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 systems 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.

Hardware Setup

This chapter explains how to configure the mainboards 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

JP5: CMOS Clear Jumper
Clear the CMOS memory by setting this jumper to 23, then set the jumper back to 12 to retain the new settings. CMOS Setting JP5 Retain CMOS data (default) Clear CMOS data

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 familys 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 Chipset Features Setup menu. There is an item called CPU Speed 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, and 333 MHz. The 133 MHz setting is used as default and as a safe 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.
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.

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 systems 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.

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 three banks of 168-pin 3.3V EDO/SDRAM Unbuffered DIMM. The mainboard supports from 8 to 384 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 Table-Free in any bank. The SIMM bank can not be used together with the DIMM banks. The SIMM bank takes two EDO SIMM modules that have to be of the same size. FTP modules can not be used. The SIMM bank supports up to a maximum of 128MB of memory (2x 64KB modules).

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.

Change the password as follows: 1. Choose USER PASSWORD in the Main Menu and press <Enter>. The following message appears: Enter Password: 2. Enter a password and press <Enter>. (If you do not wish to use the password function, you can just press <Enter> and a Password disabled message appears. ) 3. After you enter your password, the following message appears prompting you to confirm the new password: Confirm Password: 4. Re-enter your password and then Press <ESC> to exit to the Main Menu. 5. You are not allowed to change any setting in CMOS SETUP UTILITY except change users 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.
