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.

* There is no 133MHz in the Pentium II CPU family. 133MHz setting
is used as default and as a ÒsafeÓ frequency to allow the board to
boot-up at any time when the BIOS settings are erased or reset. Refer
to the ÒCPU Type ConfigurationÓ section of Chapter 2.
Important: Make sure the system is well ventilated to prevent
overheating and ensure system stability.
Page 9
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.

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
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 233-333 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 Frequency Pentium IIÓ
under this setup section and it allows you to set the frequency according
tot the speed of the Pentium II CPU that you have, which should be
clearly indicated on the case. The choices of settings are 133, 233, 266,
300, and 333 MHz. The 133 MHz setting is used as default and as a
ÒsafeÓ frequency which means the board can be boot-up at any time even
if the BIOS settings are erased or reset, however, there is no Pentium II
CPU of that frequency.
Page 10
6 Hardware Setup
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, 133MHz, 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 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.
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.

Slot 1 Installation Guide
This board provides a non-boxed 686 (PII) CPU retention set to secure
the CPU to the board. Follow the steps below to secure this type of CPU
on to your motherboard. These steps are the same for both Slot 1 CPUs.
In case you use only one CPU you will have to use the termination card
that came with the board, we advise you to insert your CPU into slot #1
and insert the termination card into slot #2.
Termination Card
Step 1:
Find the ATX PW and the Slot 1 on the board and set the board in the
direction as follows before doing any installation.

Turbo Mode (75Mhz) Enabled: Your Pentium II CPU will run
on a 75Mhz busclock which will
increase the speed of your
system. This busclock falls
without the specifications of
INTEL, however, so no
guarantees of proper functioning
are made. In addition you have
to use high quality Add-On
cards and memory Modules
when running the system at a
busclock of 75Mhz to avoid
problems.
Disabled: Your system will run on the
INTEL specified busclock of
66Mhz.
CPU Frequency Select the frequency of your Pentium II
CPU from the following: 233, 266, 300, or

These two items both set the BIOS settings back to their default values.
The difference between the two is that BIOS Defaults loads the most
conservative values, meaning that it is best to load the BIOS defaults
whenever you are experiencing problems; on the other hand, Setup
Defaults setting are optimized for speed and are usually the best settings
to load.
Default settings can be loaded through choosing one of two items after
which a message appears:
ÒLoad SETUP Defaults (Y/N)? NÓ

ÒLoad BIOS Defaults (Y/N)?NÓ
Pressing <Enter> key will not load the defaults, you need to press Y and

Supervisor Password
The main difference between the User and Supervisor Password is that
the Supervisor Password allows access to all BIOS settings, however on
Page 38
34 BIOS Setup
the other hand, the User Password offers only restricted access which
means that the Chipset Features Setup, Power Management Setup, and
PnP/PCI Configuration are all restricted for a user that entering the BIOS
Setup by using only a User Password. The User Password is set to
Disabled by default and only after defining a supervisor password the
User Password can be defined. The following procedure shows you how
to set or change a supervisor password:
1. Choose ÒSUPERVISOR PASSWORDÓ from the Main Menu and
press <Enter>. If you have already defined a password, type in the
password first in order to proceed. The following message appears:
ÒEnter Password:Ó
2. Enter a password and press <Enter>.
(If you do not wish to use the password function, you can just press
<Enter> and a ÒPassword disabledÓ message appears. )
3. After you enter your password, the following message appears
prompting you to confirm the new password:
ÒConfirm Password:Ó
4. Re-enter your password and then Press <ESC> to exit to the Main
Menu.
The User Password option is available only after setting the Supervisor
password and the procedure of setting the User Password is done the
same way as the Supervisor Password.
Important: If you forget or lose the password, the only way to access
the system is to set jumper JP5 to clear the CMOS RAM.
All setup information is lost and you must run the BIOS
setup program again.

IDE HDD Auto Detection
Selecting this item will make the system automatically scan for all the
