Static Electricity Precautions
Static electricity can easily damage your mainboard.Following procedures can help you to protect yourmainboard from electrostatic discharge:
1. Keep the mainboard and other system componentsin their antistatic packaging until you are ready toinstall them.
2. Ground yourself before removing any systemcomponent from its protective anti-staticpackaging. A grounded surface within easy reachis the expansion slot covers at the rear of the systemcase or any other unpainted portion of the systemchassis.
4 Chapter 1
3. Frequently ground yourself to discharge any staticelectric charge that may build up in your bodywhile working on installation and/orconfiguration.
4. Handle the mainboard by its edges or by themounting bracket to avoid touching itscomponents.
Unpacking the Mainboard
This Mainboard package contains the following items:
1. The i440LX Mainboard
2. This UserÕs Guide
3. Cables: 1 slot1 supporter and holder;1 floppy ribbon cable;1 IDE ribbon cable
4. The Device Driver for i440LX
Note: Do not remove the mainboard from its originalpackage until you are ready to install it.
The mainboard is easily damaged by static electricity.Follow the precautions below while unpacking orinstalling the mainboard.
1. Before handling the mainboard, ground yourself bygrasping an unpainted portion of the systemÕsmetal chassis.
2. Remove the mainboard from its anti-staticpackaging and place it on a grounded surface,component side up.
Introduction 5
3. Check the mainboard for damage. If any integratedcircuit appears loose, press carefully to seat itfirmly in its socket.
Do not apply power if the mainboard appearsdamaged. If there is damage to the board contact yourdealer immediately.

Memory Installation
The mainboard lets you add up to 384MB of systemmemory through DIMM sockets on the board. Eachbank consists of three 168-pin DIMM sockets aredivided into three banks: Bank 0, Bank 1, and Bank 2.The mainboard supports the following memoryconfigurations.
Bank Memory ModuleBank 0DIMM1(168-pin DIMM)
4MB, 8MB, 16MB, 32MB, 64MB, 128MB
Bank 1DIMM2(168-pin DIMM)
4MB, 8MB, 16MB, 32MB, 64MB, 128MB
Bank 2DIMM3(168-pin DIMM)
4MB, 8MB, 16MB, 32MB, 64MB, 128MB
Total System Memory = Bank 0 + Bank 1 + Bank 2
Notes: 1. The speed of all DIMM modules have to be faster than 70ns.2. Use 2 DRAM types: Extend Data Out (EDO), or
Synchronous DRAM (SDRAM) for DIMM socket.
Chapter 3BIOS 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: When installing newer BIOS into this mainboard, JP3must be set to clear CMOS position for a moment thenset back to Normal Mode, or hold down the <End> keythen power on to reboot the system.

Security
User
This item lets you configure the system passwordwhich is required every time when the system boots upor an attempt is made to enter the Setup program. Thepassword cannot be longer than six characters.
Note: Keep a safe record of the new password. If you forgetor lose the password, the only way to access the systemis to discharge CMOS memory using Jumper JP3.
