Unpacking the Mainboard & StaticElectricity 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 orinstalling the mainboard.
1. Do not remove the mainboard from its originalpackage until you are ready to install it.
2. Frequently ground yourself to discharge any staticelectric charge that may build up in your bodywhile working on installation and/orconfiguration. For example, you may groundyourself by grasping an unpainted portion of thesystemÕs metal chassis.
3. Remove the mainboard from its anti-staticpackaging and place it on a grounded surface,component side up.
4. Handle the mainboard by its edges or by themounting bracket to avoid touching itscomponents.
5. Check the mainboard for damage. If any integratedcircuit appears loose, press carefully to seat itfirmly in its socket.
6. Do not apply power if the mainboard appearsdamaged. If there is damage to the board contactyour dealer immediately.
Chapter 2Hardware Configuration
Before you install the mainboard into the systemchassis, you may find it convenient to first configurethe mainboardÕs hardware. This chapter describes howto set jumpers and install memory modules, and whereto attach components.

CPU Installation
This mainboard supports Intel Pentium¨ II CPU usinga Single Edge Contact (SEC) slot. Make sure that youhave the following items (which should be included inthe package) before doing any installation. All partsare labeled here with item numbers which will berefered to in the Installation Procedures section. Item 1and 2 together are the retention mechanism, pleaserefer to following procedures to complete your CPUinstallation.
1) 4 screws:
2) 1 retention clip:
Hardware Configuration 7
Installation Procedures
Follow the following steps in order to install your IntelPentium¨ II properly.
Step 1:
Make sure that the mainboard is set the same directionas the following drawing before doing any installation.
8 Chapter 2
Step 2:
There are 2 sets of small holes along Slot 1 of yourmother board: two on the top and two on the bottom.Snap the retention clip (2) right into those 2 sets of holes
Slot 1
Item 2
PW2
If the retention clip is installed incorrectly, you will notbe able to insert the retention clip into the CPU and inthis situation you might need to rotate the retention clipby 180¡.
Step 3:
Find the hole in each corner of the retention clip theninsert 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 securethe the retention clip.
Push in to secure.
Step 5:
Flatten the two latches on the side of CPU. Insert theCPU into the retention clip. Lock the two latches tosecure the CPU.

Chapter 4BIOS Setup
This chapter explains how to configure the mainboardÕsBIOS setup program. The setup program providedwith the mainboard is the BIOS from AMI.
After you have configured the mainboard and haveassembled the components, turn on the computer andrun the software setup to ensure that the systeminformation is correct.
The software setup of the system board is achievedthrough Basic Input-Output System (BIOS)programming. You use the BIOS setup program to tellthe operating system what type of devices areconnected to your system board.
The system setup is also called CMOS setup. Normally,you need to run system setup if either the hardware isnot identical with information contained in the CMOSRAM, or if the CMOS RAM has lost power.
Note: Hold down the <End> key then power on to reboot thesystem when installing newer BIOS into thismainboard .
20 Chapter 4
Entering BIOS Setup
To enter the BIOS Setup program:
1. Turn on or reboot the system. A screen appearswith a series of diagnostic checks.
2. When ÒHit <DEL> if you want to run SETUPÓappears, press the <DEL> key to enter the BIOSsetup program. The following screen appears:
