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 andconfiguring 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 InformationMessages.

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.
Features of the USB include:
Support for self-identifying, hot-pluggable peripherals
•
Automatic device configuration
•
Support for isochronous and asynchronous transfers over the same set of
•
wires
Support for up to 127 physical devices

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

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

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.

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.
A26361-D1005-Z120-2-7619

Page 58
Installing and Configuring Motherboard Options
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
!
manufacturer. Discard used batteries according to manufacturer's
instructions.

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.
