Introduction 5
Unpacking the Mainboard & Static
Electricity Precautions
This Mainboard package contains the following items:
1. This Mainboard and a Device Driver
2. This UserÕs Guide and AT cable set
3. Sound & Game ribbon cables/bracket and
SPDIF/IN cable
4. ATX Form Card
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.
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.
Chapter 2
Hardware Configuration
Before you install this mainboard into the system
chassis, you may find it convenient to first configure

Total System Memory = Bank 0 + Bank 1 + Bank 2
Notes: 1. The speed of SDRAM DIMM modules have to be faster than
12ns (ÒÐ12Ó parts). When 100MHz clock speed is being
used, then the speed of SDRAM DIMM should meet the
PC100 SDRAM specification (8ns or ÒÐ8Ó SDRAM at
least).
2. The speed of EDO/FPM DRAM have to be faster than 70ns,
but it is not recommended for the performance purpose of the
system.

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.
16 Chapter 3
JP11 (21, 22) (PWB) – 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 need to clear CMOS for a
moment then set back to Normal Mode or hold
down the <End> key then power on to reboot
the system.
18 Chapter 3
Entering BIOS Setup
To enter the BIOS Setup program:
1. Turn on or reboot the system. A screen appears
with a series of diagnostic checks.
2. When ÒHit <DEL> if you want to run SETUPÓ
appears, press the <DEL> key to enter the BIOS
setup program. The following screen appears:
