2 Introduction

Unpacking the Mainboard

The mainboard package contains:

¥ The 82440BX Mainboard

¥ One CD (including Manuals/Drivers/Utilities)

¥ One Quick Installation Guide

Notice that if the board comes with a driver disc and a manual, then

the Quick Installation Guide and the CD-ROM will not be included

in the package.

Note: Do not unpack the mainboard until you are ready to install it.

Follow the precautions below while unpacking the mainboard.

1. Before handling the mainboard, ground yourself by grasping an

unpainted portion of the systemÕs metal chassis.

2. Remove the mainboard from its anti-static packaging and place it on

a grounded surface, component side up.

3. Check the mainboard for damage. If any chip appears loose, press

carefully to seat it firmly in its socket.

Do not apply power if the mainboard appears damaged. If there is

damage to the board contact your dealer immediately.

Electrostatic Discharge Precautions

Make sure you ground yourself before handling the mainboard or other

system components. Electrostatic discharge can easily damage the

components. Note that you must take special precaution when handling

the mainboard in dry or air-conditioned environments.

Take these precautions to protect your equipment from electrostatic

discharge:

¥ Do not remove the anti-static packaging until you are ready to install

the mainboard and other system components.

¥ Ground yourself before removing any system component from its

protective anti-static packaging. To ground yourself grasp the

expansion slot covers or other unpainted portions of the computer

chassis.

¥ Frequently ground yourself while working, or use a grounding strap.

¥ Handle the mainboard by the edges and avoid touching its

components.

Important: Make sure the system is well ventilated to prevent

overheating and ensure system stability.

2 Hardware Setup

This chapter explains how to configure the mainboardÕs hardware. After

you install the mainboard, you can set jumpers, install memory on the

mainboard, and make case connections. Refer to this chapter whenever

you upgrade or reconfigure your system.

CAUTION: Turn off power to the mainboard, system chassis, and

peripheral devices before performing any work on the

mainboard or system.

Jumpers

Clear the CMOS memory by shorting this jumper to 2Ð3; then set the

jumper back to 1Ð2 retain new settings.

CPU Type Configuration

This mainboard is designed so that it is not necessary to use any jumpers

to set the CPU frequency and multipliers onboard. Instead of using

6 Hardware Setup

jumpers, the settings for the CPU frequency are set through the BIOS

Setup which allows you to use any type of CPU from the Pentium II

familyÕs 233 ~ 550 range.

In order to change the CPU type, you need to enter the BIOS by pressing

the <Delete> key during boot-up and then select the ÒChipset Features

SetupÓ menu. There is an item called ÒCPU SpeedÓ under this setup

section and it allows you to set the frequency according to the speed of

the Pentium II CPU that you have, which should be clearly indicated on

the outer cover. The choices of settings are 133, 233, 266, 300, 333, 350,

400, 450, 500, and 550 MHz. Notice that the fastest CPU available was

400MHz at the time of this board was released, therefore we can

guarantee proper functioning only up to 400 MHz. The 133 and 200

MHz settings are used as default and as a ÒsafeÓ frequency, which means

that the board can be boot-up at any time even if the BIOS settings are

erased or reset, there is however no Pentium II CPU of those frequencies.

The 133MHz value is used for CPUs with a 66MHz Bus Clock, and the

200 MHz value is used for CPUs with a 100MHz Bus Clock. The BIOS

will automatically detect the Bus Clock of your CPU.

If the frequency is set too high, the CPU will not be able to function

properly and the board will not boot up. By pressing the <Insert> key a

few times while turning on the computer, the frequency will be set back

to the default value and you will be able to enter the BIOS Setup to

correct the CPU frequency value.

Memory Configuration

The mainboard supports four banks of 168-pin 3.3V SDRM Unbuffered

DIMM. The mainboard supports from 8 to 384 Mbytes with no other

restrictions on memory configurations. Use 12ns or faster DIMM

modules for 66MHz and use 8ns modules for 100MHz host bus CPUs.

DIMM Configuration

1 1st

2 2nd 1st

3 3rd 2nd 1st

Note: It is very important that you install DIMM modules as outlined in

the table above in order to preserve the signal integrity on

100MHz host bus systems.

Hardware Setup 7

Multi I/O Port Addresses

Default settings for multi-I/O port addresses are shown in the table

below.

Port I/O Address IRQ Status

LPT1* 378H 7 SPP

COM1 3F8H 4

COM2 2F8H 3

* If default I/O port addresses conflict with other I/O cards (e.g. sound

cards or I/O cards), you must adjust one of the I/O addresses to avoid

address conflict. (You can adjust these I/O addresses from the BIOS.

Note: Some sound cards have a default IRQ setting for IRQ7, which may

conflict with printing functions. If this occurs do not use sound

card functions at the same time you print.

Connectors

Attach the mainboard to case devices, or an external battery, via

connectors on the mainboard. Refer to Figure 1-1 for connector locations

and connector pin positions.

P1 — ATX Power Supply Connectors

The motherboard provides an ATX power supply connector. It is a

twenty-pin male header connector. Plug the connector from the power

directly onto the board connector while making sure the pin1 is in its

position.
