Microprocessor

The motherboard supports Intel Pentium II processors with MMX technology and secondary (L2) cache.
The Pentium II processor is packaged in a Single Edge Contact (S.E.C.) cartridge that mounts in the Slot 1 processor connector on the motherboard.

Main Memory (DRAM)

The motherboard supports up to 256 MB of DRAM. DRAM is implemented through four 72-pin SIMM sockets. The motherboard contains four SIMM sockets. To add memory to the motherboard, see the motherboard's main memory map, see
Memory error checking and correction is supported with parity or ECC SIMMs. Parity or ECC SIMMs are automatically detected; however, the user must enter Setup to configure SIMMs for either parity or ECC operation. Parity memory will detect single-bit errors. ECC memory will detect multi-bit errors and correct single­bit errors. Errors may be generated by a defective memory module, mixing different speed memory modules, or by DMA or memory conflicts.

Product Description

BIOS Features

The BIOS, from American Megatrends, Inc. (AMI), provides ISA and PCI compatibility. The BIOS is contained in a Flash memory device soldered to the motherboard. The BIOS provides the POST, the Setup program, a PCI and IDE auto-configuration utility, and BIOS recovery code.

PCI Auto-configuration

The PCI auto-configuration utility works in conjunction with the Setup program to support using PCI add-in cards in the computer. When you turn on the power after installing a PCI card, the BIOS automatically configures interrupts, DMA channels, and I/O space. Since PCI add-in cards use the same interrupt resources as ISA add-in cards, you must specify the interrupts used by ISA cards in the Setup program. The PCI auto-configuration program complies with version 2.1 of the PCI BIOS specification.

IDE Auto-configuration

The motherboard automatically detects installed IDE devices and configures them for operation.

ISA Plug and Play Capability

The motherboard provides auto-configuration of Plug and Play ISA cards and resource management for legacy (non Plug and Play) ISA cards when used with the ISA Configuration Utility (ICU) or a Plug and Play compatible operating system like Windows 95. To obtain the ICU, contact your computer supplier.

Security Features

The BIOS provides a password option that you can enable through the Setup program (refer to
A26361-D1005-Z120-2-7619
Using the BIOS Setup Program
).

Product Description

BIOS Upgrades

Because the BIOS is stored in a Flash memory device, you can upgrade the BIOS without having to disassemble the computer. The upgrade can be done with a utility stored on a diskette or hard disk or run over a network. To upgrade the BIOS, refer to Upgrade the BIOS.

Expansion Slots

The motherboard has two dedicated 16-bit ISA/AT-compatible and three dedicated PCI-compatible expansion slots. Another expansion slot is a combination slot that can be used for either a PCI or an ISA card. This allows you to install a maximum of six add-in cards.

Real-time Clock and CMOS RAM

The I/O controller provides a real-time clock and CMOS RAM. You can set the time for the clock and the CMOS values by using the Setup program described in Using the BIOS SETUP Program.

Battery

A battery on the motherboard keeps the clock and values in CMOS RAM current when your computer is turned off. To replace the battery, see Installing and configuring motherboard options.

Speaker

An optional speaker is mounted on the motherboard. The speaker provides audible error code information (beep codes) during the POST if the BIOS cannot use the video interface. For beep code descriptions, see Error and Information Messages.

Page 15
Product Description
The board also has a connector for an optional offboard speaker. To
✏
install an offboard speaker, remove the jumper that enables the onboard speaker (refer to
Technical Reference
).

Fan Connectors

The motherboard has connectors for two fans. For the locations and pinouts of the fan connectors, see
Technical Reference
.

USB Interface Support

The USB ports permit the direct connection of two USB peripherals without an external hub. If more devices are required, an external hub can be connected to either of the built-in ports. The motherboard supports the standard universal host controller interface (UHCI) and uses standard software drivers that are UHCI­compatible.

Configuration Mode
In the delivery status, this setting is set to Use BIOS Setup . When the default values are being set (Load Setup Defaults), this value must then be reset to Use BIOS Setup.
Sets how the BIOS gets information about non-Plug and Play ISA add-in cards. The options are:
• Use PnP OS (default)
•
Use BIOS Setup (factory setting)
If Use BIOS Setup is selected, specify the IRQ for each non-Plug and Play ISA add-in card you install on the motherboard (see page 32, IRQ 3, 4, 5, 7, 9, 10, 11, 14, 15).
If Use PnP OS is selected, the BIOS uses run-time software to prevent conflicts between Plug and Play and non-Plug and Play add-in cards. If Use PnP OS is selected, PnP OS is the only option visible in the subscreen.

If this field is set to Disabled, the ISA Shared Memory Base Address field (described below) will not appear.
This field should be enabled only when you are using a non-Plug and Play ISA add-in card (legacy card) that requires non-ROM memory space. For example, video capture cards that have video buffer memory.
By default, allocation of upper memory is as follows: memory from C0000h­C7FFFh is automatically shadowed. (This memory range is typically reserved for video BIOS.) Memory from C8000h-DFFFFh is initially unshadowed. The BIOS scans this range for any ISA add-in cards that may be present and notes their location and size. The BIOS will then automatically configure the PCI and Plug and Play devices, shadowing the ROM requirements (other than video) into the area above E0000h until that area is full. It will then assign additional PCI and Plug and Play add-in cards to the area between C8000h and DFFFFh. If an ISA legacy card has non-ROM memory requirements, the autoconfigure routine may write into an area that is needed by the ISA add-in card. The ISA Shared Memory Size parameter signifies to the autoconfigure routine that this block of memory is reserved and should not be shadowed.
Shadowing copies a block of memory from an add-in card's ROM to the same address in computer DRAM memory. This improves computer performance.
A26361-D1005-Z120-2-7619

Page 40
Using the BIOS Setup Program
ISA Shared Memory Base Address
Sets the base address for the ISA shared memory. The options are:
•
C8000h (default)
• CC000h
• D0000h
• D4000h
• D8000h
• DC000h
This setting could affect the ISA Shared Memory Size field. The value entered in the ISA Shared Memory Size field cannot extend to the E0000h address. For example, if a size of 64 KB were selected, options D4000h, D8000h, and DC000h would not appear.
If the ISA Shared Memory Size field is disabled, this field will not appear.
IRQ 3, 4, 5, 7, 9, 10, 11, 14, 15
Sets the status of the IRQ. The options are:
•
Available (default)
• Used By ISA Card
The PCI auto-configuration code looks here to see if these IRQs are available for PCI add-in cards. If an IRQ is available, the PCI auto-configuration code can assign the IRQ to be used by the computer. If your computer has an ISA add-in card, select Used By ISA Card for one of these IRQs.
IRQs 5, 9, 10, and 11 are the default user available IRQs. Depending on the configuration of your computer, other IRQs could be listed. If you have disabled the parallel port or either of the serial ports, more IRQs will be available. Refer to Technical Reference ("Motherboard Resources", "Interrupts") for information on reserved and available IRQs. If an ICU diskette was supplied with your computer, you can use the ICU (ISA Configuration Utility) utility to check how the interrupts are assigned. Boot your computer with the ICU diskette inserted and follow the instructions on the screen.

WARNINGs
!
The procedures in this chapter assume familiarity with the general terminology
ssociated with personal computers and with the safety practices and
egulatory compliance required for using and modifying electronic equipment.
isconnect the computer from its power source and from any telecom-
munications links, networks, or modems before doing any of the procedures
escribed in this chapter. Failure to disconnect power, telecom-munications links, networks, or modems before you open the computer or do any procedures can result in personal injury or equipment damage. Some circuitry on the motherboard may continue to operate even though the front panel power button is off.
Electrostatic discharge (ESD) can damage components. Do the procedures described in this chapter only at an ESD workstation. If such a station is not available, you can provide some ESD protection by wearing an antistatic wrist strap and attaching it to a metal part of the computer chassis.

Jumpers

Figure 3 shows the location of the jumper block on the motherboard. The jumpers have been set correctly at the factory. Normally, the only time you will have to change a jumper is if you need to do one of the following:
Clear the user or administrator password.
Reset CMOS RAM to the default values.
Disable or enable access to the Setup program.
Configure the motherboard for a different processor speed.
As shown in Figure 3, a jumper is a small plastic-encased conductor that slips over jumper pins. To change a jumper setting, remove the jumper from the pins and slide it onto the new pins to obtain the desired setting. You can use a pair of fine needle nose pliers to remove and install jumpers.
To avoid bending or breaking pins, use caution when removing or installing a jumper.

How to Install Memory

The motherboard has four 72-pin, tin-lead SIMM sockets that support from 8 MB to 256 MB of memory. The sockets are arranged as banks 0 and 1 (Figure 6). Two sockets make up one bank.
When adding memory, follow these guidelines:
• When adding SIMMs, use only tin-lead,
72-pin, 50 or 60 ns EDO DRAM. Faster devices will not improve system performance.
• When you install SIMMs, you must completely fill at least one bank; that is,
you must install SIMMs in both sockets of the bank.
• The computer automatically detects the installed memory, so it doesn't matter
which bank is used, as long as both sockets in the bank are filled. Because of limited space on the motherboard, it might be easier to install SIMMs in bank 0 first.
• Both SIMMs in one bank must be the same size. For example, don't install a 4
MB SIMM in one socket of bank 0 and an 8 MB SIMM in the second socket of bank 0. You may, however, use different size SIMMs in different banks.

The motherboard supports parity (x36) or non-parity (x32) SIMMs. Error checking and correction is supported with parity and ECC SIMMs. There is no error checking and correction with non-parity SIMMs.

To install SIMMs, do the following:
Observe the precautions in "Before You Begin” (see page 41).
Turn off all peripheral devices connected to the computer. Turn off the
computer. Remove the computer cover.
Holding the SIMM only by the edges, remove it from its antistatic package.
Position the SIMM at about a 45° angle relative to the motherboard. Make
sure the small notch in the middle of the bottom edge of the SIMM aligns with the notch in the SIMM socket.
Insert the bottom edge of the SIMM into the SIMM socket and make sure it is
seated firmly. When the SIMM seats correctly, hold it at each end and gently push the top
edge towards the retaining clips of the connector until the SIMM snaps into place (Figure 7). If the SIMM does not install correctly, gently spread the retaining clips just enough so that you can pull away the top edge of the SIMM and try again.
Reinstall and reconnect any parts you removed or disconnected to gain
access to the SIMM sockets. Replace the computer cover.

How to Replace the Battery

When your computer is turned off, a lithium battery keeps the time-of-day clock and the values in CMOS RAM current. Figure 8 shows the location of the battery.
The battery should last about seven years. When the battery begins to die, it loses voltage; when the voltage drops below a certain level, the Setup program settings stored in CMOS RAM (for example, the date and time) might not be accurate. If the battery dies, replace it with an equivalent battery.
If your local ordinances permit, you may dispose of individual batteries as normal trash. Do not expose batteries to excessive heat or fire. Keep all batteries away from children.
Danger of explosion if the battery is incorrectly replaced. Replace only with the same or equivalent type recommended by the equipment

Upgrading the BIOS

This chapter explains how to use the BIOS upgrade utility and how to recover the BIOS if an upgrade fails.

Record the Current BIOS Settings

Boot the computer and press <F1> when you see the message:
Press <F1> Key if you want to run SETUP
Do not skip step 2. You will need these settings to configure your computer at the end of the procedure.
Write down the current settings in the BIOS Setup program (see
BIOS Setup Program
).

How to Upgrade the BIOS

To upgrade the BIOS, you will need the Flash upgrade utility, the files containing the new BIOS, and the files for BIOS recovery.
To obtain these files, contact your computer supplier.
Using the
The following steps explain how to upgrade the BIOS.

Make a Copy of the Current BIOS

Insert the bootable floppy disk with the upgrade files into drive A of the
computer you want to upgrade. Boot the computer. The BIOS Upgrade Utility appears.
To go to the Main menu, press <Enter>.
Select Save Flash Memory to a File.
Select Save System BIOS.

Upgrading the BIOS
Type the path and file name (with the .bio extension) for the saved BIOS. For example:
A:\oldbios.bio
Press <Enter>.
If there is not enough space on the disk, use another pre-formatted floppy disk to save the old BIOS.
Type a description of this BIOS in the Image Title area. For example:
Old BIOS as of 10 Oct 96
Press <Enter>.
To copy the current BIOS to the floppy disk, press <Enter>.
When the copy is complete, the Main menu displays.
If you used a different floppy disk to save the old BIOS, remove it. Insert the BIOS upgrade floppy disk in drive A.

Upgrade the BIOS

Boot the computer. The BIOS Upgrade Utility appears.
Select Update Flash Memory From a File.
Select Update System BIOS. Press <Enter>.
Use the arrow keys to select the correct .bio file. Press <Enter>.
When the utility asks for confirmation that you want to load the new Flash into memory, select Continue with Programming. Press <Enter>.
When the utility displays the message upgrade is complete, remove the floppy disk. Press <Enter>.
As the computer boots, check the BIOS identifier (version number) to make sure the upgrade was successful.
To enter the Setup program, press <F1> when you see the message:
Press <F1> Key if you want to run SETUP
For proper operation you must load the Setup program defaults. To load the defaults, press <F5>.
To accept the defaults, press <Enter>.

Upgrading the BIOS
Set the options in the Setup program to the settings that you wrote down
before the BIOS upgrade. To save the settings, press <F10>.
To accept the settings, press <Enter>.
Turn off the computer and reboot.

How to Recover the BIOS If an Upgrade Fails

It is unlikely that anything will interrupt the BIOS upgrade; however, if an interruption occurs, the BIOS could be damaged. The following steps explain how to recover the BIOS if an upgrade fails.
Because of the small amount of code available in the non-erasable boot block area, there is no video support. You will not see anything on the screen during the procedure. Monitor the procedure by listening to the speaker and looking at the floppy drive LED.
Turn off the computer and disconnect the AC power cord from the computer.
Remove the computer cover. See
Installing and configuring motherboard options
(Figure 3) for the location of
the BIOS recovery jumper. On jumper block J9C1-A, move the jumper from pins 5-6 to pins 4-5 as shown
below.

Listen to the speaker.
− Two beeps and the end of activity in drive A indicate successful BIOS recovery.
− A series of continuous beeps indicates failed BIOS recovery.
If recovery fails, return to step 1 and repeat the recovery process.
If recovery is successful, turn off the computer and disconnect the AC power cord from the computer. Remove the computer cover and continue with the following steps.
On jumper block J9C1-A, move the jumper back to pins 5-6 as shown below.
