Capacitor Change, Heat Sink, Processor Stepping - est 4/95
Capacitor Change, Heat Sink, Processor Stepping − est 4/95

Class I

There will be a change in the capacitor at C1K5 for video Hsync and C1K8 for video Vsync.  The change is to facilitate certain monitor types, as these monitors do not currently sync dependably on this system.  The problem has been noted on NEC 3FGE and  NEC 3V monitors. The capacitors will be changed from the current 470 pF value to 220 pF..

This ECO is also planned to discontinue use of the tall heat sinks and move exclusively to low profile heat sinks for the i486 processors.

This ECO will  move exclusively to the B2 stepping of the 486 DX2-66 processor.


Heatsink, Video Controller, Transguard, CPU Stepping Changes, Drivers, BIOS, Keyboard Controller;  Mar 95

Class I

The specified Cirrus Logic 5430 will be built onto Classic/PCI Low Profile boards. Classic/PCI Low Profile boards have been built with the Cirrus 5434 due to lack of availability of the 5430.  To support the 5430 part instead of the 5434, the resistor at R3J1 is removed and a 22 ohm resistor is added at R3J3. Video driver version 1.22c is currently available as a requirement for this ECO. The version 1.22c drivers require the use of BIOS 1.00.05.AZ0. The 5430 part requires the use of both the 1.00.05.AZ0 BIOS and 1.22c video drivers.  The Dear Customer Letter about the 5434 substitution will be removed.

Low profile heatsinks will be installed on i486 processors, except the SX-25 version which does not require a heatsink. This change allows use of a full-length ISA card in the bottom slot of the riser, if the customer is using a 5V CPU and is willing to remove the Voltage Regulator heat sink. Instructions on how to remove the heatsink have been published.   The high profile heat sinks will continue to be used as an alternate due to current lack of availability of the low profile heatsinks.  The change over to using all low profile heatsinks will come in a subsequent ECO.

The keyboard controller code changes the mechanism for handling the A20 gate and the mechanism for password protection. There are no form, fit, or functional changes at the board level to this part. The new part is S-spec SZ962.  The current controller will continue to be used as an alternate due to availability.

A transguard will replace a capacitor at location C1C3 to protect the system from ESD hits at the front panel LEDs. A transguard is a special type of diode which protects against ESD. This part change allows the system to pass Intel's ESD level specification of 20kV.   The current component will continue to be used as an alternate due to availability.

The resistor at location R8C7 will change to 1K-ohm for improved EMI suppression.

Intel's components group is shipping the B-2 stepping of the 66 MHz Intel DX2 processor, so the DX2-66 version of this board will ship with the B-2 stepping. The current stepping will continue to be used as an alternate due to availability

The changes above result in a modification to the baseboard AA and PBA numbers for ECO #1860D.

General Manufacturing Process Change: No-Clean Flux, Q3-Q4, 94

Intel Products Group (IPG) will change our manufacturing process to use a no-clean flux (NCF).  Current water soluable fluxes require an aqueous cleaning process that generates waste water that must be treated to remove lead before being discharged to municipal drains. The use of NCF will eliminate this cleaning step.

NCF use is widespread in the electronics industry and a significant amount of research has been published confirming the absence of harmful effects to board reliability.  In addition, IPG manufacturing conducted an extensive qualification test using both our internal environmental/reliability lab and an external contract lab. The tests were designed to expose any solder defects that might be present. The test results demonstrate that the presence of flux residues left on the finished product using the no clean process causes no corrosion or other ill effects. In addition, no impact to board cosmetics was noted.

The change to NCF will occur on a manufacturing site-by-site basis through out the Q3-Q4 time frame. There will be no part number change to the products to indicate this change has occurred.


Minor PBA Changes, Oct 94

The SL jumper at location J5A2 changes to default setting 2-3 to correct an errata.  Your system will work properly with either setting, but you will need to set the jumper correctly for clean flash BIOS updates and to upgrade your processor.  See the errata in this file for details.

The documentation structure for the PBA and AA levels needs to be altered to improve the manufacturing flow through our factories. There will be no functionality differences at the AA level after the change.

The anti-static bag for the board will change to a smaller size.

The changes above result in a modification to the baseboard AA and PBA numbers for ECO #E01746.

•	An ECP compatible option has been added to parallel port configuration.

•	DOS "mode comX: 19" now supported.

•	Chipset is now disabled before DOS boots.

•	Correction of CMOS clearing problem if reset directly following POST .

•	LOGO now allows user code to be flashed in and executed at various points in POST.

•	Setup changed to enable/disable user option ROM code scanning.

•	Onboard video may be disabled when a CGA card is installed.

•	Cirrus video BIOS version 1.2.

•	96k ISA shared memory option available via Setup.

•	Keyboard port is switched back to the primary port when a keyboard and mouse are not found.

This new BIOS is required with the 1.22c video drivers and the 5430 video controller to operate properly. The release version BIOS is now available by calling the Applications Support hotline.


Release 4, Mar 95

There will be no official release of the revision 4 BIOS to the general public due to logistical problems.  Revision 5 contains all enhancements and fixes scheduled for release 4.  Minor fixes and enhancements were made from beta 4 to release 5 including:

Fix for CMOS clearing on reboot problem.

Fix for extended parallel port option working properly.

Added ECP to parallel port options in BIOS.

Other minor functional changes to correct beta problems.

Note: If your system contains version 4 of the BIOS it should be updated to version 5!


Release 3, Oct 94

This is a preview to the changes being incorporated into the Phase II BIOS.  This BIOS will be used on all new products and backported to some existing products.  This BIOS will be release 3, 1.00.03.AZ0.  It is available on the BBS under file name 10003AZ0.EXE.

Video BIOS included in this release is version 1.00e.

The Release 3 BIOS will no longer support the SCSI NR (No ROM) PCI Add-in Card

Setup Changes

o	New, more user-friendly interface.  Layered interface functions more like standard applications with better screen layout for easy viewing.  Similar functions are grouped onto screens or menus for easier configuration.

o	On-line help available for most setup fields.

o	Administrative password function allows all but Time/Date and User Password selections to be modified only by the system administrator.

o	New screen layout allows for more descriptive field text.

o	New screen layout permits field and option text to be translated without having to use cryptic abbreviations.

Password Changes

o	Both User and Administrative passwords are available.

o	Passwords have been extended to seven (7) characters instead of the current six (6).

Language Support

o	Multi-language support is now available.

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

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

Hard Disk Changes

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

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

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

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

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

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

Windows 4.0  Plug and Play

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

o	Setup menus are still TBD.

APM 1.1

o	Advanced Power Management that supports both the APM 1.0 and 1.1 specifications.

o	Standby and Suspend are handled as like events allowing power down from OS/2 Control Panel.

o	Critical 1.1 calls are allowed even if the OS connects as 1.0.  This allows POWER.EXE to run in 1.0 while a custom Windows driver takes advantage of full 1.1 compatibility.

o	Setup menus are still TBD.

New Int 15h Extensions

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

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

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

Other Changes

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

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

Approved SIMM List, Classic/PCI Low Profile

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

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

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

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

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

IMPORTANT NOTE

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

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

APM Software Installation

Overview

Installation and Use for Windows 3.1 Users

Installation and Use for MS-DOS 6.xx Users

Installation and Use for Other Operating Systems


Overview

This system provides energy-saving power management capability and includes BIOS support for the Advanced Power Management (APM) standard.  APM provides a method to control system power management of the CPU, IDE hard drive(s), and VESA DPMS-compliant video monitor.

In addition to the built-in APM BIOS features, an operating system-specific APM software driver is required in order to utilize the power management capabilities of the system. The APM drivers included with both MS-DOS 6.xx and Microsoft Windows 3.1 are discussed in more detail in the INSTALLATION section.

The APM feature provides a method for you to control whether you want the PC to go into Power Saving state, and how and when you want your PC to do this.  When your PC goes into the Power Saving state, you can choose how much power you want to save.  You can configure the PC to power down the hard drive(s), and to power down the video into three different states.  The Power Saving state is set to operate after a set time of inactivity chosen by you, in the same way as a windows screen saver, and can be configured under DOS or Windows.  You can configure the Power Saving options using either the BIOS setup, or the Windows setup utility. A hotkey option is included with Windows to enable you to immediately power down your PC via the keyboard, and when this option is used with a Windows screen saver, it lets you put your PC in a power down, password protected state when leaving it unattended.


Installation and Use for Windows 3.1 Users

Enabling power management for Microsoft Windows 3.1 requires a three step installation process: 1) configuring Windows from DOS to include the APM driver via the Windows SETUP program, 2) installing the Hot-Key application software using the SETUP.EXE program on this diskette, and 3) enabling the BIOS APM features as desired via the Flash BIOS Setup utility.

Step 1:  Enabling Windows 3.1 APM Driver

From the DOS prompt, change to your WINDOWS directory, and type SETUP to invoke the Windows Setup utility (Do not use the "Windows Setup" Icon in your Windows "Main" program group).  Change the 'Computer:' setting to 'MS-DOS System with APM'.  Follow the on- screen instructions to save changes and exit Windows Setup.

Step 2:  Installing the Hot-Key Application

Run the SETUP.EXE program included on this diskette.  From MS-DOS, type 'a:setup.exe' and Windows will be automatically invoked as part of the installation process.  From Windows, select 'File', 'Run', and type 'a:setup.exe', and press "OK". Following setup of the Hot-Key application, you must exit Windows to complete the installation process.

The SETUP program will install a power management Hot-Key icon in the Windows Control Panel group.  Double clicking on the icon allows selection of a Hot-Key combination that can be used to place the system into the Power Saving state.

Step 3:  Enabling BIOS APM Features

Reboot the system and press the <F1> key when the BIOS sign-on message appears to enter the Flash BIOS Setup utility.  From the main Setup menu, select the 'Advanced' screen, then select the 'Power Management Configuration' option, and press the <Enter> key.  Enable the desired APM options and exit to the main Setup menu by pressing <Esc>, then <F10> followed by a 'Y' to save the BIOS changes and reboot the system.

Click BIOS APM options to see details on the BIOS Setup.

The system can enter the Power Saving state in one of two different ways: automatically via time-out or instantly via a Hot-Key combination.

Inactivity Time-out

In BIOS setup, you can set a time-out period to put the system into Power Saving state. The system will be automatically shut down after recognizing inactivity for the specified time period, in the same way as a screen saver works.

HotKey Combination

To set up your HotKey combination, double click on the "Control Panel" icon in the Windows "Main" group, and then double click on the "APM Hot-Key" icon in the "Control Panel" group. Press the key you want to use to put the system into the Power Saving state, and then press "OK". Now you can put your system into the Power Saving State at any time by pressing the "Ctrl", "Alt" and your chosen key at the same time.  If a screen saver is installed when the Hot-Key combination is depressed, then the screen saver will be invoked before the system enters the Power Saving state.  If a screen saver password is enabled, then the user is prompted for a password when the system "wakes up" from its Power Saving state.

Most users will probably want the screen saver to activate before the system powers down, since otherwise the screen saver will never appear.  To activate the Screen saver before power down, the screen saver timeout should be set to a shorter time than the BIOS APM timeout value.


Installation and Use for MS-DOS 6.xx Users

Enabling power management for MS-DOS 6.xx involves the loading of a device driver program called Power.exe, which will occupy 5Kb of memory. If you are a Windows user, and have installed the Windows power management drivers as above, it is not necessary to install power management drivers for MS-DOS. The procedure below is for users who run only DOS, and is a two step installation process:  1) installing the MS-DOS APM software driver using the INSTALL.EXE program on this diskette, and 2) enabling the BIOS APM features as desired via the Flash BIOS SETUP utility.

Step 1:  Enabling MS-DOS 6.xx APM Driver

From MS-DOS, type 'a:install.exe' to invoke the installation utility.  Follow the on screen instructions to install the APM driver.

Step 2:  Enabling BIOS APM Features

Reboot the system and press the <F1> key when prompted following the BIOS sign-on message to enter the Flash BIOS Setup utility.  From the main Setup menu, select 'Advanced' screen, then select the 'Power Management  Configuration' option, and press the <Enter> key.  Enable the desired APM options and exit to the main SETUP menu by pressing <Esc>, then <F10> followed by a 'Y' to save  the BIOS changes and reboot the system.

Click BIOS APM options to see details on the BIOS Setup.

Power Saving states can be activated automatically following a user-specified period of system inactivity.  The system "wakes up" from a Power Saving state when a keyboard, mouse, network, serial port, or disk drive interrupt is detected.

WARNING: If the BIOS user password feature is enabled, then the user must enter the user password when the system "wakes up" in order to unlock the keyboard. Although the keyboard lights will flash to indicate that the password must be entered NO PASSWORD PROMPT WILL APPEAR ON THE SCREEN. For this reason it is recommended that the BIOS user password is disabled when Advanced Power Management is enabled.

The system can enter the Power Saving state automatically via time-out.

Inactivity Timeout

In BIOS setup, you can set a time-out period to put the system into Power Saving state. The system will be automatically shut down after recognizing inactivity for the specified time period, in the same way as a screen saver works.

Hot-key Combination

If the HotKey is selected in BIOS setup, the Power Saving state may be invoked by pressing your chosen HotKey combination.


Installation and Use for Other Operating Systems

Refer to the operating system user's guide for more information on APM support and driver configuration.

APM Testing

Power Management testing of the Classic/PCI LPX exercised all the latest BIOS power management options.  Testing consisted of pairing the system under test with different video cards, hard drives and monitors and evaluating the combinations' ability to power down with communication hardware and software, six operating systems and as a client on seven networks.  All told, a total of 74 different products were tested; as no list of "green" equipment to be tested was provided, standard Lab hardware was used.  (The Lab's collection includes both green and non-green equipment.)  A power meter measured the wattage drop evidenced when the systems under test went into the various power-saving modes.

Tested BIOS Setup options include:

IDE Drive Power Down

VESA Video Power Down — Standby

VESA Video Power Down — Suspend

VESA Video Power Down — Sleep

Inactivity Time for both IDE drives and VESA video

Hot Key combinations to effect sleep mode

Software Drivers Used in Testing included:

DOS*	OS/2	Windows

POWER.EXE	APM.SYS	APMAPP.EXE

APMDLG.CPL

POWER.DRV

POWERMAN.386

VPOWERD.386

*The DOS POWER.EXE driver was also used in network client testing.

Some EOL Quantum Drives Fail

2/6/95

Problem:

Failures have been noted on some Quantum  "Thunderbolt" models, 270AT or 540AT with "TB" in the part number.  The failure seen is that the drive boots DOS fine, but when entering Windows, an error message is displayed, "Group Windows\applicat.gro misconfigured, reconfigure."  (the group named may vary).  Not all drives of this model are affected, and moving this drive to another system can remove the error message.  The problem is related to noise on the data cable, the drive's firmware revision, and the speed of the PCI IDE interface.

Resolution:

The Thunderbolt drive is no longer in production from Quantum.  If you have a failing drive, contact your drive supplier and request the Maverick drive instead.


Does not Fit in StackRACK

1/20/95

The Classic/PCI Low Profile chassis does not fit into Intel's StackRACK.  The StackRACK was designed for the Classic E system, which used a different chassis.  That chassis was 16.3" wide, and the Classic/PCI Low Profile system is 17.2" wide.  The width causes interference with the sides of the StackRACK.  There are no plans to change either the StackRACK nor the Classic/PCI Low Profile chassis.


Maximum number of PCI slots on a Riser is 2

12/16/94

The maximum number of PCI Slots on an Classic/PCI Riser card is 2.  The Aries Chipset only allows 2 PCI slots; on the Classic/PCI Expandable Desktop, three PCI slots are allowed because of special circuitry on the motherboard.  This circuitry does not exist nor is there room to add it to this motherboard.


Cirrus Video Drivers Do Not Support Standard Mode Windows

11/22/94

The Cirrus Logic Video drivers were written and optimized for performance, so they were written to use a linear address for the display buffer and to run in protected mode.  The drivers will only run in enhanced mode and not in Windows Standard mode.


Full Length ISA card in bottom slot

11/4/94

Here is Intel's recommended solution for customers who would like to install full-length add-in cards in the lowest slot of the ISA/PCI riser in our Classic/PCI Low Profile system. These instructions apply only to configurations using Intel486 and IntelDX2 processors. They do not apply to configurations with the IntelDX4 processor.

Intel's low profile chassis features a secondary fan that provides improved airflow over the processor and voltage regulator. As a result, we are able to take the following actions:

• Ωε ωιλλ χηανγε αλλ οφ τηε Ιντελ486™ προχεσσορ ηεατσινκσ ον ουρ Χλασσιχ/ΠΧΙ πλατφορμσ το  λεσσ τηαν 0.25∀ ηιγη. Τηισ πρεϖεντσ τηε προχεσσορ ηεατσινκ φρομ ιντερφερινγ ωιτη τηε λοωεστ σλοτ ον τηε ρισερ χαρδ. Τηισ αππλιεσ το μοδελσ ιν τηε χυρρεντ Χλασσιχ/ΠΧΙ προδυχτ λινε.We will change all of the Intel486 processor heatsinks on our Classic/PCI platforms to  less than 0.25" high. This prevents the processor heatsink from interfering with the lowest slot on the riser card. This applies to models in the current Classic/PCI product line.

•	The voltage regulator heatsink may be removed in configurations using the 5 volt Intel486 SX-25 processor through and including the IntelDX2 66 MHz processor. This removes the VR heatsink obstruction of the lowest slot on the riser card. (Please note that the IntelDX4 processor uses 3.3 volts and requires the use of the voltage regulator heatsink. The VR heatsink must not be removed in IntelDX4 processor configurations.)

IMPORTANT NOTE

Removal of the voltage regulator heatsink is recommended ONLY for Intel system level products using 66 MHz IntelDX2 or lower-rated processors. Intel has thoroughly tested circuit operation in our chassis, which uses the secondary fan. Since many other low profile chassis available in the marketplace do not provide a secondary fan for CPU cooling, we recommend that board-level customers DO NOT remove the voltage regulator heatsink, unless they have performed a complete thermal evaluation in their application. In addition, you will be unable to install an OverDrive processor, unless the heatsink is re-installed and the add-in card removed.

If removal of the voltage regulator heatsink is appropriate for your application, please follow the instructions below.

CLASSIC/PCI LOW PROFILE SYSTEMS

Removal of Voltage Regulator Heatsink

IMPORTANT NOTE

Removal of the voltage regulator heatsink is recommended ONLY for Intel system level products using 66 MHz IntelDX2 or lower-rated processors. Intel has thoroughly tested circuit operation in our chassis, which uses the secondary fan. Since many other low profile chassis available in the marketplace do not provide a secondary fan for CPU cooling, we recommend that board-level customers DO NOT remove the voltage regulator heatsink, unless they have performed a complete thermal evaluation in their application. In addition, you will be unable to install an OverDrive processor, unless the heatsink is re-installed and the add-in card removed.

To remove the Voltage Regulator heatsink, begin by ensuring that the power to the system is OFF. Insert a  small, flat tool (such as a flat screwdriver tip or similar) between the metal of the heatsink and the black plastic portion of the heatsink support. This is located very near the baseboard edge, between the letters B & C in the silk-screen.

Apply a light twisting pressure to increase the gap between the plastic and the heatsink, then pull up firmly on the heatsink.

Save the heatsink so it will be available if you later decide to install a future processor that requires the use of a heatsink.


Motherboard Screw Torque setting

11/4/94

In our systems manufacturing line, our motherboard screws are installed with a torque setting of 8 inch-pounds.


Clarification:  3.3V Power Connector on the Motherboard

11/4/94

If a customer connects 3.3V power to the 3.3V power connector on the motherboard, that 3.3V power will be delivered to the proper 3.3V pins on the PCI connector on the riser card, and 5V will continue to be delivered to the ISA and PCI connectors from the standard power supply.  The 3.3V power will not go anywhere else, including the CPU on the motherboard.


Cirrus Drivers Load Big

10/19/94

The Classic/PCI Low Profile system integrates Cirrus Logic's GL543x video circuitry on the motherboard.  The current version of the Windows 3.1 driver, version 1.10b, is considerably larger when installed than the standard VGA and SVGA drivers that ship with Windows 3.1.  If the customer is seeing out of memory problems in Windows with the Cirrus 1.10b drivers, then the standard VGA or SVGA drivers should be used.  This was also true of the first drivers shipped with this product, the 1.10a drivers.

Cirrus Logic is aware of the current situation with the size of their drivers, and the issue is being addressed.


Battery Backup is soldered down

10/19/94

The Classic/PCI Expandable Desktop uses a Real Time Clock (RTC) function provided by a Dallas DS12887 device. The board requires no external support because the lithium battery, quartz, and support circuitry are integrated into the DS12887.  There are no provisions to provide off-board battery support, and the device is not removable--it is soldered onto the board.


APM Installation Notes

10/13/94

The Advanced Power Management software for the Classic/PCI Expandable Desktop and Classic/PCI Low Profile systems are slightly different from those for the Premier/PCI product line.  The complete installation instructions are included elsewhere in this help file, but some notes may make it easier to get going.

To install under Windows, you do not need to install Powerman.exe.  There are three basic steps to install under windows:

1)	under Windows setup, make sure your operating system is "DOS with APM".

2)	install the green software on Windows.  The software is located on a green-colored disk shipped with the system or pulled off the BBS.

3)	run BIOS setup to enable Power Managment and to set the desired amount of power down.

Notes to consider:

•	Make sure your CPU is SL-enhanced.  All CPUs shipped on this product are SL-enhanced, but if you upgraded your CPU, you may need to check.

•	Make sure your peripherals are all green, including the IDE drive, video controller and monitor.  A monitor may be damaged if  the power-down software is used but the monitor is not "power managed".

•	Make sure you have the correct version of EMM386.exe.  If your EMM386.exe is old, copy the version off the green disk.

•	We have seen an issue where the video driver for another video card needs to identfy the monitor attached.  By changing the setting to a green monitor type, the software will then allow the system to enter power save mode.

•	Windows APM does not run with 32-bit disk access.  Windows will try to warn you if you do try to set 32-bit disk access with APM installed.  This is a function of Windows, not of the hardware.


Advanced Power Management and Network Cards

12/16/94

Users of power-managed systems may experience difficulties when using network

cards that do not recognize Advanced Power Management (APM). The system may fail

to stay in sleep mode or may disconnect from the network while in sleep mode.

The AMI BIOS on current Intel boards and systems relies on the power mangement

routines in the Operating System (DOS, OS/2, etc.). These routines define when

and how the platform will wake up.

Specific issues that have been noted using the "DOS with APM" setup for Windows

include:

  - the platform never enters sleep mode because the network polls the card

    repeatedly, never allowing the system to time-out.

  - the network disconnects the system during sleep because the system is not

    responding to network requests

In order to take complete advantage of Advanced Power Management, both the

system and its peripherals must support APM. This includes ALL devices which

generate interrupts. For example, the video controller and the monitor must be

DPMS-compliant, the IDE hard drive must support power-down modes; and all add-in

cards (including networking cards and modems) must be APM-aware.

There is a non-APM solution for users who want to take advantage of sleep mode,

but who have network cards that are not APM-aware. The POWERMAN.EXE utility

available on the Intel Applications Support BBS (916-356-3600, OEM Platforms /

Classic R) will provide this functionality for all Classic/PCI and Premiere/PCI

systems.


No 3½" Filler Panel available

Due to the design of the Low Profile bezel and the "window pane" look of the floppy bay opening, there is not a filler panel available to replace the floppy itself.  There are no plans to add this feature.


BIOS Automatic Detection of Hard Drives

The AMI BIOS for this product supports automatic detection of the IDE Hard drives installed.  The BIOS probes the drive to determine the manufacturer and the factory default drive parameters.  If the drive was formatted using other drive parameters, the BIOS will detect the drive as factory default and then the drive will not boot or be able to be read.  If you formatted the drive using settings other than the factory default, you must set the drive parameters manually in the Setup screen.


Without Monitor, Cirrus Initializes Either Color Or Mono

The Cirrus 5430 and 5434 controllers are designed such that if a monitor is not connected to the monitor port, the controller will initialize in either color mode or monochrome.  There is no default mode.


Can't keep on-board video enabled if add-in card installed

The BIOS searches for off-board video during the power up routine, and if it finds an add-in card video, the BIOS then disables the on-board video.  There is no setup option to change this routine.


Don't mix vendors of cache

If you experience problems with your system, make sure that all the cache data components are of the same vendor (the Tag and Dirty Bit may be from other vendors).  Mixed vendors may work acceptably, but may also cause problems, and we have seen problems resolved by changing the data cache to one vendor.


Console Redirection through Serial Port

The Classic/PCI Low Profile board does NOT support connection of a terminal to the COM port to communicate with the BIOS and system.  The BIOS looks for scan codes from the keyboard, and most terminals provide ASCII through a com port.  Scan codes represents a matrix inside the system that translates keyboard strokes in a table into characters.  Therefore, the Classic/PCI Low Profile board will not support any terminal that does this ASCII code sending.  The only known system that will work with the Classic/PCI Low Profile board is an older AT&T terminal that transmits scan codes.There are no plans to add this functionality to the Classic/PCI Low Profile board.


EMM386 Dated 3/25/94 Required

Boards with the Aries chipset running DOS requires EMM386 dated 3/25/94.  If DOS 6.21 or later is installed on your system, you have the correct EMM386.  This file is found on the green diskette shipped with the system and on the Cirrus Drivers diskette, and is embedded in the two zipped files and posted to the Intel Applications BBS.


Write Back Cache "Dirty Bit" Explanation

The Dirty Bit is needed for a write back cache implementation only.  An understanding of Write Through versus Write Back cache is needed to fully explain the function of this bit.

Write Back Cache is different from Write Through Cache in that Write Back cache allows cache write hits to modify the cache line without updating DRAM or main memory.  Write Back Cache includes a bit called the "dirty" or modified bit.  This bit is set if the cache location has been written with new information which is more recent than the corresponding location in main memory.  If a subsequent read miss occurs and the line being fetched needs to fill the cache location that is currently being occupied by the modified line, the cache controller must write the modified cache line back to main memory.  Thus coherency is maintained.


Wake Up, Then Reset

Intel recommends that a system in power managed mode ("sleep" mode) be brought back to full power before a soft reset is issued.  This action is recommended because the soft reset runs a shorter BIOS  test, and the hard drive may still be spinning up when the BIOS tries to determine its type.  If the hard drive has not fully spun up and the BIOS probes to find the drives, the BIOS may fail to recognize the drive.  The BIOS would find the drive on a second reset, but it is better to restore full power to the drive and system before issuing the soft reboot.


AIP Super I/O Compliance Causes Failures On A Few 5¼" Floppy Drive Manufacturers

ISSUE:

The current spec for two AIP signals, DRVSEL and MOTENA, is 12 ma.  There are certain floppy drives that use 150 ohm pullups on those signals, requiring about 33 mA.  (150 ohm was originated in 8 inch drives requiring a 10 foot cable).  Originally the 82077AA/SL series drove 40mA.  The 12mA spec change began with the 82078 floppy controller, though the part still drove 40ma.  The drive strength of the AIP has been reduced to meet the current spec.  This list of floppy drive Manufacturers are those that Intel believes to require a larger buffer for these two signals.

Drives that use 150 ohm resistors	Drives that use 1K ohm resistors
(they won't work in this system)	(Drives that work)
Panasonic	Teac
Toshiba	NEC
Chinon	Mitsumi
	Epson
	All combo drives (so far)


Color Jumper has no effect

The color jumper on early fabs does not do anything.  In later fabs the silkscreen for this jumper will be removed.


APM Under Windows And 32-Bit Disk Access

Microsoft recommends that 32-bit disk access not be used with APM machines (a warning is posted to this effect when enabling 32-bit access).  Problems seen with 32 bit disk access turned on and  power management active range from system lockups to disk corruption.

To Disable 32-bit Disk Access, go to the Windows Control Panel Icon.  Click on the 386 Enhanced Icon, click the Vertual Memory Button, click the Change Button, and then you will see a check box marked "Use 32-bit Disk Access".  Make sure the box is unchecked and this will disable the function.

In short, 32-bit disk access should be disabled when using APM under Windows.

Problem

According to the Wangtek customer support line the 5099en tape drive is not reliable on 66 MHz processors.  The tape drive has been noted to have problems on the 486DX2-66 Classic PCI systems.

Resolution

Wangtek suggests upgrading to a newer drive.


NCR 3299-K440-V004 Has Timing Incompatibilities

Problem:

There are timing incompatibilities between the NCR 3299-K440-V004 keyboard and this keyboard controller used on this system.  The nature of the problem is such that the keyboard is not recognized on boot up but will operate normally under certain circumstances once the system is running.  This makes it impossible to use the CMOS set up.  In the version 3 BIOS this problem makes the keyboard unusable under DOS, but with the version 5 BIOS it is usable in DOS.

Resolution:

No know work around at this time.


Diamond Viper SE Video Board Fails

Problem:

When used in windows with the Diamond Viper SE video driver the Diamond Viper SE video board will not work properly.  The problem is manifested via distorted graphics in windows.  There is a known incompatibility with the Weitek P9100 chip used on this video board and the Aries chip set in burst mode.  The problem is related to the Weitek chip accepting invalid data after a burst cycle.  Weitek has provided a work around but will not supply a solution.

Resolution:

The work arounds are any of the following:

1)  Obtain a program from Weitek that will inhibit the Aries chip set form enabling burst mode.

2)  Turn off cache in the CMOS set up.

3)  Use only the standard video drivers supplied by Microsoft for windows.


Norton Diagnostics fails Vertical Retrace test

2/3/95

Problem:

Semantic's Norton Diagnostics version 8.0 has a video test called Vertical Retrace.  This test will fail on the Classic/PCI Low Profile, but the board is OK.  There is a problem in the test software which causes this failure.

Resolution:

Semantic intends to correct this problem in an upcoming release.

Resolution:

Use driver version 1.06  or higher to operate properly in this system.  Contact your supplier of the D-Link card for this software.


GXE64 PCI Video Card by #9

10/19/94, updated 12/28/94

Problem:

When using a GXE64 PCI Video card by #9 under Windows and at higher resolution then VGA mode, black boxes appear instead of the cursor, icons are missing, and sizing buttons are missing.

Resolution:

Edit the SYSTEM.INI file, find the [DISPLAY] heading, and add the following line:

APERTURE-BASE=31

This "hardwires" a memory window in the last 64MB block of the second gigabyte of memory address space.  Note this could cause memory conflicts with other PCI devices.  If so, adjust the Aperture-Base settings downward until a working setting is discovered.


APM using OS/2 v2.11

When using OS/2 version 2.11 and Advanced Power Management, the system will not automatically power down unless the user enables the Advanced Power Management every time the system boots.  This feature worked properly under OS/2 version 2.1.  IBM has fixes available, files are BRAPPK.1DK and BRAPPK.2DK.  Consult IBM to obtain these fixes.

Installing Windows NT on a Quantum Large Capacity Drive

Microsoft® position using large format drives on Windows NT

Microsoft's official position is that Windows NT v3.1 does not support Logical Block Addressing (LBA) mode and disk drives that are larger that 1024 cylinders.  The next release of NT, Daytona Beta 2, fixes this problem and is scheduled for release as Windows NT v3.5

Test Results

Intel testing has found the results of using large drives largely unpredictable; some work and others do not.  All tested worked using the following procedure.  You have two options when installing NT 3.1 on the Quantum drive:

1.	Use CMOS Setup Autoconfigure; Standard CHS.  This will result in 1-n partitions (depending on how you tell NT to divide the disk) with a total useable disk space of 472 Mb.

2.	Use CMOS Setup Autoconfigure; LBA Enabled. This will result in 2-n partitions (you must have at least 2) with total useable disk space of 515 Mb.

Windows NT installation procedure (from CD-ROM) to maximize use of Quantum drive space

1.	Use a new drive.  If not new, set the CMOS to Autoconfigure, LBA Enabled; boot from a floppy; run FDISK and remove all existing logical drives and partitions.

2.	Set CMOS to Autoconfigure, LBA Enabled.

3.	Begin NT Setup.  Use all defaults -- Express install

4.	Create two partitions (at least).  I used 125Mb for the C: drive and 390 Mb for the D:. The smaller the C: drive, the faster the formatting.  I do not know the minimum size.

5.	Install and format NT to the C: drive.

6.	The system will re-boot and continue its Setup.  Sometimes a Trap or Checksum error occurs here.  This is a known bug when using PCI/IDE.  Microsoft has provided the attached driver ATDISK.SYS.  If you are using ISA/IDE, you do not need this driver.  The driver is included in Daytona. Copy the driver into C:\WINNT\SYSTEM32\DRIVERS and write over the old driver.  Reboot.

7.	When Setup is complete, the system will automatically re-boot again.  If a trap or Checksum error occurs, follow the instructions in Step 6.

8.	Boot the system from a DOS floppy.

9.	Copy the attached ATDISK.SYS driver into C:\WINNT\SYSTEM32\DRIVERS.

10.	Format the D: drive (and others).

11.	Re-boot from the C: drive.


Solaris HCT

The Solaris version 2.1 Hardware Certification Test (HCT) will fail on this platform during the CD-ROM configuration  portion of the stress test.  The CD-ROM test passes as a stand-alone test and only fails during the stress test.  Solaris version 2.4 corrects this problem.


Znyx ZS312 PCI Ethernet Adapter

The Znyx ZS312 PCI Ethernet adapter needs driver version 2.0 or later in order to properly initialize in the Classic/PCI Expandable Desktop.


Diamond Viper PCI Video Card

Problems have been noted with Diamond Viper's ROM BIOS versions prior to v3.12.  Diamond Viper customers with downrev firmware can obtain a free  upgrade EPROM by calling Diamond Tech Support @ (408) 736-2000.


Matrox MGA II PCI Video Card

There are problems with Matrox drivers version 1.41 and earlier with both the Classic PCI Expandable Desktop and Low Profile boards.  Be sure to use newer drivers.


OS/2 Installation using PCI SCSI

When using PCI SCSI to install OS/2, the SCSI drivers must be copied to the OS/2 diskette in order for the OS to see the card.  The current OS/2 installation does not have support for PCI SCSI.


Adaptec 2940 PCI SCSI Requires Firmware v1.11

Problems were seen with earlier firmware revisions on Adaptec 2940 PCI  SCSI card.  Firmware revision 1.11 corrected these problems.


LanManager installation with OS/2

Testing has shown that when OS/2 V2.0 is loaded on the system, Lan Manager v2.2 will not install.  To work around this, install Lan Manager with the system in deturbo mode.


OS/2 Load From CDROM Needs Minimum 8MB Memory

Intel has seen problems on many different systems under this scenario:   only 4MB of memory installed, trying to install OS/2v2.1 from CDROM with the CDROM connected to a PCI SCSI card.  There are three workarounds for this problem recommend by IBM:

1.	Create diskette images from the CDROM and install

2.	Copy the necessary files off the CDROM temporarily to the hard disk and install from there

3.	Add an additional 4MB of memory to install then remove once install is complete


GXE PCI Video Adapter by #9 needs Driver v3.15 or later

Earlier versions of the Windows drivers for the #9 GXE PCI Video adapters showed distortion in the Windows wallpaper and multimedia applications.  These are fixed by drivers v3.15 available from #9.


Adaptec 1532 Plug and Play SCSI (ISA) Adapter

If using the Adaptec 1532 Plug and Play ISA card, set the floppy to disabled using the appropriate switch block (see Adaptec's manual).  This will allow the motherboard's floppy to continue to function properly.


Old Revs of EtherExpress16 have Problems

Some problems have been identified with old EtherExpress16 adapter cards (manufactured before June of 1992) and the Classic/PCI Expandable Desktop or Low Profile, including failures to boot to a floppy and the AIP not being initialized.  The same early EtherExpress 16 adapter cards caused video problems with older systems.  The EtherExpress 16 adapter card has been modified to alleviate these conflicts.

MODIFICATION

This modification for the EtherExpress 16/16TP was initiated in early June, 1992.  By looking at the serial number on the box or on the board itself,  it can be determined if the modification has been done on the board.  The board's serial number is on the box end label.  The key is the last 5 digits of the serial number are the WorkWeek, Year, and M-site.

x x x x x x W W Y M M

Where:  ww = workweek;  y=year (1=1991, 2=1992); and MM= M-Site

IF THE M-SITE IS 07, then boards built during or after WorkWeek 20, 1992 have been modified.

IF THE M-SITE IS 13, then boards built during or after WorkWeek 25, 1992 have been modified.

IF THE M-SITE IS 12, then boards built during or after WorkWeek 21, 1992 have been modified.

Examples: 12345624213 has been modified.   12345620213 has NOT been modified.

Manufacturing is also reworking RMA'ed boards and boards that were in the warehouse when the modification started.  However, there is no easy way for them to mark the outside of the box to indicate the board inside has been modified.  They can, however, mark the board itself.  So, if a board was built before these dates, the customer must open the box and look for a "QAN" number on the back of the board.  This is a white label with the number 350032 printed on it.


Multimedia Bookshelf and NCR SCSI Card

If using the NCR 8250S PCI SCSI Card, Multimedia Bookshelf 1992 does not work properly.  The software causes the system to hang during setup.  Intel recommends using Bookshelf 1993 or  later version of the software.

Free Form Fields Not Updated

Problem

There is a problem that was introduced with version 5 of the BIOS in updating freeform fields.  If data is entered in a free form field, then you save and exit without leaving the field the CMOS information will not be updated.

Resolution

If you simply leave the field by using the arrow keys, so that a different field is highlighted before saving, the CMOS will be updated properly.  This oversight will be corrected if a future rev of the BIOS is written.


BIOS Reports Incorrect Processor

Problem

It has recently been noted that the i486SX2 type processors are reported as i486DX2 type processors by the BIOS.  This can be noted in both BIOS setup and certain programs that interrogate the BIOS for this information.

Resolution

This problem has existed on previous versions of the BIOS, and is due to the testing method.  This problem will not be compelling to rewrite the BIOS code but should be addressed in future versions of the BIOS, if any are required.

The BIOS reports type 2 PCI hardware configuration access cycle method,  but the method used by the Aries chip set is type 1.  This can present problems for operating systems, drivers, and software that tries to access this PCI configuration space.  This problem was initially noted with the NEXT operating system.  This operating system will not work properly on this platform with the current revision of the BIOS.

Resolution

There is no known work around.  This problem will be addressed with the next revision of the BIOS.


Can Not Install Secondary Hard Drive Controller

3/17/95

Problem

Due to legacy design holdovers the resources for the secondary hard drive are not released by the BIOS.  There is no method provided to release the secondary hard drive controller port 170h, or the secondary hard drive controller IRQ 15.  The BIOS presently assigns these resources to the on board controller for which no access method is provided.  This would be a consideration that must be accounted for when attempting to add an auxiliary controller.

Resolution

This problem can be bypassed by using a controller that does not require these resources (address 170h and IRQ15), such as a PCI type controller or a SCSI device and controller.  No other known work around exist at this juncture.  This issue is being considered at this time.   However, if the BIOS is rewritten at some future point this issue should be resolved.


Riser Card Signal overshoot

Problem:

A custom-designed add-in board used in one application has failed to run properly in the Classic/PCI.  Analysis shows that some address lines on the ISA connector on the PCI Riser card see as much as 2V overshoot on the rising edge of the signals.

Resolution:

Nearly all add-in cards include buffering devices on the signals connected to the ISA bus to protect the card's operation from expected overshoot. The overshoot seen on the Classic/PCI appears to be generated by impedance of the card and cross talk between signals.

The Classic/PCI and Premiere/PCI low profile systems use a common riser card and the design has been validated and compatibility tested with nearly 250 add-in devices. This issue has not been seen with any other add-in card.

Because of the potential for compromising the known compatibility with these hundreds of other devices, Intel feels it would not be prudent to implement a major design change for a single vendor.

General Product Information - CMOS Clears On System Reboot - Problem
Problem

If the system is powered down or rebooted between the conclusion of POST and the time when the floppy first begins to seek, the CMOS will be reset to default values.  This would be noted by a CMOS error on boot.


General Product Information - CMOS Clears On System Reboot - Resolution
Resolution

The original problem was due to a write window being opened and held open for an extended period during the boot process.  This problem has been corrected in version 5 of the BIOS.  The solution is to upgrade the system to version 5 of the BIOS.

Resolution


General Product Information - Printer Port Not Bidirectional - Problem
Problem

Certain hardware devices requiring a bidirectional parallel port were failing to operate correctly when the BIOS was set to "extended port" in the parallel port options.  If you chose this option in the BIOS it was not setting the parallel port to the correct type.  It was maintaining the compatible port type regardless of the option chosen in BIOS set up.


General Product Information - Printer Port Not Bidirectional - Resolution
Resolution

The version 5 BIOS addresses this issue by setting the port correctly to the type selected in configuration.  The solution is to update to revision 5 of the BIOS.

General Product Information - Can NOT Down Rev BIOS With Version 203 Board - Problem
Problem

If the last three digits of your PBA, TA, or AA is 203 your board contains the Cirrus GD5430 video controller chip.  This chip will not operate properly with the BIOS versions previous to revision 5 of the system BIOS.  Various problems occur when using this video controller with the video BIOS contained in earlier versions of the system BIOS including distortions of the icons in windows, no mouse pointer in windows, system hangs, etc.


General Product Information - Can NOT Down Rev BIOS With Version 203 Board - Resolution
Resolution

Any board containing -203 as the last digits in the PBA, AA, or TA must use version 5 of the system BIOS and video driver 1.22C.


PCI-PCI Bridges not Supported

11/8/94

Problem:

There is no support for PCI-PCI Bridges on the Classic Low Profile Desktop system.

Resolution:

Due to considerations in both BIOS and chip set used on the Classic Low Profile Desktop system base board there is no feasible means of implementing PCI-PCI bridging.  There are no current plans to address this mater in the future on this platform.  There will be support available on newer Pentium(R) platforms.

Technical Product Summary - Introduction
Introduction

The Classic/PCI Low Profile delivers excellent system performance using the Intel Aries PCI chip set, on-board PCI local bus graphics, PCI IDE, and up to two PCI expansion slots. The LPX motherboard supports the full range of Intel486™, IntelSX2™, IntelDX2™ and the new IntelDX4™ microprocessors at an affordable price point.

The IntelDX4 processor is the highest performing Intel486 processor, and is capable of operating at a 100 MHz internal clock with a 33 MHz input frequency. The IntelDX4 processor is driven by 3.3 volts (as opposed to 5 volts) and supports Intel's System Management Mode (SMM) power-management operation. The lower voltage allows the Classic/PCI Low Profile to qualify for the Environmental Protection Agency's Energy Star* computers program. An on-board voltage regulator circuit provides the required 3.3 volts to the CPU from the 12 volts provided by the power supply.

A Type 3 ZIF (Zero Insertion Force) OverDrive™ processor socket supports the full range of Intel486 processors and allows upgrades to higher performance in the future. Processor upgrades can be achieved simply by installing an OverDrive processor. Even larger performance gains can be achieved by installing a Pentium™ OverDrive processor. Additionally, the Classic/PCI Low Profile motherboard offers the following expansion features for performance-sensitive desktop applications:

•	Support for all i486, IntelDX2 and IntelDX4 processors

•	Auto-configuring PCI IDE with up to 6 MB/second throughput

•	Up to 256 KB of second level, write back cache

•	Two SIMM sockets for memory expansion to 64 MB

•	Riser card supports both PCI and ISA add-in cards

•	PCI Local bus graphics with 1 MB of video DRAM (expandable to 2 MB)

•	Plug and Play PCI and ISA

Mini LPX Form Factor

The Classic/PCI Low Profile motherboard is reduced in size from the full-length (13") LPX standards that are well established in the PC industry. The board complies with the standard for mounting locations, expansion slot placement and connector locations.


CPU

The Classic/PCI Low Profile motherboard has a wide price/performance range to meet a variety of customer needs. There are currently four i486 CPU configurations supported by the Classic/PCI Low Profile motherboard:

• 	an i486™SX running at 25 MHz;

• 	an IntelSX2 at 50 MHz;

• 	an IntelDX2 at 66 MHz; or

• 	an IntelDX4 at 100 MHz

The Classic/PCI Low Profile motherboard supports all of the functionality of the i486 processor. Common features of the CPU include backward compatibility with the 8086, 80286, and i386™ CPUs, burst mode bus cycles, and an on-chip 8 KB primary cache. The on-chip primary cache is 4-way set associative, uses a write-through policy, and can be disabled via software.

The i486 DX CPU contains an on-chip numeric coprocessor to increase the speed of floating-point operations. This coprocessor is backward code-compatible with the i387™DX and i387 SX math coprocessors and complies with ANSI/IEEE standard 754-1985. The i486 SX processor does not include the numeric coprocessor. The IntelDX2 and SX2 processors incorporate clock-doubling technology developed by Intel to significantly increase CPU performance without having to alter the system clock rate. The Intel DX4 processor operates at 3.3v for lower power consumption and offers a 3x internal clock multiplier for up to 100 MHz operation. The Intel DX4 processor also has an on-chip 16 KB primary cache for additional performance. All i486 processors shipped with the Classic/PCI Low Profile are SL-enhanced to minimize power consumption.


Processor Upgrades

The Classic/PCI Low Profile motherboard incorporates the 237-pin Type 3 Zero Insertion Force (ZIF) CPU socket for easy upgrades using an OverDrive Processor − including future OverDrive Processors based on the Pentium architecture. These upgrades will provide significantly higher CPU performance and numeric capability than the IntelDX2 and IntelDX4 processors.


Peripheral Component Interconnect (PCI) Chip Set

82425EX PCI System Controller (PSC)

82426EX ISA Bridge (IB)


82425EX PCI System Controller (PSC)

The 82425EX provides all control signals necessary to drive the DRAM and cache array and the PCI bus interface. The DRAM controller interfaces DRAM to the host bus, the PCI bus and the link bus and provides memory write posting to PCI for optimum CPU-to-PCI memory write performance. The cache controller supports both write-through and write-back policies and both interleaved or non-interleaved configurations. In addition, the PSC supports a PCI local bus IDE interface and supports desktop power management for SMM and Advanced Power Management (APM) BIOS.

Stepping Information:  A2 stepping components were the first PSC part shipped on this board.  They can be identified by the following marks on the component:

Vendor A	Vendor B
S82425EX Z897	S82425EX Z917


82426EX ISA Bridge (IB)

The 82426EX provides the bridge between the ISA bus and the PCI bus and host bus. It integrates a seven channel DMA controller, a 8254 timer/counter, two 82C59 interrupt controllers, power management support, and control logic for NMI generation, and decode for external BIOS, real-time clock and keyboard controller.

Stepping Information:  A1 stepping components were the first IB part shipped on this board.  They can be identified by the following marks on the component:

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

The Classic/PCI Low Profile motherboard provides two 72-pin SIMM sites for memory expansion. The sockets support 256K x 36 (1 MB), 512K x 36 (2 MB), 1M x 36 (4 MB), 2M x 36 (8 MB), 4M x 36 (16 MB), and 8M x 36 (32 MB) SIMMs. Either parity (x 36) or non-parity (x 32) 70 ns, fast-page SIMMs can be installed. If a non-parity SIMM is installed in either bank, the system automatically disables parity detection. If only parity SIMMs are installed, then parity generation/checking is provided for each byte. Minimum memory size is 1 MB with a maximum size of 64 MB using two 32 MB SIMMs.

The two sockets are arranged as Bank A and Bank B, with each socket representing a bank and providing a 32-bit wide data path and four parity bits if required. Banks A and B may have different types of memory installed. Bank A only, Bank B only, or both banks may be populated. There are no jumper settings required for the memory size, which is automatically detected by the system BIOS. Tin-lead SIMMs must be used when adding system memory.


Second Level Cache

In addition to the internal cache on the i486 CPU, the Classic/PCI Low Profile motherboard was designed with a second level cache using industry-standard SRAM. A direct-mapped, write-back cache controller is built into the Aries chip set. A total of ten DIP sockets (8 data SRAMs, 1 tag SRAM, & 1 dirty bit SRAM) are provided to support either 128 KB or 256 KB L2 cache configurations. The data and tag SRAMs must be 32K x 8, 15ns devices and the dirty bit must be a 16K x 1, 15ns device.


Intel 82091AA Super I/O Controller (AIP)

Control for the integrated serial ports, parallel port, and floppy drive interface is incorporated into a single component, the Intel 82091AA Advanced Integrated Peripheral (AIP). This component provides:

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

•	Multi-mode bi-directional parallel port

- Standard mode; IBM and Centronics compatible

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

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

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

Header pins located near the back of the board allow cabling to use these interfaces. The serial and parallel ports can be configured at a variety of I/O locations or disabled via the CMOS Setup utility. The floppy interface is configurable for 1.2 MB, 1.44 MB, and 2.88 MB densities for 3½" devices and 1.2 MB for 5¼" drives.


PCI Local Bus IDE

A high performance PCI local bus IDE interface is provided by the Intel Aries chip set (PSC) and is configured as the primary IDE interface. The PSC provides a timing bank consisting of programmable timing fields. This allows the PCI local bus IDE timing to be programmed for either 25 MHz or 33 MHz PCI frequencies, and for IDE modes 1, 2 and 3. DMA transfers are not supported across the IDE interface.

The system BIOS makes using IDE devices easier than ever with built-in support for four IDE translation modes: Standard Cylinder-Head-Sector (Standard CHS), Logical Block Addressing (LBA), and Extended CHS (ECHS). IDE auto-configuration allows the drives to be installed and recognized in CMOS setup without having to manually enter drive parameters. If the IDE auto-configure translation mode is selected in CMOS setup, the BIOS will issue an Identify Drive command and attempt to utilize LBA if it is supported by the drive. If LBA mode is not supported by the drive, the BIOS will attempt to use ECHS mode. If neither the LBA nor ECHS modes are supported by the drive, the BIOS will choose Standard CHS mode. Drive parameters can be entered manually for older drives that do not support the Identify Drive command.


Graphics Subsystem

The SVGA graphics subsystem, based upon the Cirrus Logic GD5430 PCI graphics controller, supports backward software compatibility with MDA, CGA, Hercules Graphics, EGA, and VGA graphics standards. The Classic/PCI Low Profile's standard configuration includes 1 MB of graphics DRAM, allowing resolutions up to 1024 x 768 x 256 colors, 1280 x 1024 x 16 colors, or 800 x 600 x 64K colors. The graphics memory can be increased to a total of 2 MB by adding two 256 KB x 16 fast page mode 70 ns DRAMs to the SOJ sockets on the system board. The upgrade will allow display resolutions of 1280 x 1024 x 256 colors or 1024 x 768 x 64K colors.

The Cirrus Logic GD5430 VESA DPMS-compliant video BIOS occupies 32 KB of Flash EEPROM space and is located at C0000H. The display ram is paged into 128 KB of RAM located between A0000H and BFFFFH.

Graphics Connectors

Graphics Drivers and Utilities


Graphics Connectors

A standard 15-pin analog VGA connector is provided on the system back panel. A VESA compliant 8514/A feature connector is located on the baseboard. The 8514/A interface typically is used as a VGA pass-through when an auxiliary video subsystem is installed in one of the expansion slots, such as the Intel Smart Video Recorder video capture board.


Graphics Drivers and Utilities

Graphics drivers and utilities for Windows 3.1 and OS/2 2.1 are shipped with the Classic/PCI Low Profile Desktop. These drivers come in a compressed form and are extracted by using an installation utility provided on the diskette. The graphics drivers for Windows 3.1 include a utility called WINMODE which allows the user to change the screen resolution, number of colors, and large or small fonts while in Windows. After the new options have been selected, the user can choose to immediately restart Windows or have the new options take effect the next time Windows is started. A utility called CLMODE.EXE is also included to allow selection of video modes from a DOS environment.

Graphics drivers for common MS-DOS software applications such as AutoCAD*, AutoDesk*, AutoShade*, AutoSketch*, GEM/3*, Lotus* 123, Microsoft* Word, WordPerfect*, WordStar*, and Ventura Publisher* are not included on the driver diskette but can be downloaded from the Intel Applications Support BBS. Drivers for SCO* and Interactive UNIX* should be obtained from the respective UNIX vendor.


Keyboard and Mouse Interface

An Intel 8242 surface mount microcontroller contains the Phoenix compatible keyboard/mouse controller code. The PS/2-style keyboard and mouse connectors are located on the back panel side of the motherboard. The 5V line on 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.

The 8242 microcontroller code supports Power-On/Reset (POR), network, and keyboard password protection. The POR password is set via the Setup program. The keyboard controller also provides for the following keystroke combinations:

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

•	<CTRL><ALT><+> and <CTRL><ALT><->: Turbo mode selection. <CTRL><ALT><-> sets the system for de-turbo mode (emulation of an 8 MHz 80286 CPU using wait states) and <CTRL><ALT><+> sets the system for turbo mode (normal operation at 33 MHz). Changing the Turbo mode may be prohibited by an operating system or application software.

•	<CTRL><ALT><x>: Sleep hot-key, where <x> is chosen by the user. This sequence generates a System Management Interrupt (SMI) and, if enabled in Setup, causes the system to enter power down mode by reducing power to the CPU, IDE hard drive(s), and monitor.


Real Time Clock, CMOS RAM and Battery

The Real Time Clock (RTC) function is provided by a Dallas DS12887 device. The DS12887 is accurate to within ±13 minutes/year and requires no external support because the lithium battery, quartz, and support circuitry are integrated into the DS12887. The RTC time and date can be set via the BIOS Setup program.

The DS12887 contains 128 bytes of batterybacked CMOS RAM of which 14 bytes are for the RTC and control registers and 114 bytes are for general purpose RAM. CMOS RAM is totally nonvolatile with over 10 years of operation in the absence of power. All of the CMOS RAM is reserved for BIOS use only. The CMOS RAM can be set to specific values or cleared to the system default values using the BIOS Setup program. The CMOS RAM values can also be cleared to the system defaults by using a hardware jumper. Refer to Appendix B for jumper configuration details and to Appendix D for more information regarding BIOS Setup.


Riser Card Connector

The Classic/PCI Low Profile motherboard contains one custom riser card connector. This connector is used to support a riser card that can contain up to five horizontal ISA bus expansion slots or up to two PCI expansion slots or a combination of the two types. The expansion cards are oriented parallel to the motherboard, rather than perpendicular. This parallel orientation makes possible the low profile chassis outline. The connector is identical to those used in an EISA system: ISA signals are directed to the standard ISA positions, and PCI signals are available via the deep finger method. The location of the riser connector fully conforms to the LPX specification for mechanical fit.

Technical Product Summary - Riser Card Connector - PCI 3.3 Volt Capabilities
PCI 3.3 Volt Capabilities

To maintain strict compliance with the PCI specification, the motherboard provides a connector which can be used to route 3.3 volt power to the PCI slots. The connector may be used with a separate 3.3 volt power supply or with a custom designed voltage converter. (Note that the on-board 3.3 volt regulator provides power for the CPU, not the PCI slots.)


System BIOS

The Classic/PCI Low Profile motherboard uses the American Megatrends Incorporated (AMI) i486 ROM BIOS stored in Flash EEPROM which can be upgraded using a floppy disk-based program. BIOS upgrades can be downloaded from the Intel Applications BBS. In addition to the AMIBIOS, the Flash EEPROM also contains the CMOS Setup utility, Power-On Self Tests (POST), update recovery code, and the PCI auto-configuration utility. The motherboard supports system BIOS shadowing, allowing the BIOS to execute from 32-bit on-board write-protected DRAM.

The BIOS displays a sign-on message during POST identifying the type of BIOS and a revision code. Initial production units will display a revision code of 01.AZ0. As BIOS updates occur, the revision number will increase to 02.AZ0, 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.

System Address		FLASH Memory Area
F0000H	FFFFFH	64 KB Main BIOS
EE000H	EFFFFH	8 KB Boot Block (Not FLASH erasable)
ED000H	EDFFFH	4 KB Reserved
E8000H	ECFFFH	20 KB System BIOS Reserved
E0000H	E7FFFH	32KB VGA BIOS space
The 128KB 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, switching 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. See details on recovering the BIOS following a catastrophic failure.


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 from the Intel Applications BBS.

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 disk file to ensure the system has the correct BIOS version.

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


Setup Utility

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

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

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

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

•	ISA interrupts IRQ9, IRQ10 and IRQ11 may be assigned to add-in ISA adapters, thereby informing the PCI configuration utility which interrupts not to use.

•	Selection of Advanced Power Management options such as IDE hard drive and monitor power down, and a sleep "hot-key" combination that can be used to activate power down mode.

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


PCI Auto-configuration Capability

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


Plug And Play ISA

Plug and Play ISA BIOS extensions are fully supported for ease of installation of ISA add-in cards. System configuration data is stored in the on-board FLASH device. The Plug and Play ISA function fully complies with version 1.1 of the specification.


Advanced Power Management

The system BIOS fully supports the Advanced Power Management (APM) interface specification that provides hardware-independent power management capabilities to operating systems and other applications that also support APM. Setup options allow specification of a "sleep" hot-key combination and a system inactivity timeout value that will cause the BIOS to issue a System Management Interrupt (SMI) to the i486 SL-Enhanced processor and place the system into a "sleep" state. Additional setup options allow the IDE hard drive(s) and/or VESA DPMS-compliant monitor to also be power managed when an SMI occurs. These power management features allow the Classic/PCI Low Profile to fully meet the EPA Energy Star program requirements for energy efficient computers.


Security features

BIOS Password

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

If the password is forgotten, it can be cleared by turning off the system and setting the  Clear Password (J1F3) jumper to the CLEAR position (pins 2-3), cycling the system power on and off again, and restoring the jumper to its default position (pins 1-2).

Setup Enable Jumper

A baseboard jumper controls access to the BIOS Setup utility. By setting this jumper to the disable position, the user is prevented from accessing the Setup utility during the Power-On Self Test or at any other time.

Flash Write-Protect Jumper

A baseboard jumper controls the ability to update the Flash BIOS via the Flash Upgrade utility. If this jumper is set to the write-disable position, the PCI auto-configuration and ISA Plug and Play utilities will report system errors if the system configuration is altered in any manner.

Floppy Boot disable

The setup option "System Boot Up Sequence" in the Advanced CMOS Setup can be set to prevent the system from being able to boot from a floppy disk.


Back Panel Connectors

The back panel provides external access to PS/2-style keyboard and mouse connectors, two 9-pin serial ports, a 25-pin parallel port and a standard 15-pin VGA connector which are all integrated on the Classic/PCI Low Profile motherboard.


Labels

The Classic/PCI Low Profile motherboard has three numbers printed on labels to identify each board assembly.

Serial number	A unique number assigned to each manufactured board.
PBA number	A number used to track engineering changes made to the assembled baseboard.  This number is in the form of 123456-789
AA number	A number used to distinguish between processor and memory options installed onto the assembled baseboard. This number also tracks engineering changes and is in the form 123456-789.


Location designators

All devices and connectors on the Classic/PCI Low Profile motherboard are identified on the silk-screen by their location on the board. The board is mapped out in a grid pattern defined by numbers along one axis and by letters on the other axis. The first letter designates components with a U, connectors and jumpers with a J, resistors with an R, and capacitors with a C. For example, the i486 processor socket is identified as U3B1; meaning it is the first component identified at the intersection of 3 and B.

Allows recovery if the system FLASH update process results in corrupted EPROM

1-2 = Normal Boot (default)

2-3 = Recovery Boot

Flash Write Enable − J1G3

Allows reprogramming of Flash EPROM to be enabled or disabled

1-2 = Flash Write Enabled (default)

2-3 = Flash Write Protected

CMOS Setup Enable − J1G2

Allows access to CMOS Setup Utility to be disabled.

1-2 = Access to Setup allowed (default)

2-3 = Access to Setup prevented

2-3 = Clear CMOS to default settings

Clear Password  − J1F3

Allows system password to be cleared.

1-2 = Password Enabled (default)

2-3 = Clear Password

CPU Clock Speed -- J1F1, J1F2

There are two jumpers to select 25/33 MHz processor clocks. Both jumpers must have the same configuration for the CPU clock speed to be properly set. The default setting is determined by the processor shipped on the motherboard. Motherboards shipped without processors will be configured for a 33 MHz clock (1-2).

1-2 = 33 MHz

2-3 = 25 MHz

CPU Voltage (3.3v or 5v) − J1A1,J1A2,J2A2,J2A3

These four jumpers need to be moved to allow the use of the IntelDX4 microprocessor which operates at 3.3 volts. When all of the jumpers are moved into the 3.3 volt position (1-2) the on-board voltage regulator converts 5v to 3.3v for the IntelDX4 processor. This supplies 3.3v only to the processor socket. Default position is 2-3 for 5 volt operation.

1-2 = 3.3 volt

2-3 = 5 volt (default)

WARNING: Do NOT move these jumpers while the power is on! The CPU could be damaged.

Reserved − J4A1

This jumper is reserved and should not be altered.

Pentium Overdrive Processor Cache Enable -- J5A1

This jumper normally is set to position 1-2. When installing a Pentium OverDrive processor, this jumper must be changed to 2-3 to properly set up the L1 cache for write-back mode.

1-2 = non Pentium OverDrive processors (default)

2-3 = Pentium OverDrive processor cache enabled

CPU Type (SL/non-SL) − J5A2

This jumper is set to position 1-2 for non SL-enhanced processors and set to 2-3 for SL-enhanced processors. Note: All motherboards and systems shipped with processors have SL-enhanced processors installed.

1-2 = non SL-enhanced processors

2-3 = SL-enhanced processors (default)

CPU Type (SX/non-SX) − J5A3

This jumper is set to position 2-3 for i486 SX processors and set to 1-2 for all other Intel processors. Note: The default setting is determined by the processor shipped. Motherboards shipped without processors will be configured for non SX processors (1-2).

1-2 = non SX processors (default)

2-3 = i486 SX processors

Cache Size − J5A4, J5A5

Two jumpers to select cache options of 128 KB/256 KB. Both jumpers must have the same configuration for the cache to be properly set. If secondary (L2) cache is not installed, these jumper settings have no effect.

1-2 = 256 KB (default)

2-3 = 128 KB

System Level Features

A slimline case gives the Classic/PCI Low Profile a sleek look, while four peripheral bays and five expansion slots offer the expandability required for traditional PC applications. A 145 watt power supply ensures that the system can support installation of the maximum number of peripherals and add-in cards. The Classic/PCI Low Profile 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" bay. Both 5¼" bays and one of the 3½" bays are accessible from the front panel. The final 3½" hard drive bay is internal. The two 5¼" bays also can accommodate a single 5¼" full-height drive.


Expansion Slots/Riser Card

The Classic/PCI Low Profile supports up to three ISA and two PCI horizontal bus expansion slots via the LPX riser card. Two of the ISA and one of the PCI slots are located on the side of the riser card farthest from the power supply with one ISA and one PCI slot located on the side nearest the power supply (see back panel diagram). The two expansion slots nearest the power supply are limited to use by half-length add-in cards due to the position of the 3½" peripheral carrier. The lowest ISA expansion slot on the side farthest from the power supply is also limited to use by a half-length add-in card due to the height of the CPU and voltage regulator heat sink.  See the Funtional Consideration regarding use of full-length slots in the bottom ISA slot.


Technical Product Summary - System Level Features - PCI 3.3 Volt Capabilities
PCI 3.3 Volt Capabilities

To maintain strict compliance with the PCI specification, the motherboard provides a connector which can be used to route 3.3 volt power to the PCI slots. The connector may be used with a separate 3.3 volt power supply or with a custom designed voltage converter. (Note that the on-board 3.3 volt regulator provides power for the CPU, not the PCI slots.)  Also see the Functional Consideration regarding this feature.


Alternate ISA Riser Card, ISARISER10

This riser card is for customers who need more ISA slots on one of Intel's PCI-based low profile platforms. The card supports five ISA slots and can be installed in place of the riser that ships standard with the platform (offering 2 PCI and 3 ISA slots).

This solution is ideal for customers who want to move from the Intel486 processor-based Classic-S and Classic R-Plus products to the newest generation of low profile products, including those based on the Pentium processor. This ISA riser card can be installed in the Intel486 processor-based Classic/PCI LP, the 60/66 MHz Pentium processor-based Premiere/PCI LC, or the 90 MHz Pentium processor-based Premiere/PCI LX.

Equipment OEMs and VARs will find that the five-slot ISA riser card eases their migration from proprietary ISA cards to PCI-based solutions. The product can be integrated into the system at the Intel integration center or an Authorized Distributor VAD center.

Features	Benefits
Five ISA expansion slots	Permits continued use of ISA cards
ISA Plug and Play compliant	Simplified integration and configuration
Available for the latest Intel OPSD platforms	Ensures continued support of ISA add-in cards while migrating to new technology

Technical Product Summary - BIOS Release 5 Setup - Introduction
Introduction

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

Main Menu

Advanced Menu

Security Menu

Exit Menu

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

 Explanations and comments here.


Command Screen Navigation

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

F1	Help

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

ESC	Back

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

Exit Discarding Changes

Press Enter to Continue

Press ESC to Abort

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

Enter	Select

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

Previous Item

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

Next Item

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

Select Menu

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

F5	Setup Defaults

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

Load Setup Defaults?

Press Enter to Continue

Press ESC to Abort

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

F6	Previous Values

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

Discard Changes?

Press Enter to Continue

Press ESC to Abort

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

F10	Save & Exit

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

Exit Saving Changes?

Press Enter to Continue

Press ESC to Abort

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


Menu Navigation

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


Main Menu

System Date

Month-Day-Year

The System Date field specifies the current date.

System Time

Hour:Minute:Second

The System Time  field specifies the current time.

Floppy A: Type

Floppy B: Type

Disabled  -- Default for Floppy B:

360 Kb, 5.25 "

1.2 Mb, 5.25"

720Kb, 3.5"

1.44 Mb, 3.5"  -- Default for Floppy A:

2.88 Mb, 3.5"

The Floppy A: Type and Floppy B: Type fields specify the physical size and maximum supported media size of the floppy drives attached to the floppy interface.

Hard Disk C:

Hard Disk D:

Hard Disk E:

Hard Disk F:

Identification string returned from drive

Not Installed

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

Language

English (US)

..

..

The Language field controls the language of the text strings used in Setup and the BIOS.  Any installed language will appear as an option in its own language (for example, German will appear as Deutch).  Only installed languages will appear as options.

Boot Options

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

Video Mode

The Video Mode  field is informative only.

Mouse

The Mouse  field is informative only.  The Classic/PCI Expandable Desktop will never show this field.  The Classic/PCI Low Profile will display this field if the mouse is installed.  In general, if the system does not support a PS/2 style mouse, or if it does and the mouse is not installed, this field will not be displayed.

Base Memory

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

Extended Memory

The Extended Memory field is informative only. Amount of system memory above 1 Megabyte

Hard Disk Sub-Menu

Hard Disk Type

Auto Configured -- default

User Definable

Number of Cylinders

Number of Heads

Number of Sectors

If Hard Disk Type = Auto Configured

Then parameters reported by drive

If Hard Disk Type = User Definable

Then parameters entered by user

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

Maximum Capacity

Value calculated from Cylinder, Head, and Sector info above

Initialization Timeout

Disabled	-- default for drives D:,E:,F:

5 Seconds

10 Seconds 	-- default for drive C:

31 Seconds

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

IDE Translation Mode

Standard CHS -- default

Logical Block

Extended CHS

Auto Detected

The IDE Translation Mode parameter controls the way in which the BIOS interacts with the drive in terms of drive geometry.  Proper choice is dependent upon the drive's size, capabilities, and the operating system (OS) used. Standard CHS is the translation mode that has been in use for years.  Its use limits IDE capacity to a maximum of 528 Megabytes regardless of the size of the drive.

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

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

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

Different operating systems have different abilities regarding IDE Translation Modes:

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

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

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

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

Multiple Sector Setting

Disabled

4 Sectors/Block

8 Sectors/Block

Auto Detected -- default

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

Fast Programmed I/O Modes

Disabled

Auto Detected -- default

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

Disk Drive Assignments

Drive letters will be assigned to physical drives as follows:

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

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

Drive 1
Primary Partition	C:
Secondary Partition	F:
Drive 2
Primary Partition	D:
Secondary Partition	G:
Tertiary Partition	H:
Drive 3
Primary Partition	E:
Secondary Partition	I:
Boot Options Sub-Menu

Boot Sequence

C: First, Then A:

A: First, Then C: -- default

C: Only

A: Only

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

System Cache

Disabled

Enabled -- default

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

Boot Speed

Turbo -- default

De-turbo

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

Num Lock

Off -- default

On

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

Setup Prompt

Disabled

Enabled -- default

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

Hard Disk Pre-Delay

Disabled

1 Second

2 Seconds

3 Seconds -- default

4 Seconds

5 Seconds

6 Seconds

7 Seconds

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

Typematic Rate Programming

Default -- default

Override

The parameter controls whether default or user configurable values are used for Typematic Rate Delay and Typematic Rate (see below).  If Default is chosen then Typematic Rate Delay is set to 500 msec and Typematic Rate is set to 6.  If Override is chosen the following two screens appear allowing the user to customize these values.

Typematic Rate Delay

250 msec -- default

500 msec

750 msec

1000 msec

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

Typematic Rate

6 char/sec -- default

8 char/sec

10 char/sec

12 char/sec

15 char/sec

20 char/sec

24 char/sec

30 char/sec

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


Advanced Menu

The Peripheral Configuration, Advanced Chipset Configuration, Power Management, and Plug and Play Configuration fields are used to enter sub-menus where these areas are configured.  Press Enter to access.

Peripheral Configuration Sub-Menu

Configuration Mode

Auto -- default

Manual

The Configuration Mode fields controls whether  on board resources are manually or automatically set up.  When set to Auto, on board  system peripherals (IDE drives, Floppy Drive, Serial Ports, Parallel Port) are automatically configured during power up.  When set to Manual, system peripherals must be explicitly configured.  The following 5 fields (IDE Interface to Parallel Port Address) are only user accessible when Configuration Mode is set to Manual.

IDE Interface

Enabled -- default

Disabled

Floppy Interface

Enabled -- default

Disabled

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

Serial Port 1 Address

COM4, 2E8h

Serial Port 2 Address

Disabled

COM1, 3F8h

COM2, 2F8h -- default

COM3, 3E8h

COM4, 2E8h

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

Parallel Port Address

Disabled

LPT3, 3BCh

LPT1, 378h -- default

LPT2, 278h

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

Parallel Port Mode

Compatible -- default

Extended

ECP

When set to Compatible, the parallel port will be set up in a mode compatible with the original AT parallel port which is a unidirectional  port.      When set to Extended the parallel port will be set up for a fast bidirectional mode compatible with the IEEE 1284 specifications for an EPP parallel Port.               When set to ECP the port will be set to the most advanced mode allowed by the chipset, which is also compatible to the IEEE 1284 specification for an ECP parallel port.

Serial Port 1 IRQ

Interrupt Used

Serial Port 2 IRQ

Interrupt Used

Parallel Port IRQ

Interrupt Used

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

Advanced Chipset Configuration Sub-Menu

Byte Merging

Enabled

Disabled -- default

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

ISA LFB Size

Disabled -- default

1 MB

3 MB

7 MB

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

ISA LFB Base Address

Dependent upon ISA LFB Size

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

Power Management Configuration Sub-Menu

Advanced Power Management

Enabled

Disabled -- default

The Advanced Power Management  field enables or disables Advanced Power Management (APM) support in the BIOS.  If set to enabled the BIOS will work with APM aware Operating Systems to manage the power consumed by the CPU,  IDE drives, and graphics cards.  If set to Enabled then the other fields in the Power Management Configuration Sub-Menu are displayed.

IDE Drive Power Down

Enabled

Disabled -- default

The IDE Drive Power Down field controls whether or not a spin down command will be issued to the IDE drives when the system goes into low power mode.

 VESA Video Power Down

Disabled -- default

Standby

Suspend

Sleep

The VESA Video Power Down field controls the VESA power management command issued to the graphics card when the system goes into low power mode.  The proper setting is dependent upon the VESA mode(s) supported by your  graphics card.

Inactivity Timer (Minutes)

0 to 255

0 -- default

The Inactivity Timer (Minutes) field controls the number  of  minutes that the system will detect no user activity before going into low power mode.

Hot Key

User  definable

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, typically about a minute before the system actually goes into power managed mode,  however the speaker will issue 2 descending tones.

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 in sequence, 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, whether the screen is active or inactive at the time the password is entered (see Set User Password  field in Security Menu).   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 1 minute (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 sequence Input accepted when password typed
Both Hot Keys Enabled	System Secure Immediately System powers down 1 minute (can include screen blanking if enabled) LEDs sequence Input accepted when password typed Powers up when any key/mouse activity is detected	System Secure Immediately  System powers down 1   minute (can include screen blanking if enabled) LEDs sequence Input accepted when password typed Powers up when any key/mouse activity is detected
Plug and Play Configuration Sub-Menu

Configuration Mode

Use Setup Utility -- default

Use ICU

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

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

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

ISA Shared Memory Size

Disabled -- default

16 KB

32 KB

48 KB

64 KB

96 KB

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

This field should be set to Disabled unless an ISA card is used which communicates with the CPU through a block of shared memory located in the upper memory area.  If set to a value other than Disabled  the ISA Shared Memory Base Address field will appear below.  Note that if a value of  96 KB is chosen, then the ISA Shared Memory Base Address field can only be set to C8000h or below.

* These options will not be visible if consumed by on-board resources (IRQ4 Serial Port 1, IRQ3 Serial Port 2, IRQ7 Parallel Port 1, IRQ5 Parallel Port 2).

Note: If auto configuration mode is selected in the periphrial sub menu, IRQ 5 and IRQ 7 will not be shownin this menu.  This is due to the fact that the plug and play standard requires that resources be flexible.  If you wish to choose specific IRQs use the manual configuration mode in the periphrial sub menu, and choose the IRQs you wish for the com and parallel port IRQs.  The remaining open IRQs will show up on this menu.

The IRQ 3 - IRQ 15 fields are used to indicate whether individual interrupts are used by ISA legacy cards.  If not used, then they should be set to Available.  If used they should be set to Used By ISA Card.  Note: All but one can be set to Used By ISA Card.  One must remain available for PCI cards which use interrupts to function.


Security Menu

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

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

1.	System Date

2.	System Time

3.	User Password

4.	Security Hot Key

User Password is

Disabled -- default

Enabled

Administrative Password is

Disabled -- default

Enabled

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

Set User Password

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

Enter New Password_______

Confirm New Password_______

Press Enter or TAB to Accept

Press ESC to Abort

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

Enter Current Password_______

Enter New Password_______

Confirm New Password_______

Press Enter or TAB to Accept

Press ESC to Abort

Set Administrative Password

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

Enter New Password_______

Confirm New Password_______

Press Enter or TAB to Accept

Press ESC to Abort

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

Enter Current Password_______

Enter New Password_______

Confirm New Password_______

Press Enter or TAB to Accept

Press ESC to Abort

Unattended Start

Disabled -- default

Enabled

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

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

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

Security Hot Key (CTRL-ALT-)

Alpha-Numeric Key

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


Exit Menu

Exit Saving Changes

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

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

Exit Saving Changes?

Press Enter to Continue

Press ESC to Abort

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

Discard Changes?

Press Enter to Continue

Press ESC to Abort

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


AMIBIOS 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 prevent the system from continuing the boot process and are communicated through a series of audible beeps. Other errors are displayed in the following format:

ERROR Message Line 1

ERROR Message Line 2

Press <F1> to RESUME

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

BIOS Recovery

The Classic/PCI Low Profile 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 can be run from a hard drive or a network drive, but no memory managers can be installed during upgrades.

The latest upgrade utility and BIOS code are available for download from the Intel Applications Support BBS.

Using The Upgrade Utility

Recovery mode


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.xx 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.

Once the new BIOS is installed, Enter Setup and press <F5> to set the BIOS to its defaults.  This ensures the new CMOS Map is cleared of the old values and reset to the new requirements.  Now you are able to modify the BIOS settings as needed.


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 Recovery Boot Enable jumper (J1G4) to the recovery mode position (2-3).

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 Recovery Boot Enable jumper back to the default position (1-2).

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

8.	Continue with the original upgrade.

Reliability Data

For calculation of baseboard MTBF, Intel uses supplier data for digital ICs and belcore calculations for all other components.  For system level MTBF calculation, Intel uses the result of the base board calculation and combines this data with supplier data for other sub-assemblies.  Floppy duty cycle is 5%, the other parts of the calculation are assumed 100% duty cycle.

The predicted Mean-Time-Between-Failure (MTBF) data is calculated to be the following:

Classic/PCI Low Profile system	26,963 hours @ 35° C.
LPX motherboard (w/4 MB and CPU)	105,100 hours @ 50° C.
LPX riser card	380,100 hours @ 50° C.
Power supply (Astec SA145-3430)	80,160 hours @ 50° C
Floppy drive (Teac FD-235HF)	81,000 hours @ 50° C.
The auxiliary fan is considered a wear-out item with a rated lifetime of 20,500 hours @ 50° C.

The demonstrated MTBF of the 486LP8D266 is 27,250.21 hours at 40°C, 80% LCL.
