2 Introduction

Unpacking the Mainboard

The mainboard package contains: ¥ The 82430TX Mainboard ¥ This UserÕs Guide ¥ One IDE Bus Master driver diskette

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

JP2: Smart Detect CPU Voltage Function Auto/Manual

Jumper

This jumper is reserved for few old non-Intel CPUs which can not be detected correctly. If you run into problems while detecting the voltage of old non-Intel CPUs, remove this jumper to correct it.

JP37: DIMM Voltage Select Jumper

Most of DIMMs in the consumer market is still 3.3V and this jumper is reserved only for upgrading purpose in the near feature. If you have 5V SIMM or DIMM which matches the existing 3.3V DIMM socket on this mainboard, than you need to set this jumper to 5V before installing the SIMM or DIMM.

DIMM Voltage JP37

3.3V (default)

Caution: Do not change this jumper to 5V setting unless you are sure

that your DIMMs are 5V. The wrong setting may cause the system malfunction.

CPU Type Configuration

This section shows you how to configure your CPU step by step. Note that you need to check the CPU voltage before installation. This board supports the Intel P54C/P55C/MMX, Cyrix 6x86/6x86L/6x86MX, and AMD 5K86/K5/K6 CPUs. With the MMX technology supported, you should be able to use MMX CPUs and configure these CPUs as normal dual voltage CPUs.

❑ Step 2: CPU Single/Dual Voltage Setting

There are two kinds of CPU input voltages due to various designs of CPUsÑsingle voltage and dual voltage. Set your CPU according to the type that you have.

For Intel P54C/P55C single and dual voltage series CPUs, there is no need to adjust any jumper for CPU voltag due to the Smart Detect CPU Voltage function.

Single Voltage CPU Setting

Signal voltage CPUs use the same voltage for VIO and VCore and has been used traditionally. The CPUs which fall into this category are Intel P54C series, AMD-K5-PRxxxBx, AMD-K5-PRxxxCx, AMD-K5PRxxxFx, and Cyrix 6x86. Refer to the following figures to set these CPUsÕ voltage:

Memory Configuration

The mainboard supports two banks of 72-pin SIMM modules and three strips of 168-pin/3.3V Unbuffered DIMM modules. The mainboard

requires SIMM of at least 70ns access time.

The mainboard supports from 4 to 256 Mbytes with no other restrictions on memory configurations. You must install two strips of SIMM modules to complete a bank.

On TX chipset motherboards, there is a memory limitation when the system has more than 2 DIMM sockets. The limitations are :

1. Maximum memory size is 256MB total for all RAM socket.

2. DIMM 1 won’t support 64MB or 128MB DIMMs with 64Mbit SDRAM

cells.

3. If DIMM 2 and/or DIMM3 has 64MB or 128MB DIMM’s with 64Mbit
