Introduction 5
Unpacking the Mainboard & Static
Electricity Precautions
This Mainboard package contains the following items:
1. The Mainboard
2. The Device Driver for this mainboard
3. This UserÕs Guide
4. Sound & Game ribbon cables/bracket
5. ATX Form Card (optional)
The mainboard is easily damaged by static electricity.
Follow the precautions below while unpacking or
installing the mainboard.
1. Do not remove the mainboard from its original
package until you are ready to install it.
2. Frequently ground yourself to discharge any static
electric charge that may build up in your body
while working on installation and/or
configuration. For example, you may ground
yourself by grasping an unpainted portion of the
systemÕs metal chassis.
3. Remove the mainboard from its anti-static
packaging and place it on a grounded surface,
component side up.
4. Handle the mainboard by its edges or by the
mounting bracket to avoid touching its
components.
Page 8
6 Chapter 1
5. Check the mainboard for damage. If any integrated
circuit appears loose, press carefully to seat it
firmly in its socket.
6. Do not apply power if the mainboard appears
damaged. If there is damage to the board contact
your dealer immediately.

Hardware Configuration 15
Memory Installation
The mainboard lets you add up to 384MB of system
memory through SIMM and DIMM sockets on the
board. Four SIMM sockets on the mainboard are
divided into two banks: Bank 0 and Bank 1. Each bank
consists of two 72-pin SIMM modules and three 168-pin
DIMM sockets are divided into three banks: Bank 0,
Bank 1, and Bank 2. The mainboard supports the
following memory configurations.
Bank Memory Module
Bank 0
SIMM1 & SIMM2
DIMM1
2 x 4MB/8MB/16MB/32MB/64MB
or
4MB, 8MB, 16MB, 32MB, 64MB, 128MB

Bank 2
DIMM3 4MB, 8MB, 16MB, 32MB, 64MB, 128MB
Total System Memory = Bank 0 + Bank 1 + Bank 2
Notes: 1. The following two types of DRAM module can not be used at
the same time: SIMM 1 & 2 and DIMM1 or SIMM3 & 4
and DIMM2.
2. Use 2 DRAM types: FPM/EDO faster than 70ns for SIMM
socket.
3. Use 3 DRAM types: FPM/EDO/SDRAM faster than 70ns
for DIMM socket.

ATX Functions & Connectors 17
The functions and connectors described below work
with the ATX power supply.
Software Power-Off
Follow the steps below to use the ÒSoftware Power-Off
ControlÓ function in Windows 95 with ATX power
supply.
1. Click the START button on the Windows 95 task
bar.
2. Select Shut Down The Computer to turn off the
computer. The message ÒIt is now safe to turn off
your computer.Ó will not be shown when using this
function.
Modem Ring Power-On
While in Soft-off/Suspend state, if an external modem
ring-up signal occurs, the system wakes up and can be
remotely accessed. Make sure that the Ring Resume
From Soft Off option is set to Enabled in the BIOS setup
section (Refer to the Power Management section in
Chapter 4.)
Alarm Wake Up
If you want to autoboot the system at a certain time, set
the function of RTC Alarm time properly and the
function of RTC Alarm Resume From Soft Off option in
the BIOS Setup section will be set to Enabled.

J2 (21, 22) (PWRBT) – ATX Power Button and Suspend
Switch Connector
Attach the ATX Power Button or Suspend Switch cable
to this connector.
In the AT power system, this connector will act as a
suspend switch; and in the ATX power system, this
connector will be not only an ATX power button but a
Suspend switch as well. Details are described below:
When the system is off, push the power button to turn
the system on. When the system is on, push the power
button rapidly to switch the system to the Suspend
mode, and, by pushing and holding the button for
more than 4 seconds, it will turn the system completely
off. When the system is in the Suspend mode, push the
power button rapidly to turn the system on.

Chapter 4
BIOS Setup
This chapter explains how to configure the mainboardÕs
BIOS setup program. The setup program provided
with the mainboard is the BIOS from AMI.
After you have configured the mainboard and have
assembled the components, turn on the computer and
run the software setup to ensure that the system
information is correct.
The software setup of the system board is achieved
through Basic Input-Output System (BIOS)
programming. You use the BIOS setup program to tell
the operating system what type of devices are
connected to your system board.
The system setup is also called CMOS setup. Normally,
you need to run system setup if either the hardware is
not identical with information contained in the CMOS
RAM, or if the CMOS RAM has lost power.
Note: When installing newer BIOS into this mainboard, you
must clear CMOS for a moment then set back to
Normal Mode, or hold down the <End> key then
power on to reboot the system.

OffBoard PCI IDE
Card
This option specifies if an offboard PCI IDE
controller adapter card is installed in the
computer. You must specify the PCI
expansion slot on the motherboard where the
offboard PCI IDE controller is installed. If an
offboard PCI IDE controller is used, the
onboard IDE controller is automatically
disabled. If an offboard PCI IDE controller
adapter card is installed in the computer, you
must also set the Offboard PCI IDE Primary
IRQ and Offboard PCI IDE Secondary IRQ
options.
OffBoard PCI IDE
Primary IRQ;
OffBoard PCI IDE
Secondary IRQ
These options specify the PCI interrupt used
by the Primary (or secondary) IDE channel on
the offboard PCI IDE controller.

Security
User
This item lets you configure the system password
which is required every time when the system boots up
or an attempt is made to enter the Setup program. The
password cannot be longer than six characters.
Note: Keep a safe record of the new password. If you forget
or lose the password, the only way to access the system
is to discharge CMOS memory using Jumper JP1.
Anti-Virus
This item protects the boot sectors and partitions table
of your hard disk against accidental modifications.
Any attempt to write to boot sectors and partitions will
cause the system to halt and you need to use a bootable
none virus floppy disk to reboot the system and then

run the virus checking program to make sure that your
system is ok.
The default setting is ÒDisabled.Ó This setting is
recommended due to the conflicts within new
operating systems.
