2 Introduction
Unpacking the Mainboard
The mainboard package contains:
¥ The 82440LX Mainboard
¥ One CD (including Manuals/Drivers/Utilities)
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.

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 momentarily shorting this jumper; then
open the jumper to retain new settings.

Memory Configuration
The mainboard supports four banks of 168-pin 3.3V EDO/SDRM
Unbuffered DIMM. The mainboard supports from 8 to 512 Mbytes
with no other restrictions on memory configurations. You can install
DRAM in any combination without having to rely on a memory
configuration table. Memory configuration is thus ÒTable-FreeÓ in any
bank.
8 Hardware Setup
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 ECP + EPP
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.
JP1 — 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.
