2 Introduction

Unpacking the Mainboard

The mainboard package contains:

¥ The EQ82C663X Mainboard

¥ One CD (including UserÕs Manual, Drivers, and 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

This mainboard uses different colors of jumper caps to identify different

functions of the jumpers:

6 Hardware Setup

JP22: CPU Burst Mode Jumper

Due to different designs, there are two kinds of CPU burst modes:

Interleave Burst and Linear Burst. Select the correct mode according to

the CPU you are using.

CPU Burst Mode JP22

Interleave

(for P54C/P55C and AMD

K5/K6 CPU)

Linear

(for Cyrix 6x86/L/MX CPU)

When using a Cyrix series of CPUs, follow the below procedures after

select the burst mode:

1. Press<Delete> key to enter the BIOS setup menu during the boot-up,

2. Select ÒChipset Features SetupÓ,

3. Set the ÒLinear BurstÓ to ÒEnabledÓ,

4. Press <Esc> to go back to the main menu and choose ÒSave & Exit

SetupÓ to reboot your computer.

JP4: Smart Detect CPU Voltage Auto/Manual Jumper

For P54C/P55C and Cyrix 6x86/L CPUs, this board automatically

detects and adjusts the CPU voltage to the proper voltage. JP4 is

reserved for a few older non-Intel CPUs which can not be detect

correctly. If you run into problems while detecting the voltage of older

CPUs, remove the jumper cap to correct it.

Hardware Setup 7

JP2, JP6: Power Supply Selection Jumpers

These two jumpers let you select either the AT or the ATX power

supply. Use only one power supply at a time on this mainboard.

JP37: DIMM Voltage Jumper

There are two kinds of DIMM voltages in the marketÑ3.3V and 5VÑ

and most of SDRAM DIMMS are 3.3V. Choose the correct voltage

according to the DIMM that you are using.

DIMM Voltage JP37 Setting

3.3V

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.

2. Use 8ns SDRAM or faster (for PC100) when using a host bus

frequency of 100MHz. However, this limitation does not

apply to EDO modules.

3. When the SDRAM module is slower than 8ns, JP9 and JP10

must be set to AGP frequency.

CPU Type Configuration

SW1 and JP30 are the only switchs/jumpers that you need to set for your

CPU on this mainboard. Make sure that you know the type of CPU that

you are installing and refer to the proper settings which are listed below.

If you have a higher frequency CPU then the one listed below, see the

ÒQuick Installation GuideÓ for more SW1 information.

SW1: Frequency Setting. Some newer CPUs may not be included in

this section, please refer to the Appendix for more information.

JP30: Voltage Setting. There are two kinds of CPU voltages

currently on the marketÑSingle and Dual. The CPUs which

fall under the single voltage category are: P54C, AMD-K5, and

Cyrix 6x86. The CPUs which fall under the dual voltage

category are: P55C, AMD-K6, and Cyrix 6x86L/MX. This

board is designed to detect the CPU voltage automatically for

P54C and P55C CPUs due to the Smart Detect CPU Voltage

function, and therefore, there is no need to move any jumpers to

set the voltage for P54C/P55C CPUs.

Hardware Setup 13

Memory Configuration

The mainboard supports two strips of 72-pin 5V FPM/EDO DRAM

(SIMM) from 4 to 32MB and two strips of 168-pin 3.3V/5V

Unbuffered DIMM modules from 8 to 128MB. The mainboard

requires SIMM modules of at least 70ns access time.

You can install memory in any combination without having to rely on a

memory configuration table. memory configuration is thus ÒTable-FreeÓ

in any memory bank. You must install two SIMM modules to complete

a bank.

Cache Configuration

The mainboard has a write-back caching scheme with built-in 512KB or

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.
