Unpacking the Mainboard & Static
Electricity Precautions
This Mainboard package contains the following items:
1. This Mainboard and the Device Driver
2. The Slot1 holder
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.
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 the mainboard into the system
chassis, you may find it convenient to first configure
the mainboardÕs hardware. This chapter describes how
to set jumpers and install memory modules, and where
to attach components.
6 Chapter 2
CPU Installation
This mainboard supports Intel Pentium¨ II CPU using
a Single Edge Contact (SEC) slot. Make sure that you
have the following items (which should be included in
the package) before doing any installation. All parts
are labeled here with item numbers which will be
refered to in the Installation Procedures section. Item 1
and 2 together are the retention mechanism, please
refer to following procedures to complete your CPU
installation.
1) 4 screws:
2) 1 retention clip:
Hardware Configuration 7
Installation Procedures
Follow the following steps in order to install your Intel
Pentium¨ II properly.
Step 1:
Make sure that the mainboard is set the same direction
as the following drawing before doing any installation.
8 Chapter 2
Step 2:
There are 2 sets of small holes along Slot 1 of your
mother board: two on the top and two on the bottom.
Snap the retention clip (2) right into those 2 sets of holes
PW1
Item 2
Slot 1
If the retention clip is installed incorrectly, you will not
be able to insert the retention clip into the CPU and in
this situation you might need to rotate the retention clip
by 180¡.
Step 3:
Find the hole in each corner of the retention clip then
insert the 4 screws from the top of the motherboard.
Holes for screws
Hardware Configuration 9
Step 4:
And then simply push the screws downward to secure
the the retention clip.
Push in to secure.
Step 5:
Flatten the two latches on the side of CPU. Insert the
CPU into the retention clip. Lock the two latches to
secure the CPU.

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.

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: Hold down the <End> key then power on to reboot the
system when installing newer BIOS into this
mainboard .

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:
