around is to disable the PCI IDE interface and use the ISA IDE interface only.

ISA LFB Size

Disabled -- default

1 MB

3 MB

7 MB

The ISA Video Linear Frame Buffer Size provides a mechanism for creating a hole in the system memory map.  Accesses made to addresses within this hole will be directed to the ISA bus instead of main memory.  This should be set to Disabled  unless you are using an ISA video card with a linear frame buffer or other ISA cards which require greater than 64K of memory and you are not using the Plug and Play run-time utilities (Configuration Manager & ISA Configuration Utility).

ISA LFB Base Address

Dependent upon ISA LFB Size

If	ISA LFB Size	Then	ISA  LFB Base Address
	Disabled		N.A.
	1 MB`		15 MB
	3 MB		13 MB
	7 MB		9   MB
The ISA Video LFB Base Address field displays the starting address of the ISA memory hole if a value other than Disabled is chosen for the ISA Video LFB Size parameter.  If  ISA Video LFB Size is set to disabled, then this field does not appear.  This field is informative only, i.e. it cannot be changed by the user.

Video Palette Snoop

Disabled -- default

Enabled

The Video Palette Snoop field controls the ability of a PCI graphics cards to "snoop" write cycles to an ISA video card's color palette registers.  This should normally be set to Disabled.  It should only be set to Enabled if:

An ISA card connects to a PCI graphics card via the VESA connector

AND that ISA card connects to a color monitor.

Note: This field will not show up if using the B stepping of a Cirrus 5434 graphics controller.

Latency Timer (PCI Clocks)

Number between 0 and 256

66 -- default

The Latency Timer (PCI Clocks) field controls the length of time an agent on the PCI bus can hold the bus when another agent has requested the bus.  Its default value is 66.  In general this should not be changed.  If there are latency sensitive cards in the system (such as audio cards and/or network cards with small buffers) this can be set to a lower value to reduce latency.  If there are no latency sensitive cards in the system, but I/O intensive applications are being run, this can be increased to slightly improve performance.


    Plug and Play Configuration Sub-Menu

Configuration Mode

Use Setup Utility -- default

Use ICU

The Configuration Mode field is used to choose the method in which information about legacy ISA cards (ISA cards which do not have Plug and Play capabilities) is conveyed to the BIOS to allow the BIOS to set up PCI cards and ISA Plug and Play cards without conflicting with the legacy ISA cards.

If Use ICU is chosen, then the BIOS will depend upon information provided by run-time Plug and Play software (Configuration Manager and ISA Configuration Utility) to ensure that there are no conflicts with legacy ISA cards.  Only choose this method if your system is configured with these utilities and they are used. When Use ICU is chosen no other fields are displayed in this Sub-Menu.

If Use Setup Utility is chosen, then the BIOS will depend upon information provided by the user in the fields below to prevent conflicts between Plug and Play cards and legacy ISA cards.  If the Use Setup Utility is chosen, the user should not install and use run-time Plug and Play software (Configuration Manager and ICU).

ISA Shared Memory Size

Disabled -- default

16 KB

32 KB

48 KB

64 KB

The ISA Shared Memory Size field is used to define a block of system memory which will not be shadowed (shadowing is a technique which copies a block of memory from an add in card's ROM to the same address in  system memory to allow faster access to the code and achieve higher performance).  By default all upper memory is shadowed unless a block is un-shadowed using this and the ISA Shared Memory Base Address fields.

This field should be set to Disabled unless an ISA card is used which communicates with the CPU through a block of shared memory located in the upper memory area.  If set to a value other than Disabled  the ISA Shared Memory Base Address field will appear below.  Note that if a value of  64 KB is chosen, then the ISA Shared Memory Base Address field can only be set to D0000h or below.

ISA Shared Memory Base Address

C0000h

C4000h

C8000h

CC000h

D0000h

D4000h

D8000h

DC000h

The ISA Shared Memory Base Address field works in conjunction with the ISA Shared Memory Size.  See above.  This parameter is only displayed if the ISA Shared Memory Size parameter is not disabled.

IRQ 3*

IRQ 4*

IRQ 5

IRQ 7*

IRQ 9

IRQ 10

IRQ 11

IRQ 15*

Available

Used By ISA Card

* These options will not be visible if consumed by on-board resources (IRQ3 Serial Port 2, IRQ4 Serial Port 1, IRQ7 Parallel Port, IRQ 15, both IDE interfaces used).

The IRQ 3 - IRQ 15 fields are used to indicate whether individual interrupts are used by ISA legacy cards.  If not used, then they should be set to Available.  If used they should be set to Used By ISA Card.

Notes: All but one interrupt can be set to Used By ISA Card.  One must remain available for PCI cards which use interrupts to function.

On older systems that have the B stepping of the SIO PCI bridge component, only interrupts 9, 10 and 11 will show on this screen, even if additional interrupts are available.


    Security Menu

There are two types of passwords available, User Password and Administrative Password.  The User password can be used to control access to the Setup Utility, the keyboard upon initial boot, and the keyboard when used in conjunction with the Security Hot Key.  The Administrative Password is used to control access to the Setup Utility.  The following table describes the interaction between these passwords:

Password In Effect	Enter Setup with User Password	Enter Setup with Administrate Password	Boot
User Password Only	Can change all fields	N.A.	User Password Required
Administrative Password Only	N..A.	Can change all fields	No  Password Required
Both	Can change limited number of fields	Can change all fields	User or Administrative Password Required
If the Administrative Password is in effect and Setup is entered with the User Password only the following fields may be changed:

System Date

System Time

User Password

Security Hot Key

User Password is

Disabled -- default

Enabled

Administrative Password is

Disabled -- default

Enabled

The User Password is and Administrative Password is fields indicate whether the User and Administrative passwords have been set.  If neither the User Password is or the Administrative Password is fields are set to Enabled neither the Unattended Start or Security Hot Key (CTRL-ALT-) fields will be displayed.

Set User Password

When the Set User Password field is chosen the user is presented with one of two sub-menus.  If there is currently no User Password in effect the following menu appears:

Enter New Password_______

Confirm New Password_______

Press Enter or TAB to Accept

Press ESC to Abort

If there is already a User Password in effect, the following menu appears.  To disable the password, use a carriage return as the new password.

Press ESC to Abort

If there is already an Administrative Password in effect, the following menu appears.  To disable the password, use a carriage return as the new password.

Enter Current Password_______

Enter New Password_______

Confirm New Password_______

Press Enter or TAB to Accept

Press ESC to Abort

Unattended Start

Disabled -- default

Enabled

The Unattended Start  field controls the point at which the User Password is required.  If set to Disabled  the User Password is required before the system boots, either from disk or the network.  The user will be prompted for the password with the text string "Enter Password (1):"

If set to Enabled the system will go through automatic boot activity (for instance running CONFIG.SYS and AUTOEXEC.BAT when booting DOS from disk), however the keyboard will be locked and the User Password must be entered to unlock it.  The BIOS does not provide any prompt string so it is suggested that the last thing that the automatic login sequence does is prompt the user for the password.

The Unattended Start field can only be set if a User Password is in effect.

Security Hot Key (CTRL-ALT-)

Alpha-Numeric Key

The Security Hot Key (CTRL-ALT-) field can be used to define a key which when entered in conjunction with the CTRL and ALT keys puts the system into secure mode (locks the keyboard).  When this Hot Key combination is entered the Num Lock, Caps Lock, and Scroll Lock LEDs on the keyboard will flash on and off in sequence, indicating to the user that the system is in secure mode (as opposed to being hung).


    Exit Menu

Exit Saving Changes

The Exit Saving Changes field is used to exit the Setup Utility saving the current state of all parameters.

When the Enter key is entered the following sub-menu is displayed:

Exit Saving Changes?

Press Enter to Continue

Press ESC to Abort

If the Enter key is selected then the Setup Utility will be exited with all parameters set to their current values.  If the ESC key is selected, then the user is returned to the Exit menu without effecting any change.

Exit Discarding Changes

The Exit Discarding Changes field is used to exit the Setup Utility discarding any changes made to Setup parameters.  When the Enter key is entered the following sub-menu is displayed:

The Discard Changes field is used undo any changes made to Setup parameters during this Setup session.  When the Enter key is entered the following sub-menu is displayed:

Discard Changes?

Press Enter to Continue

Press ESC to Abort

If the Enter key is selected then any changes made to Setup parameters are discarded.  If the ESC key is selected, then the user is returned to the Exit menu without effecting any changes.


    Appendix D   for detailed descriptions of the setup options.


PCI Auto-configuration Capability

The PCI auto-configuration utility operates in conjunction with the system Setup utility to allow the insertion and removal of PCI cards to the system without user intervention. When the system is turned on after adding a PCI add-in card, the BIOS automatically configures interrupts, I/O space, and other parameters. The user does not have to configure jumpers or worry about potential resource conflicts. Because PCI cards use the same interrupt resources as ISA cards, the user must specify the interrupts used by ISA add-in cards in the Setup utility or use a Plug'n'Play Configuration Utility. The PCI Auto-Configuration function complies with version 2.0G of the PCI BIOS specification.


ISA Plug and Play Capability

The Premiere/PCI Expandable Desktop fully supports the ISA Plug and Play standard Version 1.1. This will allow auto-configuration of Plug and Play ISA cards, and resource management for legacy ISA cards, when used in conjunction with the ICU (ISA Configuration Utility). Copies of the IAL Plug and Play specification may be obtained via FaxBack (800) 628-2283, or via CompuServe by typing Go PlugPlay. System configuration data is stored in the on-board Flash device.


Security features

BIOS Password:  A BIOS password feature provides security during the boot process. A password can be entered using the Setup utility and must be re-entered prior to disk boot each time the system is reset. To enable, disable, or change the password, refer to the Setup program options in

The Hard Disk C: through Hard Disk F: fields report the presence of, and identification string reported by, up to 4 physical IDE drives (two each of PCI and ISA).  When the cursor is placed on one of these fields and it is selected by hitting the Enter Key, the Hard Disk Sub-Menu appears (see below) allowing parameters which affect the drives to be set.

Note:	Disk drive assignments

Drive letters will be assigned to physical drives as follows:

PCI IDE Interface Only

Master	C:
Secondary	D:

ISA Interface Only

Master	C:

When drives have multiple partitions on them, partitions beyond the primary partition will be assigned in ascending order, based on available drive letters and other installed drives.  Partitions are assigned to primary partitions first (across multiple drives), and then to secondary partitions.  This means that when there are multiple drives with multiple partitions, the logical drive numbering scheme may result in discontiguous logical partitions on the same physical drive.

For instance, if there is a "Drive 1" with two partitions which is a Master on the PCI IDE interface, a "Drive 2" with three partitions which is a Slave on the PCI interface, and a "Drive 3" with two partitions which is a master on the ISA interface the drive letters will be assigned as follows:

The Number of Cylinders, Number of Heads, and Number of Sectors  fields display what is reported by the drive if Hard Disk Type is set to Auto Configured.  If Hard Disk Type is set to User Definable then these fields are entered by the user. Hard Disk Type should be set to Auto Configured unless the drive was formatted on another system with parameters different than those reported by the drive.

Maximum Capacity

Value calculated from Cylinder, Head, and Sector info above

Initialization Timeout

Disabled

5 Seconds

10 Seconds -- default

31 Seconds

Initialization Timeout selects the number of seconds the BIOS will wait to determine if an IDE drive is present, after initiating a transaction with the drive.  If a drive is present and responds to the BIOS before the Initialization Timeout period, then the BIOS will proceed, i.e. there is no boot-time penalty for a large value when a drive is present.  If a drive is not present, then the BIOS will wait the Initialization Timeout period before proceeding.  If a drive is present, but does not respond to the BIOS within the Initialization Timeout range, then the BIOS will not see the drive and it will not be accessible.  This value should be set to Disabled for any IDE drives not installed.  This parameter works in conjunction with the Hard Disk Pre-Delay parameter contained in the Boot Options sub-menu of the Main menu.

IDE Translation Mode

Standard CHS -- default

Logical Block

Extended CHS

Auto Detected

The IDE Translation Mode parameter controls the way in which the BIOS interacts with the drive in terms of drive geometry.  Proper choice is dependent upon the drive's size, capabilities, and the operating system (OS) used.

Standard CHS is the translation mode that has been in use for years.  Its use limits IDE capacity to a maximum of 528 Megabytes regardless of the size of the drive used.

Logical Block mode overcomes the 528 MB maximum size limitation imposed by Standard CHS mode. It should be used only when the drive supports LBA (Logical Block Addressing), and the OS supports LBA, or uses the BIOS to access the disk.

Extended CHS mode also overcomes the 528 MB maximum size limitation imposed by Standard CHS mode.   It can be used with drives which are larger than 528 MB, but do not support LBA mode.

Auto Detected allows the BIOS to examine the drive and determine the optimal mode. The first choice is to utilize Logical Block  mode if it is supported by the drive. The second choice is to utilize Extended CHS   mode if the drive topology allows.  If neither of the above two methods are possible, then Standard CHS mode is used.   Important NOTE: When set to Auto Detected the BIOS will detect what the drive is capable of, not the translation mechanism which was used to format the drive.  If a drive is run in a mode other than the mode in which  it was partitioned and formatted, unpredictable results may occur, including data loss.

Different operating systems have different abilities regarding IDE Translation Modes:

UNIX operating systems (as currently implemented) do not support either LBA or ECHS and must utilize the Standard CHS method. UNIX can support drives larger than 528 MB, but does so in its own way.

OS/2 2.1 can support LBA, ECHS or Standard CHS methods . Note that LBA support may require a switch setting on an OS/2 driver in order to operate in that mode. (*)

OS/2 2.0 & Novell Netware can support either ECHS or Standard CHS methods, but not LBA.

DOS & Windows can support LBA, ECHS or Standard CHS methods. If the "Fast 32-bit IDE" option of Windows is utilized, make sure to use the  Standard CHS setting only, unless a version of WDCDRV.386 is being used which supports these advanced geometrys.  You will get better performance NOT using "Fast 32-bit IDE" if using a drive which employs Mode 3 PIO on the PCI interface, unless using a version of WDCDRV.386 which supports these advanced modes.

Multiple Sector Setting

Disabled

4 Sectors/Block

8 Sectors/Block

Auto Detected -- default

The Multiple Sector Setting  field controls the number of sectors which are transferred by an IDE drive per interrupt generated.  If set to Disabled, then an interrupt will be generated for each sector transferred, even if the OS issues a multi-sector transfer.  If set to 4 Sectors/Block or 8 Sectors/Block then 4 or 8 sectors will be transferred per interrupt (for a request that is as large as, or larger than 4 or 8 sectors).  If Auto Detected is chosen, then x sectors will be transferred per interrupt, where x is the maximum value supported by the drive.  If a drive does not support multiple sectors/block then the BIOS will ignore this setting.  If the drive does not support the specific number (4 or 8) of sectors chosen, then the BIOS will default to the largest number of sectors the drive supports that are smaller than the chosen value.

Fast Programmed I/O Modes

Disabled

Auto Detected -- default

The Fast Programmed I/O Modes field controls the speed in which Programmed I/O (PIO) transfers occur on the PCI IDE interface.  If set to Disabled, transfers occur at an un-optimized (Mode 0) speed.  If set to Auto Detected, transfers occur at the rate which the drive reports as its maximum (up to and including the maximum mode 3 timing).  This field should only be set to Disabled if a drive is being used which incorrectly reports an ability to function with advanced timings.


    Language

English (US)

..

..

The Language: field controls the language of the text strings used in Setup and the BIOS.  Any installed language will appear as an option in its own language (for example, German will appear as Deutch).  Only installed languages will appear as options.  Language may be installed using the FMUP utility and the appropriate .LNG file.


    Boot Options Sub-Menu

When the cursor is placed the Boot Options: field and it is selected by hitting the Enter Key, the Boot Options Sub-Menu appears allowing parameters which affect the boot process to be set.

Boot Sequence

C: First, Then A:

A: First, Then C: -- default

C: Only

A: Only

The field controls the order in which the BIOS attempts to boot from the hard and floppy drives.

System Cache

Disabled

Enabled -- default

The System Cache field controls both the primary and secondary caches. Setting System Cache Disabled to will hurt performance, but might be required when running software which utilizes software timing loops and needs to be slowed down to execute properly.

Boot Speed

Turbo -- default

De-turbo

The Boot Speed field controls the system CPU cycles.  De-turbo mode slows the CPU by disabling system cache and adding increased refresh cycles.  It does not reduce CPU speed to 4.77Mhz or 8Mhz AT class machines.

Num Lock

Off -- default

On

The Num Lock field controls whether the keyboard Num Lock function is turned on or off when the system is booted.

Setup Prompt

Disabled

Enabled -- default

The Setup Prompt field controls whether the "Press <F1> Key To Enter Setup" message is displayed during POST (Power On Self Test).It does not control access, just the message.

Hard Disk Pre-Delay

Disabled

1 Second

2 Seconds

3 Seconds -- default

4 Seconds

5 Seconds

6 Seconds

7 Seconds

The Hard Disk Pre-Delay provides a mechanism which delays the BIOS's attempt to initialize the first  IDE drive in the system.  It is necessary because certain drives take longer than others to "spin up" and might hang if they are accessed too soon after being powered up or reset.  The delay is only honored for the first drive accessed. This parameter works in conjunction with the Initialization Timeout parameter contained in the Hard Disk Sub-menu of the Main menu.  The two are added together.

It should be noted that this new addition to the BIOS Setup is the result of our speeding up the POST process.

Typematic Rate Programming

Default -- default

Override

The parameter controls whether default or user configurable values are used for Typematic Rate Delay and Typematic Rate (see below).  If Default is chosen then Typematic Rate Delay is set to 500 msec and Typematic Rate is set to 15.  If Override is chosen the following two parameters appear, allowing the user to customize these values.

Typematic Rate Delay

250 msec -- default

500 msec

750 msec

1000 msec

The Typematic Rate Delay field controls how long it takes for the keyboard auto-repeat function to start when a keyboard key is held down.

Typematic Rate

6 char/sec -- default

8 char/sec

10 char/sec

12 char/sec

15 char/sec

20 char/sec

24 char/sec

30 char/sec

The Typematic Rate field controls the speed characters repeat when you hold down a keyboard key.  The higher the number, the faster the repeat.

Video Mode

The Video Mode  field is informative only.

Mouse

The Mouse  field is informative only.  If a PS/2 style mouse is installed, this field will display "Installed".  If the system does not support a PS/2 style mouse, or if it does and the mouse is not installed, this field will display "Not Installed".

    Peripheral Configuration Sub-Menu

Configuration Mode

 	Auto -- default

Manual

The Configuration Mode fields controls whether on board resources are manually or automatically set up.  When set to Auto, on board  system peripherals (IDE drives, Floppy Drive, Serial Ports, Parallel Port) are automatically configured during power up.  When set to Manual, system peripherals must be explicitly configured.  The following 6 fields (PCI IDE Interface to Parallel Port Address) are only user accessible when Configuration Mode is set to Manual.

PCI IDE Interface

 	Enabled -- default

Disabled

Standard ISA IDE Interface

Enabled -- default

Disabled

Floppy Interface

Enabled -- default

Disabled

The PCI IDE Interface, Standard IDE Interface, and Floppy Interface  fields allow these drive interfaces to be individually enabled or disabled.

Serial Port 1 Address

Disabled

COM1, 3F8h -- default

COM2, 2F8h

COM3, 3E8h

COM4, 2E8h

Serial Port 2 Address

Disabled

COM1, 3F8h

COM2, 2F8h -- default

COM3, 3E8h

COM4, 2E8h

The Serial Port 1 Address, Serial Port 2 Address fields allow the user to select the I/O ports used by these interfaces.  If a COM port is chosen for one of the Serial Port Addresses, it will not appear in the option list for the other Serial Port Address, i.e. if one of the Serial Port Addresses is set to Disabled, then there will be four choices for the other serial port address.  Otherwise there will be three choices.

Parallel Port Address

Disabled

LPT3, 3BCh

LPT1, 378h -- default

LPT2, 278h

The Parallel Port Address fields allow the user to select the I/O ports used by these interfaces.

Parallel Port Mode

Compatible -- default

Extended

When set to Compatible, the parallel port will be set up in a mode compatible with the original AT.  When set to Extended the parallel port will be set up in the most advanced mode allowed by the chipset (ex. ECC, ECP).

Serial Port 1 IRQ

Interrupt Used

Serial Port 2 IRQ

Interrupt Used

Parallel Port IRQ

Interrupt Used

The Serial Port 1 IRQ, , Serial Port 2 IRQ and Parallel Port IRQ  fields display the interrupts used by the Serial and Parallel Ports.  These values may not be changed by the user.  If an interface is disabled via the Serial Port 1 Address, Serial Port 2 Address, or Parallel Port Address fields, then the associated interrupt is not displayed, and is available for use by add in cards.


    Advanced Chipset Configuration Sub-Menu

Base Memory Size

512KB

640 KB -- default

The Base Memory Size field controls the mapping of addresses between 512K and 640K (80000h-9FFFFh).  If 512KB is chosen then accesses between 512K and 640K are directed to the ISA bus.  When 640 KB is selected accesses between 512K and 640K are directed to system DRAM.  Unless using an ISA card which requires access to this particular address range this field should be set to 640 KB.

ISA Bus Speed

Compatible -- default

Enhanced

The ISA Bus Speed field controls the speed of the ISA Bus clock.  If set to Compatible the speed will fall within the limits defined by the IBM AT Technical Reference (6-8.33 Mhz).  If set to Enhanced the speed will be greater than the maximum defined by the IBM AT Technical Reference manual.  Modern ISA cards can operate with the enhanced speeds,  however some older cards can experience difficulties.  ISA performance will be enhanced when ISA Bus Speed is set to enhanced.   The actual value of the Bus Clock when set to Compatible or Enhanced is dependent upon the external frequency of the CPU:

External Frequency	Compatible	Enhanced
60 Mhz	7.5 Mhz	10 Mhz
66 Mhz	8.25 Mhz	11 Mhz
Byte Merging

Enabled

Disabled -- default

Byte Merging is a feature which increases performance for older applications which write to video memory in bytes instead of words.  However, this feature is not supported on all PCI video cards.  For best performance this field should be enabled unless a PCI graphics card which does not support this feature is used.  If this field is enabled and used with a card which lacks support video corruption will be seen in some video modes.

PCI IDE Prefetch Buffers

Enabled -- default

Disabled

This field is used to disable a set of prefetch buffers in the PCI IDE controller.  Disabling the buffers may be required when using Operating Systems (such as NT and OS/2) which do not use the BIOS to access the hard and do not disable interrupts when completing a programmed I/O operation.  Setting PCI IDE Prefetch Buffers to Disabled has negative performance implications.  Some operating systems may provide a patch to correct this problem, contact the operating system vendor for details.  A second work around is to disable the PCI IDE interface and use the ISA IDE interface only.

ISA LFB Size

Disabled -- default

1 MB

3 MB

7 MB

The ISA Video Linear Frame Buffer Size provides a mechanism for creating a hole in the system memory map.  Accesses made to addresses within this hole will be directed to the ISA bus instead of main memory.  This should be set to Disabled  unless you are using an ISA video card with a linear frame buffer or other ISA cards which require greater than 64K of memory and you are not using the Plug and Play run-time utilities (Configuration Manager & ISA Configuration Utility).

ISA LFB Base Address

Dependent upon ISA LFB Size

If	ISA LFB Size	Then	ISA  LFB Base Address
	Disabled		N.A.
	1 MB`		15 MB
	3 MB		13 MB
	7 MB		9   MB
The ISA Video LFB Base Address field displays the starting address of the ISA memory hole if a value other than Disabled is chosen for the ISA Video LFB Size parameter.  If  ISA Video LFB Size is set to disabled, then this field does not appear.  This field is informative only, i.e. it cannot be changed by the user.

Video Palette Snoop

Disabled -- default

Enabled

The Video Palette Snoop field controls the ability of a PCI graphics cards to "snoop" write cycles to an ISA video card's color palette registers.  This should normally be set to Disabled.  It should only be set to Enabled if:

An ISA card connects to a PCI graphics card via the VESA connector

AND that ISA card connects to a color monitor.

Note: This field will not show up if using the B stepping of a Cirrus 5434 graphics controller.

Latency Timer (PCI Clocks)

Number between 0 and 256

66 -- default

The Latency Timer (PCI Clocks) field controls the length of time an agent on the PCI bus can hold the bus when another agent has requested the bus.  Its default value is 66.  In general this should not be changed.  If there are latency sensitive cards in the system (such as audio cards and/or network cards with small buffers) this can be set to a lower value to reduce latency.  If there are no latency sensitive cards in the system, but I/O intensive applications are being run, this can be increased to slightly improve performance.


    Plug and Play Configuration Sub-Menu

Configuration Mode

Use Setup Utility -- default

Use ICU

The Configuration Mode field is used to choose the method in which information about legacy ISA cards (ISA cards which do not have Plug and Play capabilities) is conveyed to the BIOS to allow the BIOS to set up PCI cards and ISA Plug and Play cards without conflicting with the legacy ISA cards.

If Use ICU is chosen, then the BIOS will depend upon information provided by run-time Plug and Play software (Configuration Manager and ISA Configuration Utility) to ensure that there are no conflicts with legacy ISA cards.  Only choose this method if your system is configured with these utilities and they are used. When Use ICU is chosen no other fields are displayed in this Sub-Menu.

If Use Setup Utility is chosen, then the BIOS will depend upon information provided by the user in the fields below to prevent conflicts between Plug and Play cards and legacy ISA cards.  If the Use Setup Utility is chosen, the user should not install and use run-time Plug and Play software (Configuration Manager and ICU).

ISA Shared Memory Size

Disabled -- default

16 KB

32 KB

48 KB

64 KB

The ISA Shared Memory Size field is used to define a block of system memory which will not be shadowed (shadowing is a technique which copies a block of memory from an add in card's ROM to the same address in  system memory to allow faster access to the code and achieve higher performance).  By default all upper memory is shadowed unless a block is un-shadowed using this and the ISA Shared Memory Base Address fields.

This field should be set to Disabled unless an ISA card is used which communicates with the CPU through a block of shared memory located in the upper memory area.  If set to a value other than Disabled  the ISA Shared Memory Base Address field will appear below.  Note that if a value of  64 KB is chosen, then the ISA Shared Memory Base Address field can only be set to D0000h or below.

ISA Shared Memory Base Address

C0000h

C4000h

C8000h

CC000h

D0000h

D4000h

D8000h

DC000h

The ISA Shared Memory Base Address field works in conjunction with the ISA Shared Memory Size.  See above.  This parameter is only displayed if the ISA Shared Memory Size parameter is not disabled.

IRQ 3*

IRQ 4*

IRQ 5

IRQ 7*

IRQ 9

IRQ 10

IRQ 11

IRQ 15*

Available

Used By ISA Card

* These options will not be visible if consumed by on-board resources (IRQ3 Serial Port 2, IRQ4 Serial Port 1, IRQ7 Parallel Port, IRQ 15, both IDE interfaces used).

The IRQ 3 - IRQ 15 fields are used to indicate whether individual interrupts are used by ISA legacy cards.  If not used, then they should be set to Available.  If used they should be set to Used By ISA Card.

Notes: All but one interrupt can be set to Used By ISA Card.  One must remain available for PCI cards which use interrupts to function.

On older systems that have the B stepping of the SIO PCI bridge component, only interrupts 9, 10 and 11 will show on this screen, even if additional interrupts are available.


    Security Menu

There are two types of passwords available, User Password and Administrative Password.  The User password can be used to control access to the Setup Utility, the keyboard upon initial boot, and the keyboard when used in conjunction with the Security Hot Key.  The Administrative Password is used to control access to the Setup Utility.  The following table describes the interaction between these passwords:

Password In Effect	Enter Setup with User Password	Enter Setup with Administrate Password	Boot
User Password Only	Can change all fields	N.A.	User Password Required
Administrative Password Only	N..A.	Can change all fields	No  Password Required
Both	Can change limited number of fields	Can change all fields	User or Administrative Password Required
If the Administrative Password is in effect and Setup is entered with the User Password only the following fields may be changed:

System Date

System Time

User Password

Security Hot Key

User Password is

Disabled -- default

Enabled

Administrative Password is

Disabled -- default

Enabled

The User Password is and Administrative Password is fields indicate whether the User and Administrative passwords have been set.  If neither the User Password is or the Administrative Password is fields are set to Enabled neither the Unattended Start or Security Hot Key (CTRL-ALT-) fields will be displayed.

Set User Password

When the Set User Password field is chosen the user is presented with one of two sub-menus.  If there is currently no User Password in effect the following menu appears:

Enter New Password_______

Confirm New Password_______

Press Enter or TAB to Accept

Press ESC to Abort

If there is already a User Password in effect, the following menu appears.  To disable the password, use a carriage return as the new password.

Enter Current Password_______

Press ESC to Abort

If there is already an Administrative Password in effect, the following menu appears.  To disable the password, use a carriage return as the new password.

Enter Current Password_______

Enter New Password_______

Confirm New Password_______

Press Enter or TAB to Accept

Press ESC to Abort

Unattended Start

Disabled -- default

Enabled

The Unattended Start  field controls the point at which the User Password is required.  If set to Disabled  the User Password is required before the system boots, either from disk or the network.  The user will be prompted for the password with the text string "Enter Password (1):"

If set to Enabled the system will go through automatic boot activity (for instance running CONFIG.SYS and AUTOEXEC.BAT when booting DOS from disk), however the keyboard will be locked and the User Password must be entered to unlock it.  The BIOS does not provide any prompt string so it is suggested that the last thing that the automatic login sequence does is prompt the user for the password.

The Unattended Start field can only be set if a User Password is in effect.

Security Hot Key (CTRL-ALT-)

Alpha-Numeric Key

The Security Hot Key (CTRL-ALT-) field can be used to define a key which when entered in conjunction with the CTRL and ALT keys puts the system into secure mode (locks the keyboard).  When this Hot Key combination is entered the Num Lock, Caps Lock, and Scroll Lock LEDs on the keyboard will flash on and off in sequence, indicating to the user that the system is in secure mode (as opposed to being hung).

Technical Product Summary - BOARD Level Features - CPU
CPU

The original motherboard supported only 60 MHz Pentium processors and did not include the voltage regulation circuitry.


SECOND LEVEL CACHE

The second-level cache operated in write-through mode rather than write-back.


REAL TIME CLOCK

The Dallas DS12887 was socketed and could be replaced by the user, if necessary.


BIOS

The BIOS version number ends end .AF1 rather than .AF2.  Also, the CMOS setup utility uses the earlier version of the user interface.  Parameters and options will not necessarily be the same.


IDE

PCI IDE was not integrated on the original Premiere/PCI product. Instead, a PCI IDE paddle card was used in PCI slot 3 (J10C2, the PCI slot closest to the 3.3V connector) and made use of some of the reserved pins on the PCI interface, as listed in the following table:

Identification string returned from drive

Not Installed

The Hard Disk C: through Hard Disk F: fields report the presence of, and identification string reported by, up to 4 physical IDE drives (two each of PCI and ISA).  When the cursor is placed on one of these fields and it is selected by hitting the Enter Key, the Hard Disk Sub-Menu appears (see below) allowing parameters which affect the drives to be set.

Note:	Disk drive assignments

Drive letters will be assigned to physical drives as follows:

PCI IDE Interface Only

Master	C:
Secondary	D:

ISA Interface Only

Master	C:
Secondary	D:

ISA & PCI IDE Interface Two Drives Used

When drives have multiple partitions on them, partitions beyond the primary partition will be assigned in ascending order, based on available drive letters and other installed drives.  Partitions are assigned to primary partitions first (across multiple drives), and then to secondary partitions.  This means that when there are multiple drives with multiple partitions, the logical drive numbering scheme may result in discontiguous logical partitions on the same physical drive.

For instance, if there is a "Drive 1" with two partitions which is a Master on the PCI IDE interface, a "Drive 2" with three partitions which is a Slave on the PCI interface, and a "Drive 3" with two partitions which is a master on the ISA interface the drive letters will be assigned as follows:

    Hard Disk Sub-Menu

Hard Disk Type

Auto Configured -- default

User Definable

Number of Cylinders

Number of Heads

Number of Sectors

If	Hard Disk Type = Auto Configured

Then parameters reported by drive

If	Hard Disk Type = User Definable

Then parameters entered by user

The Number of Cylinders, Number of Heads, and Number of Sectors  fields display what is reported by the drive if Hard Disk Type is set to Auto Configured.  If Hard Disk Type is set to User Definable then these fields are entered by the user. Hard Disk Type should be set to Auto Configured unless the drive was formatted on another system with parameters different than those reported by the drive.

Maximum Capacity

Value calculated from Cylinder, Head, and Sector info above

Initialization Timeout

Disabled

5 Seconds

10 Seconds -- default

31 Seconds

Initialization Timeout selects the number of seconds the BIOS will wait to determine if an IDE drive is present, after initiating a transaction with the drive.  If a drive is present and responds to the BIOS before the Initialization Timeout period, then the BIOS will proceed, i.e. there is no boot-time penalty for a large value when a drive is present.  If a drive is not present, then the BIOS will wait the Initialization Timeout period before proceeding.  If a drive is present, but does not respond to the BIOS within the Initialization Timeout range, then the BIOS will not see the drive and it will not be accessible.  This value should be set to Disabled for any IDE drives not installed.  This parameter works in conjunction with the Hard Disk Pre-Delay parameter contained in the Boot Options sub-menu of the Main menu.

IDE Translation Mode

Standard CHS -- default

Logical Block

Extended CHS

Auto Detected

The IDE Translation Mode parameter controls the way in which the BIOS interacts with the drive in terms of drive geometry.  Proper choice is dependent upon the drive's size, capabilities, and the operating system (OS) used.

Standard CHS is the translation mode that has been in use for years.  Its use limits IDE capacity to a maximum of 528 Megabytes regardless of the size of the drive used.

Logical Block mode overcomes the 528 MB maximum size limitation imposed by Standard CHS mode. It should be used only when the drive supports LBA (Logical Block Addressing), and the OS supports LBA, or uses the BIOS to access the disk.

Extended CHS mode also overcomes the 528 MB maximum size limitation imposed by Standard CHS mode.   It can be used with drives which are larger than 528 MB, but do not support LBA mode.

Auto Detected allows the BIOS to examine the drive and determine the optimal mode. The first choice is to utilize Logical Block  mode if it is supported by the drive. The second choice is to utilize Extended CHS   mode if the drive topology allows.  If neither of the above two methods are possible, then Standard CHS mode is used.   Important NOTE: When set to Auto Detected the BIOS will detect what the drive is capable of, not the translation mechanism which was used to format the drive.  If a drive is run in a mode other than the mode in which  it was partitioned and formatted, unpredictable results may occur, including data loss.

Different operating systems have different abilities regarding IDE Translation Modes:

UNIX operating systems (as currently implemented) do not support either LBA or ECHS and must utilize the Standard CHS method. UNIX can support drives larger than 528 MB, but does so in its own way.

OS/2 2.1 can support LBA, ECHS or Standard CHS methods . Note that LBA support may require a switch setting on an OS/2 driver in order to operate in that mode. (*)

OS/2 2.0 & Novell Netware can support either ECHS or Standard CHS methods, but not LBA.

DOS & Windows can support LBA, ECHS or Standard CHS methods. If the "Fast 32-bit IDE" option of Windows is utilized, make sure to use the  Standard CHS setting only, unless a version of WDCDRV.386 is being used which supports these advanced geometrys.  You will get better performance NOT using "Fast 32-bit IDE" if using a drive which employs Mode 3 PIO on the PCI interface, unless using a version of WDCDRV.386 which supports these advanced modes.

Multiple Sector Setting

Disabled

4 Sectors/Block

8 Sectors/Block

Auto Detected -- default

The Multiple Sector Setting  field controls the number of sectors which are transferred by an IDE drive per interrupt generated.  If set to Disabled, then an interrupt will be generated for each sector transferred, even if the OS issues a multi-sector transfer.  If set to 4 Sectors/Block or 8 Sectors/Block then 4 or 8 sectors will be transferred per interrupt (for a request that is as large as, or larger than 4 or 8 sectors).  If Auto Detected is chosen, then x sectors will be transferred per interrupt, where x is the maximum value supported by the drive.  If a drive does not support multiple sectors/block then the BIOS will ignore this setting.  If the drive does not support the specific number (4 or 8) of sectors chosen, then the BIOS will default to the largest number of sectors the drive supports that are smaller than the chosen value.

Fast Programmed I/O Modes

Disabled

Auto Detected -- default

The Fast Programmed I/O Modes field controls the speed in which Programmed I/O (PIO) transfers occur on the PCI IDE interface.  If set to Disabled, transfers occur at an un-optimized (Mode 0) speed.  If set to Auto Detected, transfers occur at the rate which the drive reports as its maximum (up to and including the maximum mode 3 timing).  This field should only be set to Disabled if a drive is being used which incorrectly reports an ability to function with advanced timings.


    Language

English (US)

..

..

The Language: field controls the language of the text strings used in Setup and the BIOS.  Any installed language will appear as an option in its own language (for example, German will appear as Deutch).  Only installed languages will appear as options.  Language may be installed using the FMUP utility and the appropriate .LNG file.


    Boot Options Sub-Menu

When the cursor is placed the Boot Options: field and it is selected by hitting the Enter Key, the Boot Options Sub-Menu appears allowing parameters which affect the boot process to be set.

Boot Sequence

C: First, Then A:

A: First, Then C: -- default

C: Only

A: Only

The field controls the order in which the BIOS attempts to boot from the hard and floppy drives.

System Cache

Disabled

Enabled -- default

The System Cache field controls both the primary and secondary caches. Setting System Cache Disabled to will hurt performance, but might be required when running software which utilizes software timing loops and needs to be slowed down to execute properly.

Boot Speed

Turbo -- default

De-turbo

The Boot Speed field controls the system CPU cycles.  De-turbo mode slows the CPU by disabling system cache and adding increased refresh cycles.  It does not reduce CPU speed to 4.77Mhz or 8Mhz AT class machines.

Num Lock

Off -- default

On

The Num Lock field controls whether the keyboard Num Lock function is turned on or off when the system is booted.

Setup Prompt

Disabled

Enabled -- default

The Setup Prompt field controls whether the "Press <F1> Key To Enter Setup" message is displayed during POST (Power On Self Test).It does not control access, just the message.

Hard Disk Pre-Delay

Disabled

1 Second

2 Seconds

3 Seconds -- default

4 Seconds

5 Seconds

6 Seconds

7 Seconds

The Hard Disk Pre-Delay provides a mechanism which delays the BIOS's attempt to initialize the first  IDE drive in the system.  It is necessary because certain drives take longer than others to "spin up" and might hang if they are accessed too soon after being powered up or reset.  The delay is only honored for the first drive accessed. This parameter works in conjunction with the Initialization Timeout parameter contained in the Hard Disk Sub-menu of the Main menu.  The two are added together.

It should be noted that this new addition to the BIOS Setup is the result of our speeding up the POST process.

Typematic Rate Programming

Default -- default

Override

The parameter controls whether default or user configurable values are used for Typematic Rate Delay and Typematic Rate (see below).  If Default is chosen then Typematic Rate Delay is set to 500 msec and Typematic Rate is set to 15.  If Override is chosen the following two parameters appear, allowing the user to customize these values.

Typematic Rate Delay

250 msec -- default

500 msec

750 msec

1000 msec

The Typematic Rate Delay field controls how long it takes for the keyboard auto-repeat function to start when a keyboard key is held down.

Typematic Rate

6 char/sec -- default

8 char/sec

10 char/sec

12 char/sec

15 char/sec

20 char/sec

24 char/sec

30 char/sec

The Typematic Rate field controls the speed characters repeat when you hold down a keyboard key.  The higher the number, the faster the repeat.

Video Mode

The Video Mode  field is informative only.

Mouse

The Mouse  field is informative only.  If a PS/2 style mouse is installed, this field will display "Installed".  If the system does not support a PS/2 style mouse, or if it does and the mouse is not installed, this field will display "Not Installed".

    Peripheral Configuration Sub-Menu

Configuration Mode

 	Auto -- default

Manual

The Configuration Mode fields controls whether on board resources are manually or automatically set up.  When set to Auto, on board  system peripherals (IDE drives, Floppy Drive, Serial Ports, Parallel Port) are automatically configured during power up.  When set to Manual, system peripherals must be explicitly configured.  The following 6 fields (PCI IDE Interface to Parallel Port Address) are only user accessible when Configuration Mode is set to Manual.

PCI IDE Interface

 	Enabled -- default

Disabled

Standard ISA IDE Interface

Enabled -- default

Disabled

Floppy Interface

Enabled -- default

Disabled

The PCI IDE Interface, Standard IDE Interface, and Floppy Interface  fields allow these drive interfaces to be individually enabled or disabled.

Serial Port 1 Address

Disabled

COM1, 3F8h -- default

COM2, 2F8h

COM3, 3E8h

COM4, 2E8h

Serial Port 2 Address

Disabled

COM1, 3F8h

COM2, 2F8h -- default

COM3, 3E8h

COM4, 2E8h

The Serial Port 1 Address, Serial Port 2 Address fields allow the user to select the I/O ports used by these interfaces.  If a COM port is chosen for one of the Serial Port Addresses, it will not appear in the option list for the other Serial Port Address, i.e. if one of the Serial Port Addresses is set to Disabled, then there will be four choices for the other serial port address.  Otherwise there will be three choices.

Parallel Port Address

Disabled

LPT3, 3BCh

LPT1, 378h -- default

LPT2, 278h

The Parallel Port Address fields allow the user to select the I/O ports used by these interfaces.

Parallel Port Mode

Compatible -- default

Extended

When set to Compatible, the parallel port will be set up in a mode compatible with the original AT.  When set to Extended the parallel port will be set up in the most advanced mode allowed by the chipset (ex. ECC, ECP).

Serial Port 1 IRQ

Interrupt Used

Serial Port 2 IRQ

Interrupt Used

Parallel Port IRQ

Interrupt Used

The Serial Port 1 IRQ, , Serial Port 2 IRQ and Parallel Port IRQ  fields display the interrupts used by the Serial and Parallel Ports.  These values may not be changed by the user.  If an interface is disabled via the Serial Port 1 Address, Serial Port 2 Address, or Parallel Port Address fields, then the associated interrupt is not displayed, and is available for use by add in cards.


    Advanced Chipset Configuration Sub-Menu

Base Memory Size

512KB

640 KB -- default

The Base Memory Size field controls the mapping of addresses between 512K and 640K (80000h-9FFFFh).  If 512KB is chosen then accesses between 512K and 640K are directed to the ISA bus.  When 640 KB is selected accesses between 512K and 640K are directed to system DRAM.  Unless using an ISA card which requires access to this particular address range this field should be set to 640 KB.

ISA Bus Speed

Compatible -- default

Enhanced

The ISA Bus Speed field controls the speed of the ISA Bus clock.  If set to Compatible the speed will fall within the limits defined by the IBM AT Technical Reference (6-8.33 Mhz).  If set to Enhanced the speed will be greater than the maximum defined by the IBM AT Technical Reference manual.  Modern ISA cards can operate with the enhanced speeds,  however some older cards can experience difficulties.  ISA performance will be enhanced when ISA Bus Speed is set to enhanced.   The actual value of the Bus Clock when set to Compatible or Enhanced is dependent upon the external frequency of the CPU:

External Frequency	Compatible	Enhanced
60 Mhz	7.5 Mhz	10 Mhz
66 Mhz	8.25 Mhz	11 Mhz
Byte Merging

Enabled

Disabled -- default

Byte Merging is a feature which increases performance for older applications which write to video memory in bytes instead of words.  However, this feature is not supported on all PCI video cards.  For best performance this field should be enabled unless a PCI graphics card which does not support this feature is used.  If this field is enabled and used with a card which lacks support video corruption will be seen in some video modes.

PCI IDE Prefetch Buffers

Enabled -- default

Disabled

This field is used to disable a set of prefetch buffers in the PCI IDE controller.  Disabling the buffers may be required when using Operating Systems (such as NT and OS/2) which do not use the BIOS to access the hard and do not disable interrupts when completing a programmed I/O operation.  Setting PCI IDE Prefetch Buffers to Disabled has negative performance implications.  Some operating systems may provide a patch to correct this problem, contact the operating system vendor for details.  A second work around is to disable the PCI IDE interface and use the ISA IDE interface only.

ISA LFB Size

Disabled -- default

1 MB

3 MB

7 MB

The ISA Video Linear Frame Buffer Size provides a mechanism for creating a hole in the system memory map.  Accesses made to addresses within this hole will be directed to the ISA bus instead of main memory.  This should be set to Disabled  unless you are using an ISA video card with a linear frame buffer or other ISA cards which require greater than 64K of memory and you are not using the Plug and Play run-time utilities (Configuration Manager & ISA Configuration Utility).

ISA LFB Base Address

Dependent upon ISA LFB Size

If	ISA LFB Size	Then	ISA  LFB Base Address
	Disabled		N.A.
	1 MB`		15 MB
	3 MB		13 MB
	7 MB		9   MB
The ISA Video LFB Base Address field displays the starting address of the ISA memory hole if a value other than Disabled is chosen for the ISA Video LFB Size parameter.  If  ISA Video LFB Size is set to disabled, then this field does not appear.  This field is informative only, i.e. it cannot be changed by the user.

Video Palette Snoop

Disabled -- default

Enabled

The Video Palette Snoop field controls the ability of a PCI graphics cards to "snoop" write cycles to an ISA video card's color palette registers.  This should normally be set to Disabled.  It should only be set to Enabled if:

An ISA card connects to a PCI graphics card via the VESA connector

AND that ISA card connects to a color monitor.

Note: This field will not show up if using the B stepping of a Cirrus 5434 graphics controller.

Latency Timer (PCI Clocks)

Number between 0 and 256

66 -- default

The Latency Timer (PCI Clocks) field controls the length of time an agent on the PCI bus can hold the bus when another agent has requested the bus.  Its default value is 66.  In general this should not be changed.  If there are latency sensitive cards in the system (such as audio cards and/or network cards with small buffers) this can be set to a lower value to reduce latency.  If there are no latency sensitive cards in the system, but I/O intensive applications are being run, this can be increased to slightly improve performance.


    Plug and Play Configuration Sub-Menu

Configuration Mode

Use Setup Utility -- default

Use ICU

The Configuration Mode field is used to choose the method in which information about legacy ISA cards (ISA cards which do not have Plug and Play capabilities) is conveyed to the BIOS to allow the BIOS to set up PCI cards and ISA Plug and Play cards without conflicting with the legacy ISA cards.

If Use ICU is chosen, then the BIOS will depend upon information provided by run-time Plug and Play software (Configuration Manager and ISA Configuration Utility) to ensure that there are no conflicts with legacy ISA cards.  Only choose this method if your system is configured with these utilities and they are used. When Use ICU is chosen no other fields are displayed in this Sub-Menu.

If Use Setup Utility is chosen, then the BIOS will depend upon information provided by the user in the fields below to prevent conflicts between Plug and Play cards and legacy ISA cards.  If the Use Setup Utility is chosen, the user should not install and use run-time Plug and Play software (Configuration Manager and ICU).

ISA Shared Memory Size

Disabled -- default

16 KB

32 KB

48 KB

64 KB

The ISA Shared Memory Size field is used to define a block of system memory which will not be shadowed (shadowing is a technique which copies a block of memory from an add in card's ROM to the same address in  system memory to allow faster access to the code and achieve higher performance).  By default all upper memory is shadowed unless a block is un-shadowed using this and the ISA Shared Memory Base Address fields.

This field should be set to Disabled unless an ISA card is used which communicates with the CPU through a block of shared memory located in the upper memory area.  If set to a value other than Disabled  the ISA Shared Memory Base Address field will appear below.  Note that if a value of  64 KB is chosen, then the ISA Shared Memory Base Address field can only be set to D0000h or below.

ISA Shared Memory Base Address

C0000h

C4000h

C8000h

CC000h

D0000h

D4000h

D8000h

DC000h

The ISA Shared Memory Base Address field works in conjunction with the ISA Shared Memory Size.  See above.  This parameter is only displayed if the ISA Shared Memory Size parameter is not disabled.

IRQ 3*

IRQ 4*

IRQ 5

IRQ 7*

IRQ 9

IRQ 10

IRQ 11

IRQ 15*

Available

Used By ISA Card

* These options will not be visible if consumed by on-board resources (IRQ3 Serial Port 2, IRQ4 Serial Port 1, IRQ7 Parallel Port, IRQ 15, both IDE interfaces used).

The IRQ 3 - IRQ 15 fields are used to indicate whether individual interrupts are used by ISA legacy cards.  If not used, then they should be set to Available.  If used they should be set to Used By ISA Card.

Notes: All but one interrupt can be set to Used By ISA Card.  One must remain available for PCI cards which use interrupts to function.

On older systems that have the B stepping of the SIO PCI bridge component, only interrupts 9, 10 and 11 will show on this screen, even if additional interrupts are available.


    Security Menu

There are two types of passwords available, User Password and Administrative Password.  The User password can be used to control access to the Setup Utility, the keyboard upon initial boot, and the keyboard when used in conjunction with the Security Hot Key.  The Administrative Password is used to control access to the Setup Utility.  The following table describes the interaction between these passwords:

Password In Effect	Enter Setup with User Password	Enter Setup with Administrate Password	Boot
User Password Only	Can change all fields	N.A.	User Password Required
Administrative Password Only	N..A.	Can change all fields	No  Password Required
Both	Can change limited number of fields	Can change all fields	User or Administrative Password Required
If the Administrative Password is in effect and Setup is entered with the User Password only the following fields may be changed:

System Date

System Time

User Password

Security Hot Key

User Password is

Disabled -- default

Enabled

Administrative Password is

Disabled -- default

Enabled

The User Password is and Administrative Password is fields indicate whether the User and Administrative passwords have been set.  If neither the User Password is or the Administrative Password is fields are set to Enabled neither the Unattended Start or Security Hot Key (CTRL-ALT-) fields will be displayed.

Set User Password

When the Set User Password field is chosen the user is presented with one of two sub-menus.  If there is currently no User Password in effect the following menu appears:

Enter New Password_______

Confirm New Password_______

Press Enter or TAB to Accept

Press ESC to Abort

If there is already a User Password in effect, the following menu appears.  To disable the password, use a carriage return as the new password.

Enter Current Password_______

Enter New Password_______

Confirm New Password_______

Press Enter or TAB to Accept

Press ESC to Abort

Set Administrative Password

When the Set Administrative Password field is chosen the user is presented with one of two sub-menus.  If there is currently no Administrative Password in effect the following menu appears:

Enter New Password_______

Confirm New Password_______

Press Enter or TAB to Accept

Press ESC to Abort

If there is already an Administrative Password in effect, the following menu appears.  To disable the password, use a carriage return as the new password.

Enter Current Password_______

Enter New Password_______

Confirm New Password_______

Press Enter or TAB to Accept

Press ESC to Abort

Unattended Start

Disabled -- default

Enabled

The Unattended Start  field controls the point at which the User Password is required.  If set to Disabled  the User Password is required before the system boots, either from disk or the network.  The user will be prompted for the password with the text string "Enter Password (1):"

If set to Enabled the system will go through automatic boot activity (for instance running CONFIG.SYS and AUTOEXEC.BAT when booting DOS from disk), however the keyboard will be locked and the User Password must be entered to unlock it.  The BIOS does not provide any prompt string so it is suggested that the last thing that the automatic login sequence does is prompt the user for the password.

The Unattended Start field can only be set if a User Password is in effect.

Security Hot Key (CTRL-ALT-)

Alpha-Numeric Key

The Security Hot Key (CTRL-ALT-) field can be used to define a key which when entered in conjunction with the CTRL and ALT keys puts the system into secure mode (locks the keyboard).  When this Hot Key combination is entered the Num Lock, Caps Lock, and Scroll Lock LEDs on the keyboard will flash on and off in sequence, indicating to the user that the system is in secure mode (as opposed to being hung).


    Exit Menu

Exit Saving Changes

The Exit Saving Changes field is used to exit the Setup Utility saving the current state of all parameters.

When the Enter key is entered the following sub-menu is displayed:

Exit Saving Changes?

Press Enter to Continue

Press ESC to Abort

If the Enter key is selected then the Setup Utility will be exited with all parameters set to their current values.  If the ESC key is selected, then the user is returned to the Exit menu without effecting any change.

Exit Discarding Changes

The Exit Discarding Changes field is used to exit the Setup Utility discarding any changes made to Setup parameters.  When the Enter key is entered the following sub-menu is displayed:

Exit Discarding Changes?

Technical Product Summary - Appendix C _ Phase II BIOS User's Guide - Introduction
Introduction

This User's Guide documents the "Phase II" BIOS Setup Utility.  It explains the overall organization of the utility, how to navigate through the utility, and individual fields and options.

This User's Guide was written based on Version 1.00.09.AF2.  This is the first implemenation of the "Phase II" BIOS on the Premiere/PCI Expandable Desktop (Batman's Revenge).  When newer versions of the BIOS are released, they may have additional features not documented in this User's Guide.

The "Phase II" BIOS Setup Utility is divided into 4 major menus:

Main Menu

Advanced Menu

Security Menu

Exit Menu

Each of the major menus occupy the left and center sections of the computer screen.  Selecting certain fields within the major menus will drop the user into sub-menus.  Displayed on the right side of the screen  is a Command Screen which describes the commands used to interact with the Setup Utility.  The following section documents these commands.  The subsequent four sections describe each of the main menus.  Sub-menus are documented within the main menus from which they are invoked   In each section the field which is being displayed is bold italic type.  If there are user selectable options for that field they are displayed in italic  type.  Explanations and comments about the fields and options are displayed in normal type.


Command Screen Navigation

To enter the Setup utility, press the <F1>  or the <DEL> key during the boot process.  The system will complete the POST tests and then enter the Setup utility.

The right side of the Setup screen contains a list of  commands which are available to the user as they navigate through and interact with the Setup Utility.  These commands are displayed at all times, for each menu and sub-menu.

F1	Help

Help is provided for a subset of the fields.  It can not be invoked when parameter options are being displayed.

ESC	Back

The ESC key provides a mechanism for backing out of any field.  When the ESC key is entered from the top level of any field, the field options cease to be displayed.  When the ESC key is entered from the top level of any sub-menu, the parent menu is re-entered.  When the ESC key is entered from the top level of any major menu the following screen is displayed:

Exit Discarding Changes

Press Enter to Continue

Press ESC to Abort

At this point pressing the Enter key will cause the user to leave the Setup Utility without saving any changes they might have made.  Pressing the ESC key will  bring them back to the top level of the current menu.

Enter	Select

The Enter key is used to activate sub-menus, change parameters and select parameter options.

Previous Item

The up arrow is used to move to the menu item above the current item.  It does not wrap around.

Next Item

The down arrow is used to move to the menu item below the current item.  It does not wrap around.

Select Menu

The left and right arrow keys are used to move between the 4 major menus. They do not wrap around.

F5	Setup Defaults

The Setup Defaults key is used to set all Setup Parameters to their default values.  When this key is pressed the following message appears:

Load Setup Defaults?

Press Enter to Continue

Press ESC to Abort

If the Enter key is selected then all Setup Parameters will be set to their default values.  If the ESC key is selected, then the user is returned to where they were before F5 was pressed without effecting any change.

F6	Previous Values

The Previous Values key is used to set all Setup Parameters to their previous values.  When this key is pressed the following message appears:

Discard Changes?

Press Enter to Continue

Press ESC to Abort

If the Enter key is selected then all Setup Parameters will be return to the values selected when Setup was entered.  If the ESC key is selected, then the user is returned to where they were before F6 was pressed without effecting any change.

F10	Save & Exit

The Save & Exit key is used to exit the Setup Utility saving the current state of all parameters   When this key is pressed the following message appears:

Exit Saving Changes?

Press Enter to Continue

Press ESC to Abort

If the Enter key is selected then the Setup Utility will be exited with all parameters set to their current values.  If the ESC key is selected, then the user is returned to where they were before F10 was pressed without effecting any change.


Main Menu Navigation

Each menu  contains a number of parameters.  Most parameters can be changed by the user, although some are informative only.  Parameters which can be changed by the user are displayed on the monitor in black, informative only parameters are displayed in blue.  Depending on the security option chosen and in effect (via password), a parameter can be either changeable or non-changeable.  A parameter which is non changeable due to insufficient security privilege or other reasons will be grayed out.  Parameters which have no effect based on the value of other parameters are not displayed.

Identification string returned from drive

Not Installed

The Hard Disk C: through Hard Disk F: fields report the presence of, and identification string reported by, up to 4 physical IDE drives (two each of PCI and ISA).  When the cursor is placed on one of these fields and it is selected by hitting the Enter Key, the Hard Disk Sub-Menu appears (see below) allowing parameters which affect the drives to be set.

Note:	Disk drive assignments

Drive letters will be assigned to physical drives as follows:

PCI IDE Interface Only

Master	C:
Secondary	D:

ISA Interface Only

Master	C:
Secondary	D:

ISA & PCI IDE Interface Two Drives Used

PCI Master	C:
ISA Master	D:

ISA & PCI IDE Interface Three Drives Used

PCI Master	C:
PCI Secondary	D:
ISA Master	E:
PCI Master	C:
ISA Master	D:
ISA Secondary	E:

ISA & PCI IDE Interface Four Drives Used

PCI Master	C:
PCI Secondary	D:
ISA Master	E:
ISA Secondary	F:
When drives have multiple partitions on them, partitions beyond the primary partition will be assigned in ascending order, based on available drive letters and other installed drives.  Partitions are assigned to primary partitions first (across multiple drives), and then to secondary partitions.  This means that when there are multiple drives with multiple partitions, the logical drive numbering scheme may result in discontiguous logical partitions on the same physical drive.

For instance, if there is a "Drive 1" with two partitions which is a Master on the PCI IDE interface, a "Drive 2" with three partitions which is a Slave on the PCI interface, and a "Drive 3" with two partitions which is a master on the ISA interface the drive letters will be assigned as follows:

Drive 1

Primary Partition	C:
Secondary Partition	F:

Drive 2

Primary Partition	D:
Secondary Partition	G:
Tertiary Partition	H:

Drive 3

Primary Partition	E:
Secondary Partition	I:


Hard Disk Sub-Menu

Hard Disk Type

Auto Configured -- default

User Definable

Number of Cylinders

Number of Heads

Number of Sectors

If	Hard Disk Type = Auto Configured

Then parameters reported by drive

If	Hard Disk Type = User Definable

Then parameters entered by user

The Number of Cylinders, Number of Heads, and Number of Sectors  fields display what is reported by the drive if Hard Disk Type is set to Auto Configured.  If Hard Disk Type is set to User Definable then these fields are entered by the user. Hard Disk Type should be set to Auto Configured unless the drive was formatted on another system with parameters different than those reported by the drive.

Maximum Capacity

Value calculated from Cylinder, Head, and Sector info above

Initialization Timeout

Disabled

5 Seconds

10 Seconds -- default

31 Seconds

Initialization Timeout selects the number of seconds the BIOS will wait to determine if an IDE drive is present, after initiating a transaction with the drive.  If a drive is present and responds to the BIOS before the Initialization Timeout period, then the BIOS will proceed, i.e. there is no boot-time penalty for a large value when a drive is present.  If a drive is not present, then the BIOS will wait the Initialization Timeout period before proceeding.  If a drive is present, but does not respond to the BIOS within the Initialization Timeout range, then the BIOS will not see the drive and it will not be accessible.  This value should be set to Disabled for any IDE drives not installed.  This parameter works in conjunction with the Hard Disk Pre-Delay parameter contained in the Boot Options sub-menu of the Main menu.

IDE Translation Mode

Standard CHS -- default

Logical Block

Extended CHS

Auto Detected

The IDE Translation Mode parameter controls the way in which the BIOS interacts with the drive in terms of drive geometry.  Proper choice is dependent upon the drive's size, capabilities, and the operating system (OS) used.

Standard CHS is the translation mode that has been in use for years.  Its use limits IDE capacity to a maximum of 528 Megabytes regardless of the size of the drive used.

Logical Block mode overcomes the 528 MB maximum size limitation imposed by Standard CHS mode. It should be used only when the drive supports LBA (Logical Block Addressing), and the OS supports LBA, or uses the BIOS to access the disk.

Extended CHS mode also overcomes the 528 MB maximum size limitation imposed by Standard CHS mode.   It can be used with drives which are larger than 528 MB, but do not support LBA mode.

Auto Detected allows the BIOS to examine the drive and determine the optimal mode. The first choice is to utilize Logical Block  mode if it is supported by the drive. The second choice is to utilize Extended CHS   mode if the drive topology allows.  If neither of the above two methods are possible, then Standard CHS mode is used.   Important NOTE: When set to Auto Detected the BIOS will detect what the drive is capable of, not the translation mechanism which was used to format the drive.  If a drive is run in a mode other than the mode in which  it was partitioned and formatted, unpredictable results may occur, including data loss.

Different operating systems have different abilities regarding IDE Translation Modes:

UNIX operating systems (as currently implemented) do not support either LBA or ECHS and must utilize the Standard CHS method. UNIX can support drives larger than 528 MB, but does so in its own way.

OS/2 2.1 can support LBA, ECHS or Standard CHS methods . Note that LBA support may require a switch setting on an OS/2 driver in order to operate in that mode. (*)

OS/2 2.0 & Novell Netware can support either ECHS or Standard CHS methods, but not LBA.

DOS & Windows can support LBA, ECHS or Standard CHS methods. If the "Fast 32-bit IDE" option of Windows is utilized, make sure to use the  Standard CHS setting only, unless a version of WDCDRV.386 is being used which supports these advanced geometrys.  You will get better performance NOT using "Fast 32-bit IDE" if using a drive which employs Mode 3 PIO on the PCI interface, unless using a version of WDCDRV.386 which supports these advanced modes.

Multiple Sector Setting

Disabled

4 Sectors/Block

8 Sectors/Block

Auto Detected -- default

The Multiple Sector Setting  field controls the number of sectors which are transferred by an IDE drive per interrupt generated.  If set to Disabled, then an interrupt will be generated for each sector transferred, even if the OS issues a multi-sector transfer.  If set to 4 Sectors/Block or 8 Sectors/Block then 4 or 8 sectors will be transferred per interrupt (for a request that is as large as, or larger than 4 or 8 sectors).  If Auto Detected is chosen, then x sectors will be transferred per interrupt, where x is the maximum value supported by the drive.  If a drive does not support multiple sectors/block then the BIOS will ignore this setting.  If the drive does not support the specific number (4 or 8) of sectors chosen, then the BIOS will default to the largest number of sectors the drive supports that are smaller than the chosen value.

Fast Programmed I/O Modes

Disabled

Auto Detected -- default

The Fast Programmed I/O Modes field controls the speed in which Programmed I/O (PIO) transfers occur on the PCI IDE interface.  If set to Disabled, transfers occur at an un-optimized (Mode 0) speed.  If set to Auto Detected, transfers occur at the rate which the drive reports as its maximum (up to and including the maximum mode 3 timing).  This field should only be set to Disabled if a drive is being used which incorrectly reports an ability to function with advanced timings.


Language

English (US)

..

..

The Language: field controls the language of the text strings used in Setup and the BIOS.  Any installed language will appear as an option in its own language (for example, German will appear as Deutch).  Only installed languages will appear as options.  Language may be installed using the FMUP utility and the appropriate .LNG file.


Boot Options Sub-Menu

When the cursor is placed the Boot Options: field and it is selected by hitting the Enter Key, the Boot Options Sub-Menu appears allowing parameters which affect the boot process to be set.

Boot Sequence

C: First, Then A:

A: First, Then C: -- default

C: Only

A: Only

The field controls the order in which the BIOS attempts to boot from the hard and floppy drives.

System Cache

Disabled

Enabled -- default

The System Cache field controls both the primary and secondary caches. Setting System Cache Disabled to will hurt performance, but might be required when running software which utilizes software timing loops and needs to be slowed down to execute properly.

Boot Speed

Turbo -- default

De-turbo

The Boot Speed field controls the system CPU cycles.  De-turbo mode slows the CPU by disabling system cache and adding increased refresh cycles.  It does not reduce CPU speed to 4.77Mhz or 8Mhz AT class machines.

Num Lock

Off -- default

On

The Num Lock field controls whether the keyboard Num Lock function is turned on or off when the system is booted.

Setup Prompt

Disabled

Enabled -- default

The Setup Prompt field controls whether the "Press <F1> Key To Enter Setup" message is displayed during POST (Power On Self Test).It does not control access, just the message.

Hard Disk Pre-Delay

Disabled

1 Second

2 Seconds

3 Seconds -- default

4 Seconds

5 Seconds

6 Seconds

7 Seconds

The Hard Disk Pre-Delay provides a mechanism which delays the BIOS's attempt to initialize the first  IDE drive in the system.  It is necessary because certain drives take longer than others to "spin up" and might hang if they are accessed too soon after being powered up or reset.  The delay is only honored for the first drive accessed. This parameter works in conjunction with the Initialization Timeout parameter contained in the Hard Disk Sub-menu of the Main menu.  The two are added together.

It should be noted that this new addition to the BIOS Setup is the result of our speeding up the POST process.

Typematic Rate Programming

Default -- default

Override

The parameter controls whether default or user configurable values are used for Typematic Rate Delay and Typematic Rate (see below).  If Default is chosen then Typematic Rate Delay is set to 500 msec and Typematic Rate is set to 15.  If Override is chosen the following two parameters appear, allowing the user to customize these values.

Typematic Rate Delay

250 msec -- default

500 msec

750 msec

1000 msec

The Typematic Rate Delay field controls how long it takes for the keyboard auto-repeat function to start when a keyboard key is held down.

Typematic Rate

6 char/sec -- default

8 char/sec

10 char/sec

12 char/sec

15 char/sec

20 char/sec

Peripheral Configuration Sub-Menu

Configuration Mode

 	Auto -- default

Manual

The Configuration Mode fields controls whether on board resources are manually or automatically set up.  When set to Auto, on board  system peripherals (IDE drives, Floppy Drive, Serial Ports, Parallel Port) are automatically configured during power up.  When set to Manual, system peripherals must be explicitly configured.  The following 6 fields (PCI IDE Interface to Parallel Port Address) are only user accessible when Configuration Mode is set to Manual.

PCI IDE Interface

 	Enabled -- default

Disabled

Standard ISA IDE Interface

Enabled -- default

Disabled

Floppy Interface

Enabled -- default

Disabled

The PCI IDE Interface, Standard IDE Interface, and Floppy Interface  fields allow these drive interfaces to be individually enabled or disabled.

Serial Port 1 Address

Disabled

COM1, 3F8h -- default

COM2, 2F8h

COM3, 3E8h

COM4, 2E8h

Serial Port 2 Address

Disabled

COM1, 3F8h

COM2, 2F8h -- default

COM3, 3E8h

COM4, 2E8h

The Serial Port 1 Address, Serial Port 2 Address fields allow the user to select the I/O ports used by these interfaces.  If a COM port is chosen for one of the Serial Port Addresses, it will not appear in the option list for the other Serial Port Address, i.e. if one of the Serial Port Addresses is set to Disabled, then there will be four choices for the other serial port address.  Otherwise there will be three choices.

Parallel Port Address

Disabled

LPT3, 3BCh

LPT1, 378h -- default

LPT2, 278h

The Parallel Port Address fields allow the user to select the I/O ports used by these interfaces.

Parallel Port Mode

Compatible -- default

Extended

When set to Compatible, the parallel port will be set up in a mode compatible with the original AT.  When set to Extended the parallel port will be set up in the most advanced mode allowed by the chipset (ex. ECC, ECP).

Serial Port 1 IRQ

Interrupt Used

Serial Port 2 IRQ

Interrupt Used

Parallel Port IRQ

Interrupt Used

The Serial Port 1 IRQ, , Serial Port 2 IRQ and Parallel Port IRQ  fields display the interrupts used by the Serial and Parallel Ports.  These values may not be changed by the user.  If an interface is disabled via the Serial Port 1 Address, Serial Port 2 Address, or Parallel Port Address fields, then the associated interrupt is not displayed, and is available for use by add in cards.


Advanced Chipset Configuration Sub-Menu

Base Memory Size

512KB

640 KB -- default

The Base Memory Size field controls the mapping of addresses between 512K and 640K (80000h-9FFFFh).  If 512KB is chosen then accesses between 512K and 640K are directed to the ISA bus.  When 640 KB is selected accesses between 512K and 640K are directed to system DRAM.  Unless using an ISA card which requires access to this particular address range this field should be set to 640 KB.

ISA Bus Speed

Compatible -- default

Enhanced

The ISA Bus Speed field controls the speed of the ISA Bus clock.  If set to Compatible the speed will fall within the limits defined by the IBM AT Technical Reference (6-8.33 Mhz).  If set to Enhanced the speed will be greater than the maximum defined by the IBM AT Technical Reference manual.  Modern ISA cards can operate with the enhanced speeds,  however some older cards can experience difficulties.  ISA performance will be enhanced when ISA Bus Speed is set to enhanced.   The actual value of the Bus Clock when set to Compatible or Enhanced is dependent upon the external frequency of the CPU:

External Frequency	Compatible	Enhanced
60 Mhz	7.5 Mhz	10 Mhz
66 Mhz	8.25 Mhz	11 Mhz
Byte Merging

Enabled

Disabled -- default

Byte Merging is a feature which increases performance for older applications which write to video memory in bytes instead of words.  However, this feature is not supported on all PCI video cards.  For best performance this field should be enabled unless a PCI graphics card which does not support this feature is used.  If this field is enabled and used with a card which lacks support video corruption will be seen in some video modes.

PCI IDE Prefetch Buffers

Enabled -- default

Disabled

This field is used to disable a set of prefetch buffers in the PCI IDE controller.  Disabling the buffers may be required when using Operating Systems (such as NT and OS/2) which do not use the BIOS to access the hard and do not disable interrupts when completing a programmed I/O operation.  Setting PCI IDE Prefetch Buffers to Disabled has negative performance implications.  Some operating systems may provide a patch to correct this problem, contact the operating system vendor for details.  A second work around is to disable the PCI IDE interface and use the ISA IDE interface only.

ISA LFB Size

Disabled -- default

1 MB

3 MB

7 MB

The ISA Video Linear Frame Buffer Size provides a mechanism for creating a hole in the system memory map.  Accesses made to addresses within this hole will be directed to the ISA bus instead of main memory.  This should be set to Disabled  unless you are using an ISA video card with a linear frame buffer or other ISA cards which require greater than 64K of memory and you are not using the Plug and Play run-time utilities (Configuration Manager & ISA Configuration Utility).

ISA LFB Base Address

Dependent upon ISA LFB Size

If	ISA LFB Size	Then	ISA  LFB Base Address
	Disabled		N.A.
	1 MB`		15 MB
	3 MB		13 MB
	7 MB		9   MB
The ISA Video LFB Base Address field displays the starting address of the ISA memory hole if a value other than Disabled is chosen for the ISA Video LFB Size parameter.  If  ISA Video LFB Size is set to disabled, then this field does not appear.  This field is informative only, i.e. it cannot be changed by the user.

Video Palette Snoop

Disabled -- default

Enabled

The Video Palette Snoop field controls the ability of a PCI graphics cards to "snoop" write cycles to an ISA video card's color palette registers.  This should normally be set to Disabled.  It should only be set to Enabled if:

An ISA card connects to a PCI graphics card via the VESA connector

AND that ISA card connects to a color monitor.

Note: This field will not show up if using the B stepping of a Cirrus 5434 graphics controller.

Latency Timer (PCI Clocks)

Number between 0 and 256

66 -- default

The Latency Timer (PCI Clocks) field controls the length of time an agent on the PCI bus can hold the bus when another agent has requested the bus.  Its default value is 66.  In general this should not be changed.  If there are latency sensitive cards in the system (such as audio cards and/or network cards with small buffers) this can be set to a lower value to reduce latency.  If there are no latency sensitive cards in the system, but I/O intensive applications are being run, this can be increased to slightly improve performance.


Plug and Play Configuration Sub-Menu

Configuration Mode

Use Setup Utility -- default

Use ICU

The Configuration Mode field is used to choose the method in which information about legacy ISA cards (ISA cards which do not have Plug and Play capabilities) is conveyed to the BIOS to allow the BIOS to set up PCI cards and ISA Plug and Play cards without conflicting with the legacy ISA cards.

If Use ICU is chosen, then the BIOS will depend upon information provided by run-time Plug and Play software (Configuration Manager and ISA Configuration Utility) to ensure that there are no conflicts with legacy ISA cards.  Only choose this method if your system is configured with these utilities and they are used. When Use ICU is chosen no other fields are displayed in this Sub-Menu.

If Use Setup Utility is chosen, then the BIOS will depend upon information provided by the user in the fields below to prevent conflicts between Plug and Play cards and legacy ISA cards.  If the Use Setup Utility is chosen, the user should not install and use run-time Plug and Play software (Configuration Manager and ICU).

ISA Shared Memory Size

Disabled -- default

16 KB

32 KB

48 KB

64 KB

The ISA Shared Memory Size field is used to define a block of system memory which will not be shadowed (shadowing is a technique which copies a block of memory from an add in card's ROM to the same address in  system memory to allow faster access to the code and achieve higher performance).  By default all upper memory is shadowed unless a block is un-shadowed using this and the ISA Shared Memory Base Address fields.

This field should be set to Disabled unless an ISA card is used which communicates with the CPU through a block of shared memory located in the upper memory area.  If set to a value other than Disabled  the ISA Shared Memory Base Address field will appear below.  Note that if a value of  64 KB is chosen, then the ISA Shared Memory Base Address field can only be set to D0000h or below.

ISA Shared Memory Base Address

C0000h

C4000h

C8000h

CC000h

D0000h

D4000h

D8000h

DC000h

The ISA Shared Memory Base Address field works in conjunction with the ISA Shared Memory Size.  See above.  This parameter is only displayed if the ISA Shared Memory Size parameter is not disabled.

IRQ 3*

IRQ 4*

IRQ 5

IRQ 7*

IRQ 9

IRQ 10

IRQ 11

IRQ 15*

Available

Used By ISA Card

* These options will not be visible if consumed by on-board resources (IRQ3 Serial Port 2, IRQ4 Serial Port 1, IRQ7 Parallel Port, IRQ 15, both IDE interfaces used).

The IRQ 3 - IRQ 15 fields are used to indicate whether individual interrupts are used by ISA legacy cards.  If not used, then they should be set to Available.  If used they should be set to Used By ISA Card.

Notes: All but one interrupt can be set to Used By ISA Card.  One must remain available for PCI cards which use interrupts to function.

On older systems that have the B stepping of the SIO PCI bridge component, only interrupts 9, 10 and 11 will show on this screen, even if additional interrupts are available.


Security Menu

There are two types of passwords available, User Password and Administrative Password.  The User password can be used to control access to the Setup Utility, the keyboard upon initial boot, and the keyboard when used in conjunction with the Security Hot Key.  The Administrative Password is used to control access to the Setup Utility.  The following table describes the interaction between these passwords:

Password In Effect	Enter Setup with User Password	Enter Setup with Administrate Password	Boot
User Password Only	Can change all fields	N.A.	User Password Required
Administrative Password Only	N..A.	Can change all fields	No  Password Required
Both	Can change limited number of fields	Can change all fields	User or Administrative Password Required
If the Administrative Password is in effect and Setup is entered with the User Password only the following fields may be changed:

System Date

System Time

User Password

Security Hot Key

User Password is

Disabled -- default

Enabled

Administrative Password is

Disabled -- default

Enabled

The User Password is and Administrative Password is fields indicate whether the User and Administrative passwords have been set.  If neither the User Password is or the Administrative Password is fields are set to Enabled neither the Unattended Start or Security Hot Key (CTRL-ALT-) fields will be displayed.

Set User Password

When the Set User Password field is chosen the user is presented with one of two sub-menus.  If there is currently no User Password in effect the following menu appears:

Enter New Password_______

Confirm New Password_______

Press Enter or TAB to Accept

Press ESC to Abort

If there is already a User Password in effect, the following menu appears.  To disable the password, use a carriage return as the new password.

Unattended Start

Disabled -- default

Enabled

The Unattended Start  field controls the point at which the User Password is required.  If set to Disabled  the User Password is required before the system boots, either from disk or the network.  The user will be prompted for the password with the text string "Enter Password (1):"

If set to Enabled the system will go through automatic boot activity (for instance running CONFIG.SYS and AUTOEXEC.BAT when booting DOS from disk), however the keyboard will be locked and the User Password must be entered to unlock it.  The BIOS does not provide any prompt string so it is suggested that the last thing that the automatic login sequence does is prompt the user for the password.

The Unattended Start field can only be set if a User Password is in effect.

Security Hot Key (CTRL-ALT-)

Alpha-Numeric Key

The Security Hot Key (CTRL-ALT-) field can be used to define a key which when entered in conjunction with the CTRL and ALT keys puts the system into secure mode (locks the keyboard).  When this Hot Key combination is entered the Num Lock, Caps Lock, and Scroll Lock LEDs on the keyboard will flash on and off in sequence, indicating to the user that the system is in secure mode (as opposed to being hung).


Exit Menu

Exit Saving Changes

The Exit Saving Changes field is used to exit the Setup Utility saving the current state of all parameters.

When the Enter key is entered the following sub-menu is displayed:

Exit Saving Changes?

Press Enter to Continue

Press ESC to Abort

If the Enter key is selected then the Setup Utility will be exited with all parameters set to their current values.  If the ESC key is selected, then the user is returned to the Exit menu without effecting any change.

Exit Discarding Changes

The Exit Discarding Changes field is used to exit the Setup Utility discarding any changes made to Setup parameters.  When the Enter key is entered the following sub-menu is displayed:

Exit Discarding Changes?

Typematic Rate Programming	Enabled or Disabled. Default is disabled. When enabled, the following two typematic options are valid.
Typematic Rate Delay (msec.)	250, 500, 750 or 1000 millisecond delay. Default is 500. Determines how long it takes for the auto-repeat function to start when a person is holding down a key on the keyboard.
Typematic Rate (Chars/sec)	6, 30, 24, 20, 15, 12, 10 or 8 characters/second. Default is 15. Determines the speed at which characters repeat when you hold down a key on the keyboard. The higher the number, the faster the repeat.
Press <F1> Message Display	Enabled or Disabled. Default is enabled. The message "Hit <F1> to Enter Setup" appears on the screen during the power up sequence.
System Boot Up Num Lock	On or Off. Default is off, reflecting the state of the "Num Lock" keyboard feature when the system boots.
System Boot Up Sequence	Drive A: before C:, Drive C: before A:, or Drive C: Only. Default is to check Drive A: before C: for an operating system, which allows the user to boot from a floppy if necessary.
System Boot Up CPU Speed	High or Low. Default is High. If high is selected, boot up will occur at full speed. If low is selected, the board is put into de-turbo mode, which results in slower operation.
Cache Memory	Enabled or Disabled. Default is enabled. Both the L1 and L2 cache are enabled or disabled by this selection.
Network Password Checking	Enabled or Disabled. Default is disabled. If enabled, the system will complete the entire boot-up process, but the keyboard will remain locked until the password sequence is typed.
ISA Linear Frame Buffer	Disabled, 1 MB, 2 MB, or 4 MB. Default is disabled. The linear frame buffer is primarily for ISA video cards. If enabled, improvement may be noted in performance of ISA video cards using the linear frame buffer. It also provides a means to access memory located on the ISA bus immediately below 16MB.


Advanced CMOS setup (Continued)

Set Linear Frame Address to	When you enable the ISA linear frame buffer, this entry is displayed automatically. When you disable the linear frame buffer, this entry becomes N/A.
Disable Shadow Memory Size	Enabled or Disabled. Default is disabled. This selection is tied to the next selection "Disable Shadow Memory Base". If the shadow memory base is set to either C0000H or D0000H, then you can select a shadow memory size of either 16, 32, 48, or 64 KBytes.
Disable Shadow Memory Base	This selection allows the user to alter where the non-shadowed memory is located. The choices are either in the C0000H or D0000H range. There are several options within each range. For example, within the C0000H range you can choose C0000H, C4000H, C8000H, or CC000H. This setting effects the previous menu selection. Once you have made your selection in this menu your choices in the previous menu "Disable Shadow Memory Size" may be altered. The maximum size of the shadow memory is 64KB. You can only achieve 64kB if you specify the Shadow Memory Base to be at C0000H or D0000H. As you select the other shadow memory base options, you will notice that the shadow memory size begins to get smaller.
Base Memory Size	640/512. Default is 640KB. Provides a means to disable on-bd DRAM to access memory locations from 80000-9FFFFH on the ISA bus.
IDE DMA Transfer Mode	Default is disabled. When enabled, the user can choose from 3 different types of IDE DMA transfers: Standard (compatible), Type B, or Type F. Type F is the fastest DMA transfer mode.
IDE Multiple Sector Mode	Default is disabled and this selection is tied to the previous selection (IDE DMA Transfer Mode). When enabled, choices are 1, 2, 4, 8, 16, 32, or 64 sectors per burst (S/B). This setting programs the IDE DMA cycles to transfer multiple sectors per burst. A setting of 64 S/B assures the maximum burst size supported by the drive that is installed in the system.
IDE LBA Translations	Enabled or Disabled. Default is disabled. When enabled, supports Logical Block Addressing to allow full utilization of drives larger than 528 MB.
Enhanced ISA Timing	Enabled or Disabled. Default is disabled. When enabled, the ISA bus will run at 10 MHz. This results in faster system performance if the ISA agents in the system can tolerate 10 MHz (instead of the standard 8 MHz).
ISA IRQ 9	Free or Used. If an ISA agent in the system uses this interrupt, it must be specified here as used. The PCI auto-configuration code checks this entry and may attempt to use the interrupt is it is free.
ISA IRQ 10	Free or Used. If an ISA agent in the system uses this interrupt, it must be specified here as used. The PCI auto-configuration code checks this entry and may attempt to use the interrupt is it is free.
ISA IRQ 11	Free or Used. If an ISA agent in the system uses this interrupt, it must be specified here as used. The PCI auto-configuration code checks this entry and may attempt to use the interrupt is it is free.

If the utility is obtained from the bulletin board, UNZIP the archive and copy the files to a bootable MS-DOS 3.3, 4.01, 5.0, or 6.0 diskette. Reboot the system with the upgrade diskette in the bootable floppy drive and follow the directions in the easy to use menu-driven program.


Recovery mode

In the unlikely event that a FLASH upgrade is interrupted catastrophically, it is possible the BIOS may be left in an unusable state. Recovering from this condition requires the following steps (be sure a power supply and speaker have been attached to the board, and a floppy drive is connected as drive A:):

1.	Change Flash Recovery jumper (RCVR FLASH) to the recovery mode position.

2.	Install the bootable upgrade diskette into drive A:

3.	Reboot the system.

4.	Because of the small amount of code available in the non-erasable boot block area, no video is available to direct the procedure. The procedure can be monitored by listening to the speaker and looking at the floppy drive LED. When the system beeps and the floppy drive LED is lit, the system is copying the recovery code into the FLASH device. As soon as the drive LED goes off, the recovery is complete.

5.	Turn the system off.

6.	Change the "FLASH RECOVERY" jumper back to the default position.

7.	Leave the upgrade floppy in drive A: and turn the system on.

8.	Continue with the original upgrade.
