Pre-Production, Fab 2

All boards with a -200 PBA number, or PB number of 632142-001 are early pre-production fabs and are not supported.


Pre-Production, Fab 3

Boards prior to a -304 PBA number are early pre-release products and are not supported.  A non-comprehensive list of changes follows:

-300    Initial release of Fab 3.

-301    Changed to B-stepping of clock generator, changed TSC to 66mhz version.

-302    Changed value of IOR/IOW resistors on IDE interface from 100 to 47 ohms, added 10pf caps to HCLK and PCLK lines, removed resistors R2K1 and R2K3, cut in BIOS 1.00.01.BT0.

-303    Change resistors R2E7 from 22 to 47 ohms and R2E10 from 22 to 68 ohm for EMI reduction, changed clock generator, added 15pf caps @ C2D3 and C2E1, added wire for EMI fix.


Production Release, April '95

Initial production release.  Change Triton chipset to process 650 components, change video DRAM from 70ns to 60ns parts.  Add 10K resistors from R6F11 to R6F6 and from J9F2 pin 29 to J9E1 pin 2.  Change C5H1, C9D1, and C9D6 to .1uF caps.

BEXXLP0NCNA	633570-304


New BIOS, May '95

Class II type change.

Cut in new BIOS that reduces the video memory clock from 60 to 57 MHz.  Also cuts in several bug fixes, see the BIOS History section for details.  The video DRAM part numbers also changed to insure that parts would meet the timing specifications.

These changes were made in response to a re-evaluation of the timing requirements of the video memory circuitry.  It was determined that standard video DRAM memory would not meet the timing specification required by a 60mhz video memory clock.  In addition, at 57mhz, only 60ns memory components and specially screened 70ns memory components would meet the timing requirements.  No field failures were reported, failure symptoms would include sparkles on the display in high resolution modes.

Triton Chipset Stepping Change, June '95

Class II type change

The Triton chipset is moving to a new stepping of the TSC (location U3D1) and PIIX (location U4F1).  In conjunction with this change, two rework resistors will also be removed.  A shorting bar is also being added between the parallel port and video port connectors to improve the grounding characteristics.

The TSC is moving from A-1P to A-2.  The new step of the TSC incorporates a metal layer change in the P-UNIT (PCI Interface).  An OR gate was inserted in the PCI interface state machine.

The PIIX is moving from A-1P to A-1.  The new step of the PIIX is a metal layer change to ground a gate input to keep internal pull up resistors on #DACK0 and TC always active.  This allows the rework resistor located between R6F11 and RF6 and the rework resistor located between J9F2 and J9E1 to be removed.

National 87306 Stepping Change, August '95

Class II type change, ECO 2223

The National 87306 Ultra I/O controller is moving from the A-step to the B-step. This stepping includes the ability to switch DMA addresses on the Enhanced Capability Parallel (ECP) Port. This functionality is being incorporated to fully meet Windows* 95 specifications. Boards with the A-stepping of this part will pass Windows 95 compatibility testing with a contingency that the new stepping be cut in at a later date. The new component stepping is backward compatible with the existing BIOS, although a new BIOS will be required to take advantage of the new features. The B-step part also corrects several minor errata issues that exist in the A-step part. Details of all the component changes are listed below:

1) When working with Standard parallel Port (SPP) with: EPP 1.9 enabled and, /ZWS option disabled, wrong data might be forced on PD0-7 during an SPP write cycle. This is fixed in the PC87306VUL RevB.

2) The PC87306VUL RevA supports one DMA channel for ECP. Pins 138 and 70 are reserved as well as bits 1, 2, and 3 of SCF1. The PC'95 Hardware Design Guide requires at least 2 DMA options for ECP. The PC87306VUL RevB provides a second DMA channel for ECP. Pin 138 is now assigned to signal /PDAKC1, and pin 70 has been assigned to signal PDRQ. Bit 3 of the SCF1 selects between the two DMA channels.

3) IRQ3 and 4 are allocated according to COM selection. They cannot be assigned independently of the address selection. This is the "legacy" mode standardized by industry and in all NSC SIOs. The PC'95 Hardware Design Guide, however, redefines the UART mode of operation so each UART has 2 IRQ options regardless of the selected address. The PC87306VUL RevB device supports both the "legacy" mode of operation and also independent IRQ3 and 4 options for each UART via bits 2 and 6 of PNP1.

4) IRQ5 and 7 are allocated according to LPT selection. They can not be assigned independent of the address selection ("legacy" mode). The PC'95 Hardware Design Guide, however, defines the Parallel Port as having two IRQ options independent of the selected address. The PC87306VUL RevB supports both the "legacy" mode of operation as well as providing independent IRQ5 and 7 options for the Parallel Port via bits 4 and 5 of PNP0.

5) The PC87306VUL RevA does not support the two lockable bits on SCF1 bits 6 and 7 and the lck bit 3 of FCR. The PC87306VUL RevB supports this feature.

6) The PC87306VUL RevA provides chip select for 10-bit and 16-bit address decode. Bit 3 of CS1CF is reserved. The PC87306VUL RevB provides another option to support the upper-14 bit address decode via bit 3 of CS1CF.

7) The EPP mode supports 2 base addresses, 278h and 378h. The PC'95 Hardware Design Guide requires at least three addresses. The PC87306VUL RevB provides a programmable third option via bit 6 of PNP0 and the LPTBA register.

New Baseboard Fab, August '95

Class II type change, ECO E02264

A new revision of the baseboard will be cut in that improves the manufacturability of the product and improves signal quality. A detailed description of the changes follow:

•	Pulldown resistor, R6F5 10K 5% on signal TC, was changed to a pullup resistor for signal quality improvement.

•	Added a 10K 5% pullup resistor at location R8F16 on signal DDAK0 for signal quality improvement.

•	Added a 33pf capacitor at location C7B1 on the signal MOE for noise reduction.

•	Modifying the plane split and increasing ground connections to the "wagon wheel" mounting hole next to J1K1 for an improved EMI signature.

•	Removing solder resist on the torriod site for improved manufacturability.

•	Moved two traces at the edge of the CPU socket for clearance from the heatsink clip.

•	Changed the size of the plated thru-hole on pin 6 and pin 12 of the power connector from 75mil +/-5mil to 60mil +/-2mil

•	Removed resistor R2B1, R2B2, R2B3, and R2B6 from EWBE* and WB_WT* on the CPU socket (pins W3 and AA5). EWBE* is now hard-wired to GND and WB_WT* is hard-wired to VCC3.

•	Added components BF1 and BF2 to pins W33 and X34 of the CPU socket.

•	Added two resistor sites, one to VCC3 and the other to GND, on signal MISC1, pin U35 of the CPU. Reference designators are R4A1 and R4A2.

•	Added an extra 50mil ground trace on the secondary side between J3K1 and J1K1.

•	Added an alternate site for a 3.3V 1500uf cap.

•	Added an alignment hole for the 2-pin fan connector at J8A1.

•	Added a 5V tie pin to pin 13 of the TSOP package at U5H1.

•	Corrected a silk-screen error at C9F4/C9F7 (swapped).

•	Added a 2 line label target for custom label information. Located near the CPU socket.

•	Changed an empty label site in the middle of the PCB to an "AA#" site.

•	Added one 0805 capacitor site in the VR circuit for potential noise reduction. Unstuffed at this time.

•	Changed the reference designator on the battery socket from XB7A1 to B7A1.

•	Changed the reference designator on the speaker from SPK1C1 to LS1C1.

EPP multiple DMA Channel Support, August '95

Class II type change.

0 ohm resistors were added to sites R7H7 and R7H10 to provide support for an alternate DMA channel when the printer ports is set for EPP or ECP mode.  This is a requirement for Windows 95 logo certification.

Also, two resistors, R2B1 and R2B6, were removed from the parts list.  These resistors are not required on the new fab (-40X level boards).

Floppy Drive Change, December 95

Class III type change

Planned Implementation Date - This will be an incremental change depending on the availability of the product. Also, there will be no more notifications regarding this change.

Intel is in the process of implementing a change to the TEAC model FD-235HG-XXXX floppy drive used in our systems. This change will affect all systems that are fitted with a 3.5 inch floppy disk drive. The form, fit and function of the drive have not changed, although some differences may be noted upon close inspection. The top cover of the drive has changed from a Tin plate material to a galvanized sheet. There have also been minor mechanical changes made to the drive. The mechanism for removing disks from the drive has been improved to facilitate more reliable performance. The head carriage assembly has changed, but is functionally equivalent to the previous model. There will be no revision to part numbers for either the drives, or systems affected.

Beta 6.01

o	Fixed the recovery problem in which the BIOS fails to recover when the sytem is set to recovery mode.

Release 5.0

o	None.

Beta 5.03

o	Fixed the problem in which the BIOS fails to detect IDE drives on external ISA IDE controller.

o	Fixed the problem with mode 3/4 IDE drives.

o	Added the "Primary PCI IDE Interface" and "Secondary PCI IDE Interface" options in the Peripheral menu to support disabling or enabling the primary or secondary IDE channel.

o	Added support to free IRQ14 or IRQ15 when either the Primary or Secondary PCI IDE channel when either one is disabled via setup.

Beta 5.02

o	CPU Auto Halt fix (save 5 more Watt).

o	New ATA detection.

o	Token-Ring remote boot fix.

o	Gate A20 race condition fix.

o	Fixed the problem in which the date and time fields in Setup were not being able to be changed using the number keypads.

Beta 5.01

o	Added support for Plug-and-Play Crystal Audio.

Release 4.0

o	Changed device node id for the parallel port from 400h to 401h when programmed to operate in ECP mode.

Beta 4.01

o	S3 Trio 32 video bios version 1.03-08-12.

o	Updated code so function 40h(Get PnP ISA config structure) doesn't use NVRAM.

o	Turbo/Deturbo in SMM.  However operating systems that hook int 9 will prevent turbo/deturbo from working as expected.

o	Changed APM function 53, subfunction 0AH that indicates that the system does not have a battery (No System Battery).

o	Added a more robust APM harddisk activity check that helps prevent the system from powering down in the middle of a disk operation.

o	Adjusted the way PS/2 mouse state (installed/deinstalled) was stored to prevent incompatibility with SCO UNIX. Open desktop was unable to function when IRQ 12 set to latch mode as opposed to ISA mode.

o	Fixed Int 15h function DAh subfunction 12h CX=02h (read cache status) in CX upon return to indicate Valid Cache size of zero (no cache installed), previously returned invalid cache size.

o	Change to Int 15 Function DAh Subfunction 92h - DX now returns the CPU internal speed in BCD for all supported processors.

o	Support for single language only.

o	Added new "User CMOS Defaults" save capability via INT 15h interface.  Added CMOS Information Storage and Retrieval and Force CMOS Defaults/Clear ESCD functions.

o	Fixed CMOS default when selecting Setup/Advanced/PnP Configuration/Use ICU option from Win 95 to NULL.

o	Fixed EDO detection algorithm problem.  If no SIMMs installed in bank 0, then bank 0 was programmed in EDO mode and not Fast Page mode.  (DCS # 3262, 3634, 3635,3636, 3637)

o	Added support for INT 15h C7h function (Get Memory Map for ISA Holes) which is is used by IBM OS/2.  This function is fully supported as specified IBM Personal System/2 Personal Computer BIOS Interface (Part # S04G-3283-00).

o	Fixed APM problem of user suspend request not being posted when the hot key is depressed.

o	Adjusted APM code to not repost events in the sleep and suspend handlers. This reporting would sometimes cause the system to appear hung. This hang appeared due to APM not being able to process a request to suspend or standby because an interrupt was pending.

o	Fixed APM problem where code would loop going into and out of SMM when trying to come out of a powered down state, and video was disabled (not power managed) in setup.

o	Fixed device nodes to not checksum device node data so we would comply with and pass Microsoft BIOS Test.

o	Adjusted PS/2 mouse device node to be dynamic and not static to comply with WIN 95 requirements.

o	Adjusted CMOS allocations to use 33h for the TSC cache information storage. This frees up CMOS byte 36h for OEM usage.  Also cleaned up PIC definitions for the PC87306 so that they no longer use equates in the banner file.

o	Fixed an error that showed up in manufacturing with a test card and could potentially show in the field .  If in setup Setup/Advanced/PnP Configuration/Use ICU option is selected and Boot PnP OS is set to None, then potentially the error bit for no boot device found may be set .  User could see "No boot device found" message and still boot properly.

o	Fixed Bus Mastering IDE I/O port value communicated via the device node interface to a corrected value.

o	Fixed information returned from 32 bit interface call to "Get PCI Routing Information" to prevent failing the NSP test.

o	Fixed parallel port setup choices so that I/O address 3BCh does not appear when the mode ECP or EPP is chosen.  Conversely,  neither mode ECP nor EPP appear where 3BCh is chosen as I/O address of parallel port.

o	Removed IDE timeout and predelay due to improved algorithm for detection of ATA devices.

o	Adjusted product information parameters for manufacturing modes.

o	Fixed runtime interfaces so that we do not force a disable of NMI when acccessing CMOS.

o	Fixed memory allocations for PCI devices such that they are aligned on 400h block boundaries according to the ESCD specification.

o	Fixed the PCI bridge code such that if no memory is requested by a bridge or the devices behind it, 1 MB is automatically allocated to it.  Also fixed situation where PCI bridge or devices behind it would request greater than 1GB of memory such that 1 GB is maximum limit for the bridge.

o	Added interface to core BIOS to provide INT 17h for EPP BIOS on a as needed basis.

o	Fixed keyboard controller interface code so that keyboard detection failure does not occur for higher end processors (100 Mhz or greater).

o	Fixed setup field related to fourth boot device to point to appropriate CMOS entry.  Previously pointed to third device entry.

o	Added capability to perform custom keyboard initialization on a per product basis.

o	Fixed the shadowing of PnP device ROMs.  PnP devices are now checked and shadowed  or  not based on device configuration.  Previously, all PnP devices were shadowed whether they requested it or not.

o	Fixed parameter checking for device node "Get" and "Put" calls so that Win 95 "BIOS Test" completes properly.

o	Adjusted code so that "Get Node" calls will preserve all 32 bit registers.

o	Fixed the ATA code use of the Set Features command to distinguish between mode 3 and mode 4 drives.  Possible cause of periodic data corruption on mode 4 drives only. Adjusted PIIX IDE timings to add an extra clock for mode 4 drive running at 25 Mhz PCI bus speed.

o	Fixed the code to properly allow all invalid PCI bus reads and writes performed by the PCI diagnostic tests.  Previous PCI specification required all reads and writes to be checked for validity within the device configuration spaces.

o	Added PC87306B support.

Release 3.0

o	Included new video bios 1.03.08.12 that fixes the problem where palette snooping was always turned off.

o	Fixed security hotkey, the key entered by the user in setup was being reprogrammed in the keyboard controller.  The bios was writing the user entered value then later writing the scan code for the back space key.

Release 2.0

o 	Fixed problems with S3 Trio 32 Video failures via reduction in Video Bios Clock rate reduction from 60Mhz to 57Mhz.  Also corrected font issues.  Video bios revision 1.03.08.09-57Mhz.

o	Fixed problem with ISA Shared Memory Setup options which was introduced between Beta 2.01 and Beta 2.02.  Now back to Beta 2.01 and Release 1.0 operation.  Failure was characterized by a failure of PCI video (with video error beep) when one would set the ISA Shared Memory option to start at C8000h.

o	Fixed problem introduced since Release 1.0 which would cause Protected Mode applications/Operating Systems to have a General Protection Fault when modifying the Device Node  configurations for onboard Parallel Port or onboard PCI IDE.

o	Fixed problem revolving around Bios Data Area offset 6Ch (dword - 32 bit value) aka Timer Count value.  Symptom of problem fixed:  "incorrect updating of Timer Count value in Bios Data Area occurs during Sleep/Power-Down when running Windows 95".  Fixed by utilizing Real Time Clock AND IRQ 0 (was previously only IRQ 0) as conditions for updating Timer Count value in Bios Data Area.

o	Added enhancement to APM code to allow audio feedback (beeping) which indicates APM code detection of:

a)	Sleep/Resume/Soft Power Off button press (single beep),

b)	Soft Power Off via 2 second hold of Sleep/Resume/Soft Power Off button (two decending beeps).

Beta 2.02

o	Adjusted Language Set Support to handle Single Language Sets only (U.S. English only, French only, Spanish only, Italian only, or German only).  Previous Releases supported Dual Language Sets (U.S. English and one of the following languages:  French, Spanish, Italian, or German).  However, due to size issues only Single Language Sets can now be supported.

o	Fixed PCI code dealing with devices Disabled (DCS #2966).

o	Fixed OS/2 trap problem related to APM being Enabled/Disabled in SETUP.

o	Fixed issue related to stack handling during compatible Shutdown 9.

o	Adjusted Resource Auto-configuration order for Windows 95 so that Motherboard Resources will be allocated before PCI resources.  This has been implemented via a SETUP option.

o	Adjusted PCI Resource allocation related to Video IRQ assignment.  We can now, on a product by product basis, decide to not assign IRQ's to PCI Video devices.

o	Fixed the programming of the Cache Line Size and Latency Timer for Bridges.

o	Fixed Motherboard Device Node Attributes to indicate "device can only be configured at runtime" from "device can be configured at runtime".  This fixes issue with WINICU R1.41 which thought the motherboard devices could be reconfigured for a next boot situation but the System Bios doesn't support this.

o	Fixed SETUP code to make sure one interrupt was preserved for PCI usage.

o	Fixed IDE timing programming so that when have two different mode drives ona single channel the slower mode will get programmed for that channel.

o	Fixed SETUP code for display of IRQ 5 and IRQ 7 in Plug and Play screen.

o	Fixed PCI and ISA PnP auto-configuration code so that a Configuration Error is flagged and the device is not disabled (DSC #3394).

o	Adjusted ISA PnP auto-configuration code so that back-to-back Isolation is not performed.  This helps certain ISA PnP cards which cannot handle this.

o	Fixed IDE auto-configuration code so that an empty IDE channel (an IDE channel without any drives connected to it) woul not hang the System Bios at POST-Time.

o	Fixed jump to wrong label in ISA PnP auto-configuration code.

o	Fixed PCIDIAG V1.2 hang and extraneous PCI.EXE entries.

o	Removed IDE timeout and predelay due to improved algorithm for detection of ATA devices.

o	Fixed setup field related to fourth boot device to point to appropriate CMOS entry.  Previously pointed to third device entry.

o	Fixed the ATA code use of the Set Features command to distinguish between mode 3 and mode 4 drives.  Possible cause of periodic data corruption on mode 4 drives only. Adjusted PIIX IDE timings to add an extra clock for mode 4 drive running at 25 Mhz PCI bus speed.

Release 3.0

o	None.

Release 2.0

o	None.

Beta 2.02

o	Fixed IDE timing programming so that when have two different mode drives ona single channel the slower mode will get programmed for that channel.

o	Fixed issue where PIIX Bus Mastering IDE was not being enabled.

Beta 2.01

o	Fixed IDE auto-configuration code so that an empty IDE channel (an IDE channel without any drives connected to it) woul not hang the System Bios at POST-Time.

o	Fixed Int 13h, Function 0Ch which was returning invalid value in AH.

o	Adjusted ATA code to issue a second reset after ATA initialization to fix problem seen in some IDE CD-ROM drives not being accessible after boot.

o     Fixed issue of system hang when no onboard IDE hard disks are installed in the system.

Beta 1.01

o     IDE ATA Support added.

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 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.)


Plug and Play (Windows 95, etc.)

Release 6.0

o	None.

Beta 6.01

Beta 4.01

o	Updated code so function 40h(Get PnP ISA config structure) doesn't use NVRAM.

o	Added new "User CMOS Defaults" save capability via INT 15h interface.  Added CMOS Information Storage and Retrieval and Force CMOS Defaults/Clear ESCD functions.

o	Fixed CMOS default when selecting Setup/Advanced/PnP Configuration/Use ICU option from Win 95 to NULL.

o	Fixed device nodes to not checksum device node data so we would comply with and pass Microsoft BIOS Test.

o	Adjusted PS/2 mouse device node to be dynamic and not static to comply with WIN 95 requirements.

o	Fixed an error that showed up in manufacturing with a test card and could potentially show in the field .  If in setup Setup/Advanced/PnP Configuration/Use ICU option is selected and Boot PnP OS is set to None, then potentially the error bit for no boot device found may be set .  User could see "No boot device found" message and still boot properly.

o	Fixed Bus Mastering IDE I/O port value communicated via the device node interface to a corrected value.

o	Fixed information returned from 32 bit interface call to "Get PCI Routing Information" to prevent failing the NSP test.

o	Fixed runtime interfaces so that we do not force a disable of NMI when acccessing CMOS.

o	Fixed memory allocations for PCI devices such that they are aligned on 400h block boundaries according to the ESCD specification.

o	Fixed the PCI bridge code such that if no memory is requested by a bridge or the devices behind it, 1 MB is automatically allocated to it.  Also fixed situation where PCI bridge or devices behind it would request greater than 1GB of memory such that 1 GB is maximum limit for the bridge.

o	Fixed the shadowing of PnP device ROMs.  PnP devices are now checked and shadowed  or  not based on device configuration.  Previously, all PnP devices were shadowed whether they requested it or not.

o	Fixed parameter checking for device node "Get" and "Put" calls so that Win 95 "BIOS Test" completes properly.

o	Adjusted code so that "Get Node" calls will preserve all 32 bit registers.

o	Fixed the code to properly allow all invalid PCI bus reads and writes performed by the PCI diagnostic tests.  Previous PCI specification required all reads and writes to be checked for validity within the device configuration spaces.

Release 3.0

o	None.

Release 2.0

o	Fixed problem with ISA Shared Memory Setup options which was introduced between Beta 2.01 and Beta 2.02.  Now back to Beta 2.01 and Release 1.0 operation.  Failure was characterized by a failure of PCI video (with video error beep) when one would set the ISA Shared Memory option to start at C8000h.

o	Fixed problem introduced since Release 1.0 which would cause Protected Mode applications/Operating Systems to have a General Protection Fault when modifying the Device Node  configurations for onboard Parallel Port or onboard PCI IDE.

o	Fixed problem revolving around Bios Data Area offset 6Ch (dword - 32 bit value) aka Timer Count value.  Symptom of problem fixed:  "incorrect updating of Timer Count value in Bios Data Area occurs during Sleep/Power-Down when running Windows 95".  Fixed by utilizing Real Time Clock AND IRQ 0 (was previously only IRQ 0) as conditions for updating Timer Count value in Bios Data Area.

Beta 2.02

o	Fixed PCI code dealing with devices Disabled (DCS #2966).

o	Adjusted Motherboard Device Nodes to ignore the Checksum (per the "Plug and Play BIOS Specification" Version 1.0A) for Set System Node.

o	Fixed Bios Error Display code to Not Display Resource Conflict Message when no PS/2 Mouse and add-in card using IRQ 12.

o	Adjusted Resource Auto-configuration order for Windows 95 so that Motherboard Resources will be allocated before PCI resources.  This has been implemented via a SETUP option.

o	Adjusted PCI Resource allocation related to Video IRQ assignment.  We can now, on a product by product basis, decide to not assign IRQ's to PCI Video devices.

o	Fixed the programming of the Cache Line Size and Latency Timer for Bridges.

o	Fixed Motherboard Device Node Attributes to indicate "device can only be configured at runtime" from "device can be configured at runtime".  This fixes issue with WINICU R1.41 which thought the motherboard devices could be reconfigured for a next boot situation but the System Bios doesn't support this.

o	Fixed SETUP code to make sure one interrupt was preserved for PCI usage.

Beta 2.01

o	Fixed 32 bit PCI Set Irq to check for valid PCI Busses.  PCI Local Bus Specification Revision 2.1 change.

o	Fixed PCI and ISA PnP auto-configuration code so that a Configuration Error is flagged and the device is not disabled (DSC #3394).

o	Adjusted ISA PnP auto-configuration code so that back-to-back Isolation is not performed.  This helps certain ISA PnP cards which cannot handle this.

o	Fixed jump to wrong label in ISA PnP auto-configuration code.

o	Fixed PCIDIAG V1.2 hang and extraneous PCI.EXE entries.

Release 1.0

o     None.

o	Fixed problem revolving around Bios Data Area offset 6Ch (dword - 32 bit value) aka Timer Count value.  Symptom of problem fixed:  "incorrect updating of Timer Count value in Bios Data Area occurs during Sleep/Power-Down when running Windows 95".  Fixed by utilizing Real Time Clock AND IRQ 0 (was previously only IRQ 0) as conditions for updating Timer Count value in Bios Data Area.

Known Errata With This Release

o	None


Features Still To Be Added / Comments About This Release

o	ATAPI Support has been removed.

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 excpect 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

Latest ECO Notification

Dear Advanced/MN Customer,	January 22, 1996

Our policy is to notify customers of planned changes and enhancements to Intel products as far in advance as possible (usually up to 60 days). This is a list of changes forecasted for the Intel Advanced/MN Low Profile boards and systems. Many of these changes are in process; dates are approximate and subject to change.

Forecasted changes for product codes

BP75LP0NCNA, BP90LP0NCNA, BEXXLP0NCNA

S75LPM8NC, S90LPM8NC, S75LPM8FNC, S90LPM8FLC, S100LPM8FLC, S120LPM8FLC

BIOS Update  Class I

Planned implementation date: January 96

A new version of the BIOS - release 5 was expected to be cut in this month but there was a broken recovery code found in it at the last minute. Due to this reason release 5 has been pulled back and now release 6 is expected to be released in January 96.  Please see the BIOS history section for the details on the changes included.

Added CE mark to the labels (ECO# 5526786A)  Class III

Implementation date: The change has been implemented

Marked "CE" on  the shipping carton label per European Union Council Directive 93/68/EEC.  The "CE" will also help product move through customs.

Battery Circuitry Change: Class III

Planned Implementation Date: February 96

The vbat change consists of replacing a diode with a zero ohm resistor (this eliminates the .6 V drop to vbat input of National Ultra I/O) and replacing the 1K battery resistor with a 1.2 to meet UL. The schedule has been changed to February 96.

System Changes

New Product Code - Class I

Effective date: February 96

A new system product code - S133LPM16ELC has been introduced to the channels.  The system features T32, 16M EDO, 256 15ns asynch cache, 133MHz processor.

EDO SIMM Addition - Class I

Planned Implementation Date: February 96

EDO SIMMs will be added to the bill of material as the preferred part for the system level products, Fast Page SIMMs will be changed to alternate status.  These products have been thoroughly qualified and tested with EDO SIMMs.  Fast Page SIMMs were initially called out in these products because of availability issues with EDO.  Availability of EDO SIMMs is no longer an issue.

Systems with EDO SIMMs installed may have better performance compared to systems with Fast Page mode SIMMs installed.  Other than this slight performance difference, there should be no other differences.  Fast Page mode SIMMs can still be installed in the empty SIMM sockets, the BIOS will automatically detect which type of SIMM is installed and configure the board accordingly.  One limitation should be noted: Fast Page and EDO should not be mixed within the same memory bank.  See the Technical Product Summary or User's Guide for more details.

Please contact your Intel field sales representative if you have any questions concerning these changes.

Intel CPU Errata

5.  SMI# and FLUSH# during Shutdown

WORKAROUND: The Advanced/MN motherboard does not use the FLUSH# signal.

STATUS: Not an issue.  Fixed in C2 stepping.

________________________________________________________________________________________________

6.  No shutdown after IERR#

WORKAROUND: See Note A following this table.

STATUS: Not Worked around. Fixed in C2 stepping.

________________________________________________________________________________________________

8.  Processor core may not serialize on bus idle

WORKAROUND: This errata was fixed with the B3 stepping of the 75/90/100 Mhz Pentium® Processor.  The Advanced/MN motherboard ships with post B3 CPUs and this errata does not apply.

STATUS: Not an issue.  Fixed in B3 stepping.

________________________________________________________________________________________________

9. SMIACT# Premature Assertion during Replacement Writeback Cycle

WORKAROUND: A motherboard is susceptible to this errata only if SMM space is  mapped over cacheable memory.  On the Advanced/MN motherboard SMM space is mapped over non-cached Video RAM, hence this is not an issue.

STATUS: This has been worked around.  Fixed in C2 stepping.

________________________________________________________________________________________________

10.  STPCLK# Deassertion Not Recognized for 5 CLKs after BRDY# Returned

WORKAROUND: The Advanced Power Management (APM) BIOS on the Advanced/MN  motherboard has been implemented in a manner such that STPCLK# is not used.

STATUS: This has been worked around.

________________________________________________________________________________________________

 11.  Future Pentium OverDrive® Processor FERR# Contention in Two Socket Systems

WORKAROUND: This errata is only relevant for motherboards which employ two sockets.  The Advanced/MN motherboard employs a single socket.

STATUS: This is not an issue. Fixed in C2 stepping.

________________________________________________________________________________________________

12. Code cache lines are not invalidated if snooped during AutoHALT or Stop Grant states

WORKAROUND: This errata was fixed with the B3 stepping of the 75/90/100 Mhz Pentium Processor.  The Advanced/MN motherboard ships with post B3 CPUs and this errata does not apply.

STATUS: This is not an issue. Fixed in B3 stepping.

________________________________________________________________________________________________

13. STPCLK# assertion during execution of the HALT instruction hangs system

WORKAROUND: The Advanced/MN  APM code has been implemented in a manner such that STPCLK# is not used.

STATUS: This has been worked around. Fixed in B3 stepping.

________________________________________________________________________________________________

14.  NMI or INIT During HALT Within an SMM May Cause Large Amount of Bus Activity

WORKAROUND: The Advanced/MN BIOS initializes Interrupt Vector Tables upon entering SMM.

STATUS: Worked around.

________________________________________________________________________________________________

16.  FRC mode miscompare due to uninitialized internal register

WORKAROUND: This problem only has implications in dual processor fault tolerant machines which employ FRC (Functional Redundancy Checking) on a cycle by cycle basis.  The Advanced/MN  motherboard is uni-processor and does not operate in this mode.

STATUS: Not an issue.

________________________________________________________________________________________________

Note A: Errata 6: Missing Shutdown after an IERR#

This errata describes certain conditions under which the CPU will not shut itself down after detecting an internal parity error.  Only a defective CPU will generate internal parity errors, therefore this errata only has relevance for systems with a defective CPU.

If a user has a defective CPU which encounters a parity error but is not affected by this errata (either because they have a C step CPU or they did not encounter one of the aggravating conditions) their CPU will immediately shut down, resulting in the termination of all system activities, and loss of any data which is in an indeterminate state.

________________________________________________________________________________________________

If a user has a defective CPU which encounters a parity error and is affected by this errata, (because they have a pre-C step CPU and encountered one of the aggravating conditions) then their system will continue functioning beyond the operation which caused the parity error.  In this case the system will still fail, due to the indirect effects of operating with an internal parity error (i.e. corrupted code execution). The end result is the same as if the system shutdown immediately due to the parity error.  A user with a CPU which is subject to internal parity errors will experience the same symptoms whether or not they are susceptible to this errata.

This errata has been fixed in the C stepping of the 75/90/100 MHz Pentium Processors.


PCIset errata

Locked PCI cycles by the A-1 Stepping of the 82437FX  TSC to a retrying PCI target do not function properly.

PROBLEM:  The A-1 stepping of the TSC component, the 82437FX, did not properly terminate locked cycles under certain conditions.  The improperly terminated cycle can result in a system lock-up.  Video cards are especially subject to this erratum.

Most video card vendors have rewritten their drivers based on our previous disclosure of this erratum so that the instructions that can cause this lockup are not used.  However, the default standard VGA driver for Windows '95 may cause this lockup under certain conditions.

WORKAROUND:  Copy the alternate Windows '95 VGA driver (named VGA.DRV) from the \drivers\display\vga subdirectory of the Windows '95 installation disk into the windows\system subdirectory on your hard drive.

STATUS:  This erratum has been fixed in the A-2 stepping of the 82437FX TSC component.

BIOS Issues

2982	Unable to lock resources to a specific card.

PROBLEM:  Using WINICU ver. 1.41 to lock resources does not work properly.  Lock does work if you simply want to lock in the resources that were assigned by the system default assignments at power up.  The problems arise if you use WINICU to alter the default assignments and then try to lock them.  This is a BIOS issue not a WINICU issue.

WORKAROUND:  None.

STATUS:  This will be fixed in a future release of the BIOS.

________________________________________________________________________________________________

3779	Entering time and date in system setup does not behave properly

PROBLEM:  To enter 00 as the hour in the CMOS setup program, a 1 or 2 must be entered as the most significant digit of the hour before a 0 can be entered as the least significant digit.  Then the 1 or 2 can be replaced with a 0.

WORKAROUND:  Enter 00 as described in Problem.

STATUS:  This issue is being investigated.

If you use the ICU to disable the on-board IDE interface, the interface will be enabled again if you reboot the machine (it will not stay disabled)

PROBLEM:  If you use the ICU to disable the on-board IDE interface, the interface will be enabled again if you reboot the machine (it will not stay disabled).

3010

If you use the ICU to disable the on-board IDE interface, the interface will be enabled again if you reboot the machine (it will not stay disabled).

WORKAROUND:  Use the setup utility to disable the on-board IDE, then it will remain permanently disabled.

STATUS:  This will not be fixed because of space limitations in the BIOS code.

________________________________________________________________________________________________

2913	The ICU does not support serial port IRQ sharing by the motherboard

PROBLEM:  The test scenario resulted in serial ports 1 & 2 sharing interrupt 3.  The ICU did not know how to handle it. Serial ports sharing an IRQ is perfectly legitimate.

WORKAROUND:  None at this time.  This may require a new revision of the ICU to support shared motherboard IRQ's.

STATUS:

2822	LanManager* 2.2 with IBM Token Ring II card needs a new driver

PROBLEM:  The failure mode is exhibited as a failure to connect to the network.  It will connect fine if the system is run in de-turbo mode.  This is resultant from a Token Ring driver that needs to be fixed.

WORKAROUND:  A new Token ring driver named Token.OS2 resolves this problem.  The driver is dated 9-4-94

________________________________________________________________________________________________

3525	IDE hard drives may not properly configure with Mitsumi IDE CD-ROM

PROBLEM:  When a Mitsumi IDE CD-ROM drive (model # CRMC-FX001DE) is configured as Slave on the primary channel (thus have a Hard disk as Master) and have a Hard Disk(s) on the secondary channel the device are detected incorrectly.  This is described as follows:

  1) Primary Master device detected as hard drive #0,

  2) Secondary Device detected as hard drive #2.

It appears that the Primary slave CD-ROM is partially detected as hard disk #1.

This causes problems later on when DOS is booted in that the Secondary hard disk is not accessible at all.

WORKAROUND:  Make sure to install the CD-ROM as a lower priority device than all hard drives.  If there are 3 IDE hard drives, the CD-ROM should be configured as a slave device on the secondary channel.

STATUS:  This will be fixed when ATAPI support is added to the BIOS.

________________________________________________________________________________________________

2946	QEMM's Manifest* 1.12 will not perform the expanded memory access test.

PROBLEM:  This failure is exhibited when the Advanced/MN is operating at 120 MHz. This test will run at slower speeds therefore it is likely that the test needs to be modified for higher speed CPU's.  Intel will notify QEMM.

WORKAROUND:  None.

________________________________________________________________________________________________

 2972	The 32 bit driver included with Windows 3.11 does not support large drives (drives over 504 MB)

PROBLEM:  Our BIOS will map large drives using LBA.  Windows does not understand the LBA algorithm.

WORKAROUND:  This issue can be corrected by editing the Windows system.ini file.  Find the "devicebitmap" statement and set it to devicebitmap=off.

________________________________________________________________________________________________

2641	The ATI Mach 32* card has PCI hold time issues

PROBLEM:  The ATI mach 32 card has some hold time requirements (the PCI spec. says that add-in cards do not need hold time).  The failure exhibits itself as a lock up on the PCI bus.

WORKAROUND:  ATI has revised their BIOS to fix the hold time issues.  Use BIOS revision 113-23000-110.

________________________________________________________________________________________________

3672	The ATI Mach 64 GX & CX add-in cards have some PCI hold time issues.

PROBLEM:  Some of the ATI  Mach64 GX & CX add-in card designs have a requirement for PCI hold time (the PCI spec. says that add-in cards do not need hold time).

WORKAROUND:  Some of the add-in cards in this family have a PAL implemented at location U51.  Boards with the PAL installed work.  Also, if the ATI device was produced at SGS then it is equivalent to the ATI DC stepping, this device works.

________________________________________________________________________________________________

3720	Quantum LP240S SCSI hard drive causes conflict with APM drivers

PROBLEM:  The Quantum LP240S SCSI hard drive installs a /APM switch on the command line for one of its drivers.  That switch prevented the hard drive from powering down properly.  If the drive was powered down with the hot key and then wakened with a DIR command the system would hang.

WORKAROUND:  Remove the /APM switch from the driver command line and use the APM drivers supplied with the Advanced/MN.

________________________________________________________________________________________________

2723	Quantum QLPS270 hard drives do not support Logical Block Addressing.

PROBLEM:  The Quantum QLPS270 hard drive inaccurately reports that it supports Logical Block Addressing (LBA).   The Advanced/MN by default is configured to auto-detect the hard drive and the modes it supports.  When the Advanced/MN detects the hard drive and  determines that the drive supports LBA it configures the drive for LBA, this will cause failures when attempting to use the hard drive.

WORKAROUND:  To avoid the failure scenario when using the QLPS270 hard drive, configure  the Advanced/MN to operate the hard drive in Standard CHS mode via the setup utility.

________________________________________________________________________________________________

3616	Windows 95 does not handle ECHS formatted correctly

STATUS:

________________________________________________________________________________________________

3988	Advanced/MN shows floppy errors running the Unixware* Unix peripheral stress test

PROBLEM:  The Unixware ver 2.0 peripheral stress test fails to run because floppy disks formatted by the test do not verify properly.  Investigation showed that this probem would only occur when the motherboard had more than 16 MB of memory installed.

WORKAROUND:  None.

STATUS:  This problem has been fixed by the Unixware floppy driver patch FD 2.01.

________________________________________________________________________________________________

3989 	The hardware stress test fails under Solaris* UNIX ver 4.2.

PROBLEM:  The SCSI tape drive portion of the Solaris UNIX 4.2 stress test fails with an IO error message.

WORKAROUND:  None.

STATUS:  This problem has been fixed  by the following updates, available from Sunsoft*:  The Jumbo Kernel Patch #101946-12 and Driver Update 8.


Functional Considerations

Functional considerations are usability issues that Intel has uncovered during product evaluation and compatibility testing.  These issues may be experienced by customers and therefore are documented in an effort help customers quickly identify known issues.  The items listed below are not considered Advanced/MN errata in that they do not reflect anything that is "broken" on the baseboard.

2563	ISA add-in Above board memory products are not supported

Impact:  Users will not be able to use Above board memory products.

________________________________________________________________________________________________

2948	De-Turbo is actually running at an effective speed of 23 Mhz

PROBLEM:  The intent behind de-turbo is to effectively reduce the system performance to that of an 8 MHz system.  The de-turbo feature currently reduces the system speed to 23 Mhz.  This is in accordance with the description in the Technical Product Specification.

IMPACT:  Although de-turbo is not running at 8Mhz it has still proved useful in our compatibility testing (running at 23 Mhz).  There are several operating systems listed in this functional considerations document that require our system be in de-turbo mode (23 Mhz) in order to successfully install.

________________________________________________________________________________________________

3733	Some Netroom* options are incompatible with APM.

PROBLEM:  If Netroom is used to virtualize the keyboard interrupt, the keyboard will not wake the system from sleep mode.

IMPACT:  The keyboard interrupt cannot be virtualized if the user wants to use APM.

________________________________________________________________________________________________

3671	CGA cards are not supported.

PROBLEM:  Although the Advanced/MN supports CGA emulation by VGA cards, it does not support CGA cards.

IMPACT:  CGA cards will not  work.

________________________________________________________________________________________________

3012	Mouse double click speed set to fast does not work.

PROBLEM:  This is under investigation.  Currently we believe that the problem is that users cannot click fast enough (now that we have bumped the CPU speeds up).  The mouse double click works fine when set to medium or slow.  We will continue to investigate this issue and drive it to resolution.

IMPACT:  Users will have to set the double click speed to medium.  In the mouse section of the control panel set the overall pointer speed and double click speed to medium (or slow).

________________________________________________________________________________________________

3078	Mouse cursor appears choppy in 16M color modes on S3 Trio32* with 1 Mb of graphics DRAM.

PROBLEM:  When the Windows environment is set into 640x480x16.7M mode, the system appears to take inordinately long to track mouse movements.  This is caused by bandwidth restrictions when only one MB of video memory is available.

WORKAROUND :  Increase video memory to 2 Mb.  The Trio graphics controller does not support hardware cursor in 16M color modes so mouse performance may suffer.

________________________________________________________________________________________________

2819	Unknown Device entry appears when using ICU ver 1.23.

PROBLEM:  An erroneous "unknown device" appears that has no resources assigned to it when using ICU version 1.23.  This entry appears because of the PCI bridge device support in the BIOS is not properly recognized by ICU v1.23.  Use WINICU version 1.41 which has support for PCI bridges and this false entry will not occur.

________________________________________________________________________________________________

3184	720K Floppies do not work with FastBack

IMPACT:  Users will not be able to use 720K floppies with FastBack.

________________________________________________________________________________________________

3719	APM hotkey does not work consistently with some older IDE hard drives.

IMPACT:  APM will not power down the hard drive consistently with one of these older drives.  Some drives that have been tested and found to be inconsistent are:

Maxtor MXT7131A

Maxtor MXT540A

Seagate ST3145A.

Sending scheduled fax with APM enabled does not work.

PROBLEM:  The system will not wake up to send a scheduled fax with APM loaded unless the DOSPM or Powerman drivers supplied with the system are installed for DOS or Windows 3.1 respectively.

________________________________________________________________________________________________

3247	Cannot run Powerman driver in standard mode for Windows.

PROBLEM:  The Powerman utility will only run in enhanced mode.

________________________________________________________________________________________________

3735	If DOS.PM is not loaded after reboot APM will be disabled

PROBLEM:  Certain disk management programs (DRVSPACE.EXE is an example) reboot the system at various times during their operation.  Before these reboots, the program edits the CONFIG.SYS and AUTOEXEC.BAT files and does not include DOS.PM.  APM will be disabled until program completes its work and reboots the system using the original CONFIG & AUTOEXEC files.

WORKAROUND:  None.

________________________________________________________________________________________________

3736	Full screen APM window resumes as icon after power-down

PROBLEM:  When the hot dey combination is used to power down the system during a full screen DOS session, the session resumes as an icon when the system is pwered on again.

Maximum Linear Frame Buffer size is 1 Mb

IMPACT:  ISA add-in cards requiring a Linear Frame Buffer larger than 1 Mb will not work properly.

________________________________________________________________________________________________

3483	S3 Trio64 video does not support 16M colors in 640x480 resolution

PROBLEM:  The S3 Galileo* utility will get chopped when running 640x400x16M on Trio64.   You will not be able to change anything because there are no "OK" or "Cancel" buttons.

________________________________________________________________________________________________

3716	Serial mouse does not wake monitor screen after APM shutdown.

PROBLEM:  Serial mouse activity is not recognized by the APM as a user event, so only the system board is wakened from power standby.  Use a mouse attached to the mouse port if you want the screen to be wakened by mouse activity.

General Product Information - Approved Vendor List - System Memory
System Memory

Table A-1 shows the possible memory combinations. The Advanced/MN will support both Fast Page DRAM or EDO DRAM SIMMs, but they cannot be mixed within the same memory bank. If Fast Page DRAM and EDO DRAM SIMMs are installed in separate banks, each bank will be optimized for maximum performance.  Parity generation and detection is NOT supported, but parity SIMMs (X 36) may be used. SIMM requirements are 70ns Fast Page Mode or 60nS EDO DRAM with tin-lead connectors.

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.

General Product Information - Approved Vendor List - Cache SRAM
Cache SRAM

Baseboards configured for 0 KB of L2 cache can be upgraded to either 256 KB or 512 KB of L2 cache by installing eight 24-pin 32k x 8 or 28-pin 64k x 8 3.3 volt SOJ SRAM (20 ns) devices into the provided sockets. The TAG socket accepts a 24-pin 32k x 8 5.0V SOJ SRAM (15 ns). The figure below shows the Pin 1 location for the TAG and data SRAM. To properly support an external clock frequency of 66 MHz (e.g.; the 100 MHz Pentium Processor), the data and tag SRAM must be 15 ns devices.

EXECUTIVE SUMMARY

This report is intended to supplement the Advanced/MN, also referred to as the Morrison, baseboard's Final Report, which provides detailed information about the full compatibility testing run executed on the Advanced/MN prior to its design release.  Sustaining runs are subsets of full compatibility runs; accordingly, this report builds on the testing conducted in that run.  This is the second sustaining report issued for this product.

The MORR__09 sustaining test run was conducted on Fab 3 baseboards with PBA# 634707-304 which featured Intel's Triton Process 650 chipset and 133-MHz Pentium® processors.  Additonal features of this baseboard included an integrated Crystal CS4234 sound chip and an onboard S3 Trio64 video controller.  The Morrison baseboards used in this series of testing were configured with 16-32MB of Fast Page DRAM system memory, 256K of Asynchronous, L2 cache, and AMI BIOS version 0.01.03.CA0 Beta 3.01.

There were 16 problems reported in the MORR__09 test run, seven of these issues originating in the Hardware Interpretability test lab.  A combination of Windows 95 and the onboard Crystal CS4234 sound chip on the Morrison baseboard caused a failure when using the MCS Stereo package.  A "General Protection Fault" error was displayed during Windows 95 validation.  Other issues included the failure of the PCI BIOS Confidence test, and the failure to validate the Orchid Kelvin EZ video card, Packard Bell TV4 and Reveal TV500 video expansion cards, and the Mitsumi FX-400 and NEC CDR-270 IDE
CD-ROM drives.  Additionally, there were two recurring problems regarding the NCR 8250S SCSI controller and the Matrox MGA II video card.

The Networks test area recorded four problems with the Morrison baseboard, two of which had been issues in previous test runs.  The Token Ring RPL (Remote Program Load) test would not boot from a remote server running LAN Server v4.0.  The system was tested using the IBM Token Ring 16/4 card with the RPL chip.  Despite several setting adjustments, it remained unable to boot.  Another issue was uncovered when the Morrison baseboard was configured as a server using Novell NetWare v4.10.  The baseboard failed two attempts to complete the NWTest; the first attempt resulting in a system lock and the second resulting in an "AB-END" (Novell ABnormal END).  There were two pre-existing problems discovered in the Network test area: a failure of the Xircom Pocket adapter, and errors in the CMOS setup utility.

Finally, the Morrison baseboard experienced difficulties in the Operating Systems test area.  Failures were reported in the Solaris UNIX v2.4 Stress Test and Network Stress Test, the UnixWare v2.0 Stress Test, and the  SCO UNIX v3.0 GUI environment.  An additional problem with the installation of SCO UNIX v3.0 was reported; however, a workaround allowed testers to install and continue testing.

Engineers were investigating resolutions to all issues at the time this report was written.  The problems found in this run are listed in two sections:  New Problems on page 21 and Existing Problems on page 35.  Additionally, this report lists functional considerations known to affect the baseboard in Appendix A, which begins on page 40.

CERTIFICATIONS:  Passing certification test results for IBM OS/2 v2.11, IBM OS/2 Warp v3.0, Windows for Workgroups v3.11and Windows NT v3.51 were sent to IBM or Microsoft for verification.

NEW TESTS INCLUDED IN THIS TESTING RUN:  This sustaining test run incorporated for the first time, the NSP (Native Signal Processing) BIOS Screen Tests.  These tests, which were added to the Hardware Interoperability test suite, were designed to assure that the product can support several features which are required on NSP compliant platforms.  The tests validate Plug 'N' Play, PCI, and APM support and perform several checks for Intel's Triton chipset.

NEW PRODUCTS INCLUDED IN THIS TESTING RUN.  A cumulative list of over 400 hardware, software, and network products tested on all versions of the Advanced/MN baseboard begins on page 13.  There were 36 new products tested for the first time on the Advanced/MN in this sustaining test run including Windows 95 and two upgraded versions of operating systems. The Compatibility Engineering Lab has introduced Sunsoft Solaris version 2.4 into the test suite in the UNIX test lab area, the Windows NT test area upgraded from Microsoft Windows NT v3.5 to v3.51.  Windows 95 testing has been introduced, using the latest beta version, in the Hardware Interoperability test area and the Software Applications test area.  New products have been identified with this symbol (), in the listing of products tested.


PRODUCT DESCRIPTION

This testing run was executed using Advanced/MN baseboards with PBA# 634707-304.  The run was conducted using baseboards with the Triton Process 650 chipset and 133-MHz Pentiums of the C2 stepping.  AMI BIOS 0.01.03.CA0, Beta 3.01 was used in this sustaining testing run.

The Triton chipset integrates a bus-mastering PCI IDE controller with two high performance IDE interfaces for up to four IDE devices.  Though the IDE controller was tested extensively in this run, its bus-mastering features were not. The baseboard's S3 Trio64 video controller option was tested in this run; some previous runs evaluated the S3 Trio32 option.  The Crystal sound chip is also a feature of this baseboard and the Crystal CS4234 was tested in this test run.  The Crystal CS4232 was tested in previous runs, including special audio testing in a previous feature test run.

This Advanced/MN baseboards used in this test run was configured with 256K of Asynchronous, direct mapped, write-back, L2 cache.  The Advanced/MN baseboard supports up to 512K of SRAM, which can be either Pipeline Burst or Asynchronous, and there is a no cache option.  The system comes with 8MB of memory standard, which is expandable up to 128MB using four 8MB x 32MB SIMM modules.  Both Fast Page and faster EDO DRAM are supported; Fast Page DRAM was tested in this run.  Notably, a baseboard containing both Fast Page and EDO DRAM was used in Windows NT and OS/2 Operating System testing in a previous test run.

The system's hardware capabilities are designed to take advantage of future operating systems, such as Windows 95. Features such as bus mastering IDE drivers, Plug 'N' Play, Advanced Power Management with application restart, soft-controlled power supply shutdown, and glitchless bi-directional audio are provided by software available from Intel. PCI and ISA expansion slots are supported by a connector on the baseboard designed to accept a riser card.

In addition to the tested options, the Baby-AT baseboard supports 75-, 90-, 100-, 120-, and 133-MHz Pentium processors. Most of these other options were tested in previous runs or will be tested in future Advanced/MN testing runs, and the broad compatibility of all of the board's major options will be confirmed using other members of the Triton-chipset-based Advanced family.

For more information about the specific Advanced/MN features tested in this run, see the FEATURE TESTING DESCRIPTION on the following pages.


FEATURE TESTING DESCRIPTION

The Advanced/MN baseboards tested by Compatibility Engineering were configured with 133-MHz Pentium processors.  The CE Lab tested the vast majority of the Advanced/MN's most important features, but not all of the board's many options could be evaluated

Tested Advanced/MN Features

  All five expansion slots.  Both ISA and PCI expansion slots are tested throughout the Hardware Interoperability Testing Area.  Each slot is systematically tested during Hardware Component Validations testing.

  BIOS support for Plug 'N' Play and PCI Auto-configuration.  The BIOS's "Plug 'N' Play" ability to configure (or configure around) PCI, PnP and ISA cards is part of the standard testing process in Hardware/BIOS testing.

  EDO DRAM System Memory.  High-end EDO DRAM SIMMs were tested in a previous Advanced/MN test run and a combination of both EDO and Fast Page DRAM has also been tested previously.

  Enhanced Parallel Port (EPP) Support.  The 8-bit send and receive capabilities of EPP parallel ports that allow the parallel port to perform as a true bus are evaluated in Novell NetWare testing using
the Xircom Pocket Ethernet Adapter III.

  Onboard audio.  The baseboard's onboard Crystal CS4232 sound chip was tested throughout all the Hardware Interoperability Testing Area.  It was specifically validated during Hardware Component Validation testing.  The Crystal CS4232 sound chip has been tested in a previous Advanced/MN test run including intensive special feature testing.

  Onboard video controller.  The baseboard's integrated S3 Trio64 video controller was tested throughout all the Hardware Interoperability Testing Area.  It was specifically validated during Hardware Component Validation testing.  The S3 Trio32 video controller has been tested in previous Advanced/MN test runs.

  PCI Bridge support.  A test card incorporating DEC's PCI bridge chipset was used to test baseboard support for the secondary and tertiary PCI buses in the Hardware Interoperability testing area.  PCI bridges are expected to become an increasingly popular PCI option on add-in cards.

  PCI Bus IDE.  The baseboard's integrated Triton PIIX PCI IDE controller is tested throughout all the Hardware Interoperability Testing Area.  It is specifically validated during Hardware Component Validation testing.

  Power Management.  Basic validation of the BIOS's ability to support Advanced Power Management is part of the standard testing process in Hardware/BIOS Testing.  Additionally, the Advanced/MN's power management capabilities were tested much more extensively with a special Advanced Power Management test run which was performed on the Advanced/MN.

  Using IDE hard drives greater than 535MB.  The CE Lab tests BIOS support for IDE drives too large to be automatically recognized by DOS.  In doing so, the Lab tests the IDE drive format options beyond Standard CHS.  Though these drives are tested throughout the Hardware Interoperability testing area, they are a focus of Hardware Component Validation testing.

Advanced/MN Features Not Tested

  3 Mode Floppy support.  At present, the CE Lab lacks the required hardware.

  Bus-mastering PCI Bus IDE.  At present there are no drivers available to test this feature of the Triton chipset.

  Extended Capabilities Port (ECP) support.  The CE Lab has not yet tested ECP support on the Advanced/MN product.

  IrDA Support.  The Advanced/MN's COM2 serial port can be configured to support an IrDA infrared module via a 5 pin header connector.  Support for IrDA compliant Infra Red interfaces is not yet tested by the CE Lab.

  Mixing different SIMM sizes.  The CE Lab tests with the SIMMs that come installed on the boards it is given by the design team.

  Mixing Parity and Nonparity SIMMs.  The CE Lab tests with the SIMMs that come installed on the boards it is given by the design team.

  Mode 3 & 4 IDE support.  At present, the CE Lab lacks the required hardware.

  Onboard Tape support.  At present, the CE Lab lacks the required hardware.

APPENDIX A -- Functional Considerations

The CE Lab does not expect these issues to affect most users' experiences with the baseboard or listed products. We report them expressly for the additional information they provide OEMs. Generally, these are third-party issues.

 (Problems are grouped by testing area and listed in alphabetical order within them.)

HARDWARE INTEROPERABILITY

Adaptec 1532P PnP SCSI drive controller

The 1532P PnP Adaptec PnP SCSI host adapter was a challenge to set up for proper operation on the Advanced/MN baseboard.  It also failed intermittently on many other baseboards tested by the iPTL.

With other baseboards, the SCSI drive controller would intermittently fail to flash its BIOS banner flag and initialize the hard drives.  In such cases, the system could not operate, for it could recognize no hard drives as being present.  On the occasions when the 1532P succeeded in flashing its BIOS banner flag, it operated normally during all tests.

This failure showed up throughout the Hardware Interoperability testing area.

Resolution:  These problems have been traced to flaws in the 1532P's operation, and the card has officially been removed from the iPTL's inventory.

Matrox MGA II video adapter

During Video Card Validations testing, the Matrox MGA II video card had problems if PCI Burst was enabled.

Resolution:  PCI Burst must be disabled if the Matrox MGA II video card is used with the Advanced/MN.

Onboard S3 Trio64 video controller

During DisplayMate testing, the onboard S3 Trio64 video controller failed in video mode 107 (1,280-by-1,024 resolution with 256 colors).

Resolution:  The latest BIOS revision of the S3 graphics accelerator no longer appears to support the "Set Logical Line Length" parameter of the IBM EGA/VGA and VESA SuperVGA standards, according to Sonera Technologies, the makers of DisplayMate.

Proshare ISDN

ProShare didn't work properly unless the drivers for the onboard sound controller were installed prior to ProShare being installed.

Resolution:  The drivers for the onboard sound controller must be installed prior to the ProShare software's installation in order for the combination to work properly.

System Deturbo

Landmark's System Speed Test v2.00 reported the 'Deturbo' speed of the 120-MHz Advanced/MN system as 29.84-MHz.  This speed was reported whether the Advanced/MN was deturboed via CMOS Setup or Hot-Key sequence.  This speed was also reported when the system was run at 120-MHz with cache disabled.  This speed was well outside the accepted 'Deturbo' range of 6-8 MHz.

When this test was run on a reference system with a 120-MHz processor, the System Speed Test reported a 'deturbo' speed of 7-MHz.

Resolution:  As documented in the Advanced/MN's technical product specification, "setting the processor to deturbo only slows [it] to the approximate equivalent of a 25-MHz clock, not the standard 8-MHz rate."

NETWORKS

Banyan VINES V5.54(0)

The Advanced/MN board had problems printing when it was used as a Banyan server. When Banyan VINES was installed as a file server on Advanced/MN and printing was attempted from a client, no printing occurred. This was repeated several times.

Banyan needed a "Key" attached on the parallel port in order for the serial number and options to be installed in the server software. When the key was installed (the normal configuration) no printing would occur when a client tried to print to a print queue. If the key was removed and the server software was not running, the test unit printed. If the key was reinstalled the test unit printed extraneous characters because bit 6 was loaded by the key.

Resolution:  In order to print from Banyan VINES, delete the parallel port key and print through DOS.

Advanced/MN Setup for Novell NetWare v4.10 Testing

After setup was run to make IRQs 3, 4, 5, and 9 available for use by ISA adapters, the Advanced/MN system displayed the error "Secondary IDE Controller Resource Conflict".

Running the ICU showed that the baseboard's Crystal CS4232 sound controller was allocated IRQs 9(2) and 15, instead of the typical IRQs 5 & 9.  The ICU indicated that MPU, the IRQ required by Windows for controlling audio, was taking IRQ 15 and the onboard sound controller's Sound Blaster emulation was using IRQ 9.  The secondary IDE conflict error occurred because IRQ 15 is normally reserved for use by the secondary IDE controller; without it, the secondary controller cannot operate.

When the above-mentioned resource allocation was made when the primary IDE port was used, the IDE drives were still accessible.

If the above sequence was followed when connected to the secondary IDE port, however, the same error was reported by the system, and the IDE drivers could NOT be seen in either the onboard setup or with DOS FDISK utility.  CMOS had to be cleared at this point.  It should also be noted that if either IRQ 5 or 9 was used independently the system would not display this error.

Resolution:  When the ICU, Windows 95, or CMOS Setup are used to reserve IRQs for use by ISA legacy devices, the other devices configured by the BIOS will be automatically disabled and not given resources.  In this case, the baseboard "gave up" use of the secondary IDE controller.  It is worth noting that though the client tests were conducted with the onboard audio enabled, the server testing on the Advanced/MN was conducted with the audio disabled.

Advanced/MN Setup in Peer-to-Peer Network Testing

Beta BIOS 1.02 reported the Advanced/MN's CPU clock speed to be 90-MHz in setup, but there was a 120-MHz CPU on the baseboard.

Resolution:  In order to be configured properly for 120-MHz operation, Switch 6 on the baseboard must be set to "2x."

OPERATING SYSTEMS

Microsoft Windows NT v3.5 Tape Test

The Windows NT 3.5 Tape Test took an extended period of time to run to completion.

The Windows NT 3.5 HCT suite contains three tape I/O tests, one each for QIC 117 (floppy controller), QIC SCSI, and SCSI DAT drives.  The tests use API calls to verify that the tape reads, writes, and positions the tape correctly.  There are several logical parts to the test, each of which tests different tape I/O functions.  Part of the test procedure consists of writing thousands of blocks of 1024 bytes.  Microsoft documentation indicates that each complete Tape I/O test should take about 4-5 hours when the test is run on a 486DX33.

Recently, it was noticed that these tests were taking much longer than expected.  It does not seem to matter which system board is used; the results are similar across a large number or platforms.  The tests are taking approximately 2-4 times longer than the Microsoft guideline.

The exact times for the tape tests on this board were:

                TAPE I/O (QIC 117).........07 hr. 57 min.

                TAPE I/O (SCSI QIC)........13 hr. 30 min.

System continually reboots after installing the ICU

The configuration manager (DWCFGMG.SYS) cannot be loaded into upper memory, it must be loaded into conventional memory.  If loaded into high memory, one of the failure symptoms may cause the system to continually reboot.  To correct, boot from a diskette, or with DOS 6 and above, press the <F8> key during boot up.


BIOS 1.00.04.BT0 SETUP and BOOT sequence changes

BIOS Setup Modifications

Two modifications have been made to the Phase III BIOS setup fields. The first modification is to minimize user , or OEM, input in the integration process by not requiring Pre-Delay and Time-out settings to be programmed.  The second adds the flexibility to explicitly pick the sequence of the available boot devices, and to allow for future expansion of a mulitboot environment.

Removal of Pre-Delay and Time-out:

These two settings were replaced with the BIOS's ability to detect a drives' presence, whether it is a Master or a Slave, by utilizing an interrupt detection scheme. The user no longer has to modify these values for slow, or high capacity IDE drives.  Changes made to the setup display are the removal of these two fields while no other fields have been added.

*** If you are experiencing an excessive delay during boot up please note the paragraph below:

The time it takes to boot the system may increase due to this new algorithm, and this delay is caused by some drives not correctly reporting whether a slave device truly exists. Excessive boot times of up to several minutes have been noted with certain system configurations due to this situation. In cases where there is no IDE slave device, the user can disable the IDE slave option in setup to decrease the boot time.

Boot Sequence Change:

Previous BIOSs have had the capability to select from only two logical boot devices; C, and A.  The sequence as to how they could be configured were; A then C, C then A, or C only, however, this has limited boot device flexibility. Future BIOSs will be capable of booting from CD-ROM.

In order to offer all the all the available boot devices, for the user to pick from, the boot device configuration will appear like the following example where each device in the boot sequence from one to four can be defined:

Boot Options Sub-Menu

First Boot device

Floppy:

Hard disk

CD-ROM   ;this feature will be released in future BIOSs

Network

Disabled

Second Boot device

Third Boot device

Fourth Boot device

The field controls the order in which the BIOS attempts to boot from the hard disk, floppy drive, Network resource, or CD-ROM drive when ATAPI support is added to the BIOS.

See BIOS 1.00.04.BT0 SETUP and BOOT sequence changes.


Installing SCO* UNIX* V3.0 or 5.0

Description: Users have reported keyboard response problems during installation of SCO* Unix*.  There have also been reports of keyboards and mice not responding while running the SCO* Open DeskTop.

The problem is caused by a keyboard timing loop issue in the SCO kernel.  The following patches to the kernel will resolve these problems.

SCO will be making a patch publicly available to resolve the keyboard problem during installation . This patch will be in the form of a new installation boot diskette image. This patch may be downloaded from the SCO website (http://www.sco.com/Support/) when it becomes available. The patch is also being made available from SCO via mail for users without Internet access.  SCO can be reached at 1-800-SCO-UNIX

SCO intends to release a revision of the OS which should include this patch.  In the interim the following patch may be used to resolve the keyboard response issue seen during installation.

Patch#1:  This patch will resolve a keyboard response during installation.  This patch requires that you have another platform with SCO UNIX V3.0 or V5.0 operating on it. This second platform is necessary to build a new installation floppy with the patch.

Make a writable copy of the installation floppy, then do the following:

# cd /tmp

# /etc/mount /dev/fd0135ds18 /mnt

# cp /mnt/unix unix.Z

# uncompress unix.Z

Now apply the keyboard patch to the kernel and copy it back to the floppy:

# _fst -w unix

* rd42dat+0x1e?h 0x25

^^ The default is 14 - Maximum is 0xff

rd42dat+0x1e: 0xd = 0x25

* $q

# compress -H unix

# mv unix.Z /mnt/unix

# sync

# /etc/umount /dev/fd0135ds18

If this fails, try increasing the 0x25 value until the problem is resolved.

The second issue with the mouse and keyboard not responding during operation of SCO OpenServer v5.0 can be resolved with the following patch:

Patch #2  This patch is to resolve keyboard and mouse lockup during operation of SCO OpenServer Release 5.0.

•	Go to single user mode

•	Change to the directory /etc/conf/pack.d/cn

•	Make a backup of the Driver.o file

•	cp Driver.o Driver.orig

•	Start the hex editor on the Driver.o file

 adb -w Driver.o

•	If you get the message "adb not found" use:

/etc/_fst -w Driver.o

•	At the * prompt type:

rd42dat+0x1e?w 0xe830

               	^^

This is a hex value which controls the length of a timing loop. Legal values for the timing loop parameter are 0xe800 to 0xe830.  The default is 0xe0d.  If 30 doesn't work, try the following:

        25

        20

        15

        10

        06

You will need to relink and reboot between each value.

•	adb should return the following:

rd42dat+0x1e:   0xe80d= 0xe830

•	At the * prompt type $q to exit adb

•	Change to /etc/conf/cf.d

•	Link a new kernel by typing

./link_unix.

•	If there are errors during the link process, restore the original Driver.o

•	Shut the system down and restart.

Introduction

The Intel Advanced/MN Low Profile baseboards and systems integrate the latest advances in processor, memory, and I/O technologies into a standard LPX form factor that provides the best combination of performance, price, and flexibility. It provides the ideal platform base for the increasing requirements of today's (and tomorrow's) desktop applications.

The flexible baseboard design will accept Pentium processors operating at 75 MHz, 90 MHz, 100 MHz, 120 MHz, and 133 MHz, and has the scalability to accept faster Pentium processors in the future. The processor is complemented by a second level write-back cache in either 0 KB, 256 KB or 512 KB configurations implemented using asynchronous SRAMs for cost effective performance. The memory subsystem is designed to support up to 128 MB of EDO DRAM (for improved performance) or Fast-Page DRAM in standard 72-pin SIMM sockets. A Level 5 Pentium OverDrive socket provides access to future processor enhancements

Advanced/MN provides a new level of I/O integration. Intel's  82430 PCIset chipset provides increased integration and improved performance over other chipset designs. An integrated Bus Mastering IDE controller provides two high performance IDE interfaces for up to four IDE devices (hard drives, CD ROM drive, etc.). A Crystal CS4232 Codec integrated onto the baseboard provides 16-bit stereo audio with enhanced capabilities such as full duplex operation to provide support for the increasing number of demanding multimedia applications. The National PC87306 Super I/O controller provides the standard PC I/O functions: floppy interface, two 16550 compatible serial ports with FIFO, one EPP/ECP capable parallel port, a Real Time Clock, and keyboard controller as well as support for an IrDA compatible infra-red interface. PCI and ISA expansion slots are supported by a connector on the baseboard designed to accept a riser card.

In addition to superior hardware capabilities, a full set of software drivers and utilities are available to allow advanced operating systems such as Windows* 95 to take full advantage of the hardware capabilities. Features such as bus mastering IDE drivers, Windows 95-ready Plug and Play, Advanced Power Management (APM) with application restart, soft-controlled power supply shutdown, and glitchless bi-directional audio are all provided by software available from Intel for the Advanced/MN platform.

The Advanced/MN Low Profile Desktop baseboard provides the foundation for cost effective, high performance, highly expandable platforms which deliver the latest in CPU and I/O technology.

Mini LPX Form Factor

The Advanced/MN baseboard is designed to fit into a standard LPX form factor chassis. Figure 1 illustrates the mechanical form factor for the Advanced/MN. The Advanced/MN mini-LPX form factor does not strictly adhere to the standard LPX guidelines in that the outer dimensions are 10" x 8.8" rather than 13" x 9". Location of the I/O connectors, riser slot, and mounting holes are in strict compliance with the LPX specification.

Technical Product Summary - Baseboard Design Exceptions - Front Panel Connectors
Front Panel Connectors

There is no front panel connector on the baseboard for a Turbo/Deturbo switch. The processor speed can be set either through a parameter in the CMOS Setup Utility, or from the keyboard (<CTL><ALT><+> = Turbo, <CTL><ALT><-> = Deturbo). Changing processor speed from the keyboard may be prohibited by the operating system, or when the processor is in protected mode.

Setting the processor to deturbo (or slow) only slows the processor to the approximate equivalent of a 25 MHz clock rate, not the standard 8 MHz clock rate.


Jumpers/Switches

There is no Color/Mono jumper/switch on the baseboard to specify Monochrome or Color video mode at boot, the BIOS will automatically detect the type of video card installed.

Also, there is no Flash write protect jumper/switch, the BIOS needs to be able to write to FLASH to support the Plug and Play features.


OverDrive Processor Support

The Advanced/MN will only support OverDrive processors compatible with the Type 5 CPU socket. Processors requiring a Type 7 socket or VRM are not supported.

Power Consumption


CPU

The Advanced/MN baseboard is designed to operate with 3.3 volt Pentium Processors, reducing the system power requirements. A patented on-board voltage regulator circuit provides the required 3.3 volts from the 5 volt tap provided by a standard PC power supply. The baseboard supports the Pentium processors at iCOMP index 615 \ 75 MHz , 735 \ 90 MHz, 815 \ 100 MHz, 1000 \ 120 Mhz, and 1110 \ 133 MHz. The Pentium processor maintains full backward compatibility with the 8086, 80286, i386™ and i486™ processors. It supports both read and write burst mode bus cycles, and includes a 16 KB write-back cache configured as separate 8 KB code and data caches. Also integrated into the Pentium processor is an advanced numeric coprocessor which significantly increases the speed of floating point operations, while maintaining backward compatibility with i486DX math coprocessor and complying to ANSI/IEEE standard 754-1985.


Performance Upgrade

A 320-pin Zero Insertion Force socket provides users with a Level 5 OverDrive processor performance upgrade path. An OverDrive processor being developed for use with this socket will provide performance beyond that delivered by the originally installed Pentium Processor.


Second Level Cache

The Pentium processor's internal cache is complemented by a 256 KB direct mapped write-back second level cache implemented with eight 20 ns 32kx8, 3.3v asynchronous SRAM devices and a single 15 ns 32kx8, 5v external Tag SRAM which provides support for up to 64MB of system memory. The Advanced/MN can optionally be manufactured with SOJ sockets to support a "no cache" configuration upgradable to 256 KB or 512 KB. See User Installable Upgrades for more details.

Note: Baseboards configured for a 66 Mhz external CPU clock (for Pentium processors at 100 or 133 MHz) require 15 ns data SRAMs and a 15 ns Tag SRAM.


Technical Product Summary - Board Level Features - System Memory
System Memory

The Advanced/MN baseboard provides four 72-pin SIMM sites for memory expansion. The sockets support 1M x 32 (4 MB), 2M x 32 (8 MB), 4M x 32 (16 MB), and 8M x 32 (32 MB) single-sided or double-sided SIMM modules. Minimum memory size is 8 MB and maximum memory size, using four 8M x 32 SIMM modules, is 128 MB. Memory timing requires 70 ns fast page devices or, for optimum performance, 70 ns EDO DRAM (note: if the CPU clock speed is 100/66or 133/66 MHz , EDO DRAM needs to be 60 ns, Fast Page can still be 70 ns). 36-bit SIMM modules may be used, but parity generation and checking is not supported.

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. 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. It is even possible to have Fast Page DRAM in one bank and EDO DRAM in the other, in which case each bank is independently optimized for maximum performance. Bank A only, Bank B only, or both banks may be populated. There are no jumper settings required for the memory size or type, which is automatically detected by the system BIOS. Tin lead SIMMs are required to be used when adding DRAM.

EDO DRAM


EDO DRAM

Extended Data Out (or Hyper Page Mode) DRAM is designed to improve the DRAM read performance to approximately the level of an asynchronous second level (L2) cache (EDO write performance is the same as FPM DRAM). EDO DRAM holds the memory data valid until the next CAS# falling edge, unlike standard fast page mode DRAM which tri-states the memory data when CAS# negates to precharge for the next cycle. With EDO, the CAS# precharge overlaps the data valid time, allowing CAS# to negate earlier while still satisfying the memory data valid window time.

INTEL PCISET  DESIGN CONSIDERATIONS


82437FX System Controller (TSC)

The 82437FX 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. The TSC comes in a 208 pin QFP package.


82438FX  Data Path (TDP)

There are two 82438FX components which provide data bus buffering and dual port buffering to the memory array. Controlled by the 82437FX, the 82438FX devices add one load each to the PCI bus and perform all the necessary byte and word swapping required. Memory and I/O write buffers are included in these devices. The TDP devices are 100 pin QFP packages.


82371FB PCI ISA/IDE Accelerator (PIIX)

The 82371FB provides the interface between the PCI and ISA buses and integrates a dual channel fast IDE interface capable of supporting up to 4 devices. The 82371FB integrates seven 32-bit DMA channels, five 16-bit timer/counters, two eight-channel interrupt controllers, PCI-to-AT interrupt mapping circuitry, NMI logic, ISA refresh address generation, and PCI/ISA bus arbitration circuitry together onto the same device. The PIIX comes in a 208 pin QFP package.

The Advanced/MN baseboard provides two independent high performance PCI IDE interfaces capable of supporting PIO Mode 3 and 4 devices for transfer rates of up to 16 MB/sec. The system BIOS supports Logical Block Addressing (LBA) and Extended Cylinder Sector Head (ECHS) translation modes as well as ATAPI (e.g. CD-ROM) devices on both IDE interfaces. Detection of IDE device transfer rate and translation mode capability is automatically determined by the system BIOS.

In the Windows 95 environment, a driver provided by Intel allows the IDE interface to operate as a PCI bus master capable of supporting transfer rates of up to 16MB/sec while minimizing the system demands upon the processor. In true multi-tasking operating systems like Windows95, the CPU bandwidth freed up by using bus mastering IDE can be used to complete other tasks while disk transfers are occurring, significantly improving performance.


INTEL PCISET  DESIGN CONSIDERATIONS

Intel PCISET  Memory Hole Limitation

Due the design of the Intel 82430FX PCISET  chipset, only one memory hole can be active at a time. The user can not set the Base Memory size to 512 KB and enable the ISA LFB at the same time.

Intel 82430FX PCISET  PCI Hold Time Requirement

The chipset provides less hold time than the earlier Neptune and Mercury chipsets on the PCI address and data lines, but still is within the PCI specification. (The PCI specification calls out a 0 ns minimum hold time.) Some PCI expansion cards do not meet this requirement, and in fact require more hold time than the 82430FX  chipset provides. Disabling PCI write bursting will sometimes enable these cards to function.

Detailed information on the PCIset is available in the Intel 82430 PCIset data sheet.


National Semiconductor PC87306 Super I/O Controller

Control for the integrated serial ports, parallel port, floppy drive, RTC and keyboard controller is incorporated into a single component, the National Semiconductor PC87306. This component provides:

•  Two NS16C550-compatible UARTs with send/receive 16 byte FIFO

- Support for an IrDA compliant Infra Red interface

•  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 (N82077) with 16 byte data FIFO (2.88 MB floppy support)

•  Integrated Real Time Clock accurate within +/- 13 minutes/yr.

•  Integrated 8042 compatible keyboard controller

Configuration of these interfaces is possible via the CMOS Setup program that can be invoked during boot-up. The serial ports can be enabled as COM1, COM2, IrDA, or disabled. The parallel port can be configured as compatible, bi-directional, EPP, ECP, or disabled. The floppy interface can be configured for 360 KB or 1.2 MB 5¼" media or for 720 KB, 1.2 MB (3-mode), 1.44 MB, or 2.88 MB 3½" media. Connectors for the serial ports, parallel port, PS/2 mouse and keyboard are located on the rear of the baseboard.

Keyboard Interface

PS/2 keyboard/mouse connectors are located on the back panel side of the baseboard. The 5V lines to these connectors are 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 or mouse. For ease of use, the system BIOS can detect and correct keyboards and mice plugged into the wrong PS/2 connector.

The integrated 8042 microcontroller contains the AMI Megakey keyboard/mouse controller code which, besides providing traditional keyboard and mouse control functions, supports Power-On/Reset (POR) password protection. The POR password can be defined by the user 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, emulating a 23MHz AT, and <CTRL><ALT><+> sets the system for turbo mode. Changing the Turbo mode may be prohibited by an operating system, or when the CPU is in Protected mode or virtual 86 mode under DOS.

•	<CTRL><ALT><defined in setup>: Power down (Stand By) key sequence takes advantage of the SMM features of the Pentium Processor to greatly reduce the system's power consumption while maintaining the responsiveness necessary to service external interrupts.

•	<CTRL><ALT><defined in setup>: Keyboard lock key sequence provides system security by blanking the screen and ignoring keyboard input until the BIOS User Password is typed. When invoked, the keyboard LEDs will flash to indicate that the User Password must be entered to unlock the system. This feature will not take effect unless the User Password has been set in the BIOS setup.


Real Time Clock, CMOS RAM and Battery

The integrated Real Time Clock (RTC) is DS1287 and MC146818 compatible and provides a time of day clock, 100-year calendar with alarm features and is accurate to within 13 minutes/year. The RTC can be set via the BIOS SETUP program. The RTC also supports 242byte batterybacked CMOS RAM in two banks which 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 configuration switch on the baseboard.

An external coin-cell style battery provides power to the RTC and CMOS memory. The battery has an estimated lifetime of seven years and is socketed for easy replacement.


IrDA (InfraRed) Support

Serial port 2 can be configured to support an IrDA module via a 5 pin header connector. Once configured for IrDA, the user can transfer files to/from portable devices such as laptops, PDA's and printers using application software such as LapLink. The IrDA specification provides for data transfers at 115kbps from a maximum distance of 1 meter.

A 5-pin header is provided to allow connection to a Hewlett Packard HSDSL-1000 compatible Infra-red transmitter/receiver.


S3 Trio Graphics Subsystem

The Advanced/MN baseboard comes standard with a S3 Trio32 SVGA graphics controller with 1MB of graphics DRAM upgradeable to 2MB. The graphics DRAM can be upgraded to 2MB by installing two 256kBx16, 70 ns SOJ DRAM devices in the provided sockets. Refer to Appendix A for suggested venders and part numbers. The Trio32 incorporates a 32-bit graphics engine with a 24-bit RAMDAC, dual programmable clock generators, and a high performance accelerator core in a single device. The on-chip RAMDAC/clock synthesizer is capable of output pixel data rates of 135 MHz providing non-interlaced screen resolutions of up to 1280x1024x256 colors at 75 Hz with 2MB of DRAM. Hardware acceleration for graphics functions such as BitBLTs with ROPs, 2-point line draws, trapezoidal and polygon fills, clipping and cursor support provide high performance operation under Windows and other GUI environments. In addition, a fast linear addressing scheme based upon DCI (Display Control Interface) reduces software overhead by mapping the display memory into the CPU's upper memory address space and permitting direct CPU access to the display memory. The Advanced/MN can optionally support the Trio64 controller which provides all of the same features as the Trio32 with additional performance supplied by taking advantage of its 64-bit graphics engine when 2MB of DRAM is installed.

The Advanced/MN supports the VESA feature connector for synchronizing graphics output with an external NTSC or PAL signal and a shared frame buffer interface to maximize multimedia performance. NOTE:  the VESA feature connector is default disabled. To enable the feature connector, run the utility FCON.EXE that is included with the Windows video drivers.  Also, if the VESA feature connector is enabled, only 1MB of video DRAM will be available for use.

The Advanced/MN also supports other VESA standards such as the VESA DPMS protocol to put a DPMS compliant monitor into power savings modes and the VESA Display Data Channel (DDC1) that permits transfer of monitor identification and resolution support data for ease of use.

Audio Subsystem (Optional)

The Advanced/MN baseboard features a 16-bit stereo audio subsystem as a factory installed option in some areas. The audio subsystem is based upon the Crystal CS4232 multimedia Codec and Yamaha OPL3 FM synthesizer. The CS4232 provides all the digital audio and analog mixing functions required for recording and playing of audio on personal computers. These functions include stereo analog-to-digital and digital-to-analog converters, analog mixing, anti-aliasing and reconstruction filters, line and microphone level inputs, and digital audio compression via selectable A-law / law, and full digital control of all mixer and volume control functions. Combined with the Yamaha OPL3 FM synthesizer, the CS4232 also provides support for four major sound standards including Adlib*, Sound Blaster* Pro 2.0, Windows Sound System and MPU-401 to meet all of the requirements of today's multimedia applications. The CS4232 also supports full-duplex operation which ensures support for future applications such as video conferencing.

The CS4232 includes a full Plug and Play ISA interface and is comprised of seven logical devices including the Synthesizer, Game Port, Sound Blaster, Sound System, MPU-401, CD-ROM and the CS4232 device itself. Each logical device is configured into the host environment using the ISA Plug and Play configuration methodologies. (Note: The CD-ROM port is not utilized on the Advanced/MN design as CD-ROM devices are supported via the IDE interface). The audio sub-system requires up to two DMA channels and one interrupt. The system can be configured to use either DMA channels 0, 1, or 3. The interrupt can be mapped to interrupt 5, 7, 9, 11, 12, or 15. Configuration of these resources can be done using a Plug and Play ISA Configuration Utility.

Wave Table Upgrade


Audio I/O Access

An audio I/O module available with the Advanced/MN containing all of the necessary audio jacks (Speaker Out, Line IN, Mic IN) and game port plugs into a 34-pin header connector on the baseboard. The audio connectors are 1/8" stereo jacks. An additional connector located on the audio I/O module allows routing of the audio jacks to the front of the chassis. The audio output is connected to the standard PC speaker to provide an output path that does not require external speakers. If external speakers are plugged into the attached I/O module, then the audio output is redirected to the speakers. Furthermore, if headphones are plugged into a front panel speaker jack, the audio is redirected to the headphones.


CD-ROM Audio Input

A four pin connector resides on the board (J9F1) for interfacing the audio stream from a CD-ROM reader into the audio sub-system mixer. This is needed to record from audio CDs or play music CDs. This connector is compatible with the typical cable that is supplied with CD-ROM readers for interfacing to audio add-in cards.


Audio Drivers

Audio software and utilities are provided via the foundation software CD for the Advanced/MN. A Windows setup program installs all of the software programs and utilities onto the system hard drive. Included in the audio software are DOS utilities that allow the user to play a CD-ROM, control sound volume and mixer settings, run diagnostics, and switch between Sound Blaster Pro and Windows Sound System modes. Windows drivers and utilities include the Windows sound driver, audio input control panel, audio mixer control panel, and a business audio transport utility.


Wave Table Upgrade

An eight pin header is provided to connect to a wave table upgrade card for richer sound quality in both DOS and Windows environments. The upgrade module is simply installed into a standard ISA slot with a small cable routed to the connector (J8H1).

Figure 3 - Audio connector locations


Expansion Slots

A riser connector of EISA form factor provides the capability to support up to two Bus Master PCI and up to five ISA expansion slots on the Advanced/MN baseboard. The PCI bus is fully compliant with the PCI 2.0 specification. To ensure that the lowest positioned slot can support a full length add-in card, the minimum height requirement for the lowest positioned slot on the riser card must be a minimum of 1.2" above the baseboard on either side of the riser connector.

Related Topics:

PCI 3.3 Volt Capabilities


PCI 3.3 Volt Capabilities

To maintain strict compliance with the PCI specification, the baseboard 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. Note: The on-board 3.3 volt regulator provides power for the CPU, PCIset and L2 cache only, not the PCI slots.


Baseboard BIOS

The Advanced/MN baseboard uses an American Megatrends Incorporated (AMI) Pentium ROM BIOS, which is stored in Flash EEPROM and easily upgraded using a floppy disk-based program. BIOS upgrades will be downloadable from the Intel Applications Support electronic bulletin board service. 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 baseboard 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. The initial production BIOS in the Advanced/MN with the Trio32 graphics controller option will be identified as 1.00.03.BT0. Boards with the Trio64 graphics controller will have BIOS 1.00.02.CA0. As BIOS updates occur the revision number will increase to 1.00.04.BT0, 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 Address		FLASH Memory Area
F0000H	FFFFFH	64 KB Main BIOS
EE000H	EFFFFH	8 KB Boot Block (Not FLASH erasable)
ED000H	EDFFFH	4 KB ESCD Area (Plug'n'Play data)
EC000H	ECFFFH	4 KB OEM Logo Area
E0000H	EBFFFH	48 KB Reserved for possible future use
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.


BIOS Upgrades

FLASH memory makes distributing BIOS upgrades easy. A new version of the BIOS can be installed from a diskette. BIOS upgrades will be available as downloadable files in the secure section on the Intel bulletin board.

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; or

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

The upgrade utility ensures the upgrade BIOS extension matches the target system to prevent accidentally installing a BIOS for a different type of system. 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 a 8 KB block of write protected recovery code in the Flash device.

Note: Before upgrading the BIOS, make a copy of the CMOS parameter settings. After upgrading the BIOS, enter SETUP and reset the CMOS parameters to the default values by hitting the <F5> key. Then re-enter the original settings. You must clear CMOS after a BIOS upgrade or unpredictable operation may result.


Setup Utility

The ROM-based Setup utility allows the configuration to be modified without opening the system for most basic changes. 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 switch setting on the baseboard can be set to prevent user access to Setup for security purposes.


PCI Auto-configuration

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 non-Plug and Play ISA add-in cards in the Setup utility. The PCI Auto-Configuration function complies with version 2.0 of the PCI BIOS specification.


ISA Plug & Play

The BIOS incorporates ISA Plug and Play capabilities as delivered by Intel Architectural Labs Plug and Play Release 1.0A (Plug and Play BIOS Ver. 1.0A, ESCD Ver. 1.02). This will allow auto-configuration of Plug and Play ISA cards, and resource management for legacy ISA cards, when used in conjunction with the ISA Configuration Utility (ICU). Copies of the IAL Plug and Play specification may be obtained via FaxBack (800) 628-2283, or via CompuServe by typing Go PlugPlay.


Shadow Memory

Shadowing memory is a technique that copies a block of memory from ROM to the same address in DRAM to improve performance. In the Advanced/MN, shadow memory is automatically enabled from C0000-C7FFF (video BIOS area), and from E0000-FFFFF (system BIOS area). Memory from C8000-DFFFF is not shadowed unless used for PCI or Plug and Play expansion card ROM space. ISA legacy card ROM space will not be shadowed, this may have a slight adverse effect on performance of these cards.


Power Management

The Advanced/MN BIOS supports power management via System Management Mode (SMM) interrupts to the CPU and Advanced Power Management (APM Ver. 1.1). The APM capabilities will allow the system to be put into a power managed Stand By state by:

1. Pressing a sleep/resume button on the front of the chassis

2. Entering an user configurable hot-key sequence on the keyboard

3. Expiration of the user configurable system inactivity timer

Stand By mode reduces power consumption to Energy Star levels by utilizing the power saving capabilities of the Pentium™ processor and turning off DPMS compliant monitors and hard drives. Stand By mode also allows the system to be responsive to external interrupts such as in-coming Fax's or network messages. Add-in cards supplied with APM-aware (v1.1) drivers can also be put into a power managed state for further energy savings.

The Advanced/MN also is supplied with a power management utility for Windows called Powerman. In addition to the features mentioned above, Powerman provides support for the system to wake up at scheduled times (such as delayed faxes), support for a user prompted password upon wake up, and support for turning the system completely off via a mouse click for systems equipped with a soft-off power supply. Powerman is supplied on the foundation software CD that is available for the Advanced/MN.


OEM LOGO Area

Advanced/MN supports a 4 KB programmable FLASH user area located at EC000-ECFFF. An OEM may use this area to display a custom logo. The Advanced/MN BIOS accesses the user area just after completing POST. Instructions and a utility for generating a logo file are available on the Intel BBS. Logo files can be flashed into the BIOS using the standard FMUP utility.


Security Features

Administrative Password

If enabled, the administrative password protects all sensitive Setup options from being changed by a user unless the password is entered.

BIOS User Password

A BIOS password feature provides security during the boot process. A password can be set using the Setup utility, and must be entered prior to peripheral boot or keyboard/mouse operation. For more details on how to enable, disable, or change the password, see the appendix.

If the password is forgotten, it can be cleared by turning off the system and setting the "password clear" switch to the clear position.

Setup Enable Switch

A baseboard configuration switch controls access to the BIOS Setup utility. By setting the switch to the disable position, the user is prevented from accessing the Setup utility during the Power-On Self Test or at any other time. The message prompting the user to press <F1> to enter setup is also disabled.


Connectors

Front panel connections

I/O connections

Back panel connections


Front panel connections

The Advanced/MN baseboard provides header connectors to support functions typically located on the chassis bezel:

•	System Reset

•	Power LED

•	Keyboard Lock

•	Hard Drive activity LED

•	Turbo LED

•	System Speaker

•	Auxiliary Fan

•	Infra-Red (IrDA) port

•	Sleep/Resume

•	Power Supply On

Sleep/Resume (J2A1-SL, J9C1-SLP)

This two pin header, when connected to a momentary switch, can be used to put the system into a power managed state (Stand By) that will reduce the system's power consumption. If the system is in Stand By mode and the switch is closed, the system will instantly "wake up" or resume full system activity. (System activity will also resume when an external interrupt, such as a keystroke or mouse movement, occurs.) When used with a power supply with a high efficiency rating, the Advanced/MN is easily capable of reducing the system power to below EPA Energy Star requirements. The function of the Sleep/Resume button can also be achieved via the keyboard with a hot key sequence (programmable using CMOS setup). This connector can be found in two locations on the Advanced/MN baseboard to minimize system cable requirements.

Soft Power Down (J8C1-PWS CNTRL)

When used with a power supply that supports remote power on/off, the Advanced/MN baseboard can turn off the system power via software control (Powerman for Windows or shutdown in Windows95). An APM command issued to the system BIOS will cause the power supply to completely turn off the system via the three pin "PWS Control" header connector. For example, Windows™95 will issue this APM command when the user clicks on the Shutdown icon. The "PWS CNTRL" connector is a Molex 2695 3-pin connector which features a security latch. Power can be restored via a front panel power button when it is connected to the "PWS" two pin header. To properly support this feature, the power supply is required to pull down pin 3 of the PWS Control connector. When this pin is pulled low, the system BIOS will recognize the presence of a supply that supports soft-off.

By implementing a dual-pole momentary switch from the power button to the "PWS/SLP" four pin header connector, both sleep/resume and power resume functions can be supported via a single button. In this configuration, pressing the button (closing the switch) while the system is active will put the baseboard into Stand By mode, pressing the button while in Stand By will cause the system to Resume to full operation. When the system has been completely powered off via software control as mentioned above, pressing the button will turn the system ON invoking POST.

Infrared (IrDA) connector (J2A1-IR)

Serial port 2 can be configured to support an IrDA module via a 5 pin header connector. Once configured for IrDA, the user can transfer files to/from portable devices such as laptops, PDA's and printers using application software such as LapLink. The IrDA specification provides for data transfers at 115kbps from a maximum distance of 1 meter.

Speaker (J2A1-SPKR)

The external speaker provides error beep code information during the Power-On Self Test if the system cannot use the video interface. See the appendix for more information about error beep codes.


I/O connections

The baseboard contains shroudless stake pin header connections for cabling the audio, floppy, and IDE interfaces. Figure 5 shows the locations of these connectors and the orientation of pin 1 on each.

Figure 5. I/O Connections


Back panel connections

The back panel provides external access to PS/2 style keyboard and mouse connectors integrated on the Advanced/MN baseboard. Figure 6 shows the general location of the keyboard and mice connectors.

Chassis

A slimline case gives the Advanced/MN Low Profile Desktop a sleek look − while four peripheral bays, two PCI slots, and three ISA slots offer the expandability required for traditional PC applications. A 200 watt power supply ensures the system can support installation of the maximum number of peripherals and add-in cards. The Advanced/MN also has been tested to ensure it meets stringent environmental requirements.


Peripheral Bays

Four peripheral bays offer ample expandability for add-in devices. The system provides two 5¼" half-height bays, one 3½" one-inch bay, and one 3½" 1.6-inch bay. Both 5¼" bays and one of the 3½" bays are accessible from the front panel. The final 3½" bay can be used for an internally-mounted hard drive, as well as to provide external access for an optional infrared transceiver/audio connector panel.

The two 5¼" bays also can accommodate a single 5¼" full-height drive.

Figure 7. Advanced/MN Peripheral Bays


Fan

The Advanced/MN has two fans to keep the system cool. One fan is located within the power supply and exhausts warm air out of the system. The second fan, located behind the card guide, provides airflow across the add-in cards and the CPU. The second fan receives 12 Vdc directly from the power supply.


Front Panel

Figure 8. Advanced/MN Front Bezel

The front panel contains a power-on LED and a hard disk access LED to provide visual system information. Access is also provided to the peripheral bays, as described above. The power control button is also located on the front panel. For this switch to be enabled, the back panel power on/off switch must be set to "ON". Depending on the current state of the system, this switch has different functions. These functions are listed below.

Expansion slots

The Advanced/MN has five expansion card slots as shown in Figure 9. One slot is a full length 16-bit ISA card slot, two are half length 16-bit ISA card slots, one is a full length PCI slot, and one is a half length PCI slot. The Advanced/MN riser card uses a custom edge connector to route PCI signals from the baseboard. The sixth I/O panel (directly above the keyboard and mouse connectors) is reserved for a custom audio I/O module.


Back panel

The back panel consists of the power supply fan, a 115/230 voltage switch, the system power-on/power-off switch, access covers for the expansion slots, PS/2-style keyboard and mouse connectors, two DB9 RS-232 serial ports, a bi-directional parallel port, and a video output connector.

Figure 9. Advanced/MN Back Panel.


Power Supply

A 200 watt switchable power supply is integrated into the Advanced/MN Desktop to provide power for onboard resources, add-in cards, and peripherals. A switch on the back of the system sets the Astec SA201 power supply to operate at either 90-132VAC (3 Amps AC) or 180-264 VAC (2 Amps AC). Table 5 lists the current outputs.

Note:  Maximum wattage consumption for the system is 120 watts.

External CPU Clock Speed (50/60/66 MHZ) - Switches 7 & 8

These switches set the CPU's external operating frequency at 50, 60, or 66 MHz. Default setting depends on the specific product code, see the table below for specific Pentium processor configuration information.


Internal CPU Clock Speed - Switch 6

This switch sets the internal CPU clock speed to either 3/2 (OFF) or twice (ON) the external CPU clock speed. Default setting is 3/2, (switch 6 = OFF).

Pentium Processor type	Switch 8	Switch 7	Switch 6	J9C1

Reserved	OFF	OFF	ON	CPU
60/120 MHz	OFF	ON	ON	type.
66/133 MHz (not tested)	ON	OFF	ON


Setup Disable - Switch 5

Allows access to CMOS Setup Utility to be disabled by setting switch 5 to the ON position. Default is for access to setup to be enabled (switch 5 = OFF)


Clear CMOS - Switch 4

Allows CMOS settings to be reset to default values by moving switch 4 to the ON position and turning the system on. The system should then be turned off and switch 4 should be returned to the OFF position to restore normal operation. This procedure should be done whenever the system BIOS is updated. When this jumper is in the ON position, the system BIOS will display the message "CMOS cleared by jumper". The default is OFF.


Password Clear - Switch 3

Allows system password to be cleared by moving switch 3 to the ON position and turning the system on. The system should then be turned off and switch 3 should be returned to the OFF position to restore normal operation. This procedure should only be done if the user or administrative password has been forgotten. Default is for this switch to be OFF.


L2 Cache Size - Switches 1 & 2

These switch settings must match the amount of L2 cache installed on the baseboard for proper operation.

L2 Cache Size	Switch 1	Switch 2
0 kByte	ON	N/A
256 kBytes	OFF	OFF
512 kBytes	OFF	ON


J5J1 - Recovery Boot Enable

Allows the system to boot in the event the system BIOS has been corrupted by moving the jumper from the default position of 1-3 to the 1-2 position.


J5J1 - ISA Bus Speed

Sets the ISA bus speed as either 1/6 or 1/8 of the External CPU Bus clock speed. The default depends on the specific board configuration. By installing the jumper between pins 5-7 the ISA clock speed will be equal to 1/8 the External CPU Bus clock speed. Some ISA cards may not function correctly if the ISA bus clock speed is set above 8.33MHz.

ISA CLK Speed

CPU External CLK Speed	1/6 speed 5-7 Not Installed	1/8 speed 5-7 Installed
50 MHz	8.33 MHz	6.25 MHz
60 MHz	10 MHz	7.5 MHz
66 MHz	11 MHz	8.25 MHz


J5J1 - Reserved

The stake pins 4, 6, 8 are reserved and should not have a jumper installed between any of these pins.


J9C1 - CPU Voltage Regulation

This jumper changes the output of the on-board voltage regulator:  1-3 = VR voltage level, 5-7 = VRE voltage level.  The VR voltage range is specified as 3.3-3.465V, the VRE range is 3.45-3.6V. Pentium processors that do not require the VRE voltage specification should use the VR setting. When upgrading your processor, be sure to consult the documentation for the voltage requirements, an incorrect setting may damage the processor.

Inactivity Timer

This allows you to set how many minutes the system must be inactive before it enters power managed mode. The range is 0 to 255 minutes. The default is 10 minutes.

Hot Key

This allows you to enter a hot key that, when pressed while holding down the <Ctrl> and <Alt> keys, will cause the system to enter power managed mode. All alphanumeric keys, punctuation, and spaces are valid.

The Hot Key field is used to define a key which when entered will cause the APM BIOS to ask an APM (Advanced Power Management) aware Operating Systems to go into immediate power managed mode. There will be some delay, but the speaker will issue a single tone.

If there is a User Password in effect, then upon going into power managed mode the Num Lock, Caps Lock, and Scroll Lock LEDs on the keyboard will flash on and off, indicating to the user that the system is in Secure Mode. In this case the correct password will have to be entered before the user regains control of the system. This password will not be echoed to the screen nor will a carriage return be required. This is true whether the screen is active or inactive at the time the password is entered. The following table describes how the Power Down hot key interacts with the Security Hot Key.

	Power-Down Hot Key Entered	Security Hot Key Entered
Power-Down Hot Key Only Enabled	System powers down (can include screen blanking if enabled) Powers up when any key/mouse activity is detected	N/A
Security Hot Key Only Enabled	N/A	System Secure Immediately LEDs flash Input accepted when password typed
Both Hot Keys Enabled	System Secure Immediately System powers down (can include screen blanking if enabled) LEDs flash Input accepted when password typed Powers up when any key/mouse activity is detected	System Secure Immediately  System powers down (can include screen blanking if enabled) LEDs flash Input accepted when password typed Powers up when any key/mouse activity is detected


Plug and Play Configuration Subscreen

Configuration Mode

When selected, this brings up a dialog box that allows you to set how the BIOS gets information about ISA cards that do not have plug and play capabilities. The options are Use Setup Utility and Use ICU (ISA Configuration Utility). The default is Use Setup Utility.

If Use ICU is selected, the BIOS will depend on run-time software to ensure that there are no conflicts between ISA boards with plug and play capabilities and those without. Only "Boot With PnP OS" will be visible if this parameter is set to Use ICU, none of the rest of the items in this subscreen will be visible.

If Use Setup Utility is selected, the BIOS will depend on the parameters in this subscreen to avoid conflicts.  "Boot With PnP OS" will not be visible if this parameter is set to Use Setup Utility.

Boot With PnP OS

When selected, this brings up a dialog box that allows you to specify how the Plug and Play devices are configured.  The options are None, Other, and Windows 95.  The default is Windows---95.  If set to Other or Windows 95, the BIOS will activate only those Plug and Play devices required to boot the system.  The other Plug and Play devices will be configured by the operating system.  If set to None, the BIOS will use both the CMOS settings and the information stored in the ESCD area to configure all the Plug and Play and PCI devices in the system. (The ICU is used to store information into the ESCD area.)

ISA Shared Memory Size

When selected, this brings up a dialog box that allows you to specify a range of memory addresses that will be directed to the ISA bus rather than on-board memory. The options are Disabled, 16 KB, 32 KB, 48 KB, 64 KB, 80 KB and 96 KB. The default is Disabled. If this is set to Disabled, "ISA Shared Memory Base Address", below, will not be visible.

This field should be set to Enabled only when a non Plug and Play ISA card (legacy card) is used that requires non-ROM memory space.  LAN cards that have on-board memory buffers are one example of this, video capture cards that have video buffer memory are another.

By default, allocation of upper memory is as follows.  Memory from C0000-C7FFF is automatically shadowed.  (This memory range is typically reserved for Video BIOS.)  Memory from C8000-DFFFFh is initially unshadowed.  The BIOS will scan this range for any ISA expansion card BIOSes that may be present and note the location and size.  The BIOS will then autoconfigure the PCI and Plug and Play devices, shadowing the ROM requirements (other than video) into the area above E0000h until that area is full.  It will then assign additional PCI and Plug and Play expansion cards to the area between C8000h and DFFFFh.  If an ISA legacy card has non-ROM memory requirements, the autoconfigure routine may write into an area that is needed by the ISA expansion card.  The ISA Shared Memory Size parameter is used to signify to the autoconfigure routine that this block of memory is reserved and should 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 DRAM memory to allow faster access to the code and achieve higher performance.)

ISA Shared Memory Base Address

When selected, this brings up a dialog box that allows you to set the base address for the ISA Shared Memory. The options are C8000h, CC000h, D0000h, D4000h, DC000h and D8000h. The default is C8000h. This setting may affect the ISA Shared Memory Size item. The value entered in the ISA Shared Memory Size item cannot extend into the E0000h address. For example, if a size of 64K was selected, options D4000h, and D8000h will not be available.

IRQ 3, 4, 5, 7, 9, 10, 11, 12

When selected, this brings up a dialog box that allows you to set the status of the IRQ. The options are Available and Used By ISA Card. The default is Available. The auto-configuration code looks here to see if these interrupts are available. If an interrupt is available, the auto-configuration code can assign the interrupt to be used by the system. If your system contains an ISA agent that uses one of these interrupts, select Used By ISA Card for that particular interrupt.

Some of these interrupts may not be displayed if they already have been assigned to other peripherals, such as IRQ 3 and IRQ 4, which are normally used by the serial ports, and IRQ 12 for the mouse port.

Note: If PCI add-in cards are used, all but one IRQ can be set to Used By ISA Card; one must remain available in order for PCI cards which use interrupts to function correctly.

Note: IRQ 14 and IRQ 15 will not show up as user available. If the on-bd IDE controller is not used, these interrupts are available for use by ISA cards, even though they do not show up in the list above. These interrupts can not be used for PCI cards.


Security SCREEN

The objectives of the BIOS security system are to:

1.	Keep unwanted individuals from accessing the computer.

2.	Limit the fields that can be accessed in the CMOS Setup Utility program.

3.	Allow the computer to boot while unattended and still be secure.

4.	Set up a hot key to invoke the security system immediately.

The security system is implemented using two passwords in tandem, a User Password and an Administrative Password. The level of security available is dependent on whether one or both passwords are set and which password is used to enter the system. It is assumed that if the Administrative Password is used, it is controlled by a central corporate information services or security organization and that the Administrative Password and User Password will have been set prior to the end user receiving the system.

To meet each of the objectives above, use the following procedures:

1.	End user sets/resets User Password depending upon whether the Administrative Password is in effect.

2.	Administrative Password and User Password were set prior to end user receiving system; no action required by end user.

3.	End user sets User Password then Enables Unattended Start. If User Password had previously been set, user Enables Unattended Start.

4.	End user sets User Password then Enables Security Hot Key. If User Password had previously been set, user Enables Security Hot Key.

Password in Effect	Password Needed at Boot?	Password Needed to Access Setup?	Able To Access All Setup Fields?	Able To Set Unattended Start?	Able To Set Security Hot Key?
User only	Yes	Yes	Yes	Yes	Yes
Administrative only	No	Yes	Yes	No	No
Both -- User password used	Yes	Yes	No	Yes	Yes
Both -- Admin password used	Yes	Yes	Yes	Yes	Yes
No password enabled	No	No	Yes	No	No

Appendix I - BIOS Recovery
Appendix I − BIOS Recovery

The Advanced/MN incorporates the AMIBIOS in a Flash memory component. Flash BIOS allows easy upgrades without the need to replace an EPROM. The upgrade utility fits on a floppy diskette and provides the capability to save, verify, and update the system BIOS. The upgrade utility also provides the capability to install alternate languages for BIOS messages and the SETUP utility. The upgrade utility can be run from a hard drive or a network drive, but no memory managers can be installed during upgrades.

Using the upgrade utility

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.x 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.

Note: Before upgrading the BIOS, make a copy of the CMOS parameter settings. After upgrading the BIOS, enter SETUP and reset the CMOS parameters to the default values by hitting the <F5> key. Then re-enter the original settings. You must clear CMOS after a BIOS upgrade or unpredictable operation may result.


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 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.


Appendix J - BIOS Error messages and Beep Codes
Appendix J − BIOS Error messages and Beep Codes

Errors can occur during POST (Power On Self Test) which is performed every time the system is powered on. Fatal errors, which prevent the system to continue the boot process, are communicated through a series of audible beeps. Other errors are displayed in the following format:

ERROR Message Line 1

ERROR Message Line 2

For most displayed error messages, there is only one message. If a second message appears, it is "RUN SETUP". If this message occurs, press <F1> to run AMIBIOS Setup.
