v Introduction

The G586IPB/W system board offers several advanced

features integrated into the system board. Its design is

based on the new Peripheral Component Interconnect

(PCI) local bus and Industry Standard Architecture

(ISA) standards.

The G586IPB/W provides a 321-pin Zero Insertion

Force (ZIF) CPU socket for Pentium

TM

processors

running at 75MHz, 90MHz, 100MHz, 120MHz,

133MHz or 150MHz frequencies. This ZIF socket

allows users to easily upgrade their CPUs. It also pro-

vides a VRM (Voltage Regulation Module) header

which lets you to upgrade to future low-voltage CPUs.

The G586IPB/W is equipped with four PCI slots and

three ISA slots.

The G586IPB/W board has two bus master PCI IDE

connectors. Bus mastering reduces CPU use during disk

transfer. The system board is also equipped with two

NS16C550A-compatible serial ports, an SPP parallel

port, a floppy disk drive controller, one PS/2 mouse port

and one PS/2 or AT keyboard connector.

The G586IPB/W can support 8MB to 128MB of

memory using 1Mx36, 2Mx36, 4Mx36 and 8Mx36 72-

pin SIM modules.

v Installation Overview

This chapter summarizes the steps in installing the

G586IPB/W system board into your system unit. It also

includes a description of the area in which you must

work and directions for memory installation. Before

installing the system board, obtain the memory you plan

to install. Please refer to the memory chart on page 9 for

the number and type of SIM modules needed for the

amount of memory you require.

Preparing the Area

Before unpacking the system board, make sure the

location you have selected is relatively free of dust and

static electricity. Excessive exposure to dust, static

electricity, direct sunlight, excessive humidity, extreme

cold, and water can damage the operational capabilities

of your system board. Avoid placing the unit on surfaces

such as carpeted floors. These areas also attract static

electricity which can damage some circuits on your

system board.

Make sure the power source has a properly grounded,

three-pronged socket. It is essential that the power

connection be properly grounded for correct functioning

of your system board. For further protection, we recom-

mend that you use a surge suppressor. This will protect

the system board from damage that may result from a

power surge on the electrical line.

Move items that generate magnetic fields away from

your system board since magnetic fields can also

damage your system board. Once you have selected the

G586IPB/W

6

ideal location, unpack the G586IPB/W system board

carefully.

Handling the System Board

It is quite easy to inadvertently damage your system

board even before installing it in your system unit.

Static electrical discharge can damage computer compo-

nents without causing any signs of physical damage.

You must take extra care in handling the system board

to ensure against electrostatic build-up.

Tips in Handling the System Board

1. To prevent electrostatic build-up, leave the board in

its anti-static bag until you are ready to install it.

2. Wear an antistatic wrist strap.

3. Do all preparation work on a static-free surface with

components facing up.

4. Hold the system board by its edges only. Be careful

not to touch any of the components, contacts or

connections, especially gold contacts, on the board.

5. Avoid touching the pins or contacts on all modules

and connectors. Hold modules and connectors by

their ends.

Warning:

Electrostatic discharge (ESD) can damage your upgrade

processor, disk drives, add-in boards, and other

components. Perform the upgrade instruction

procedures described at an ESD workstation only. If

such a station is not available, you can provide some

G586IPB/W

7

ESD protection by wearing an antistatic wrist strap and

attaching it to a metal part of the system chassis. If a

wrist strap is unavailable, establish and maintain

contact with the system chassis throughout any

procedures requiring ESD protection.

Hardware Installation

If you are installing the G586IPB/W system board,

follow the instruction below. Before installing the

system board into your system unit, you should prepare

the tools you will need:

You will need:

• one medium size, flat-bladed screwdriver

• one medium Phillips screwdriver

Step 1

Unlock your system unit. Turn off the power and discon-

nect all power cords and cables.

Step 2

Remove the system unit cover. Refer to the

manufacturer’s instructions if necessary.

Step 3

Remove expansion cards seated in any of the expansion

slots and detach all connectors from the old system

board.

G586IPB/W

Step 4

Loosen the screws holding the original system board and

remove the board from the system. Save the screws.

Step 5

Remove the G586IPB/W from its original packing

box. Be careful to avoid touching all connectors and

pins on the board. Please refer to the handling

instructions on pages 6-8 for proper handling

techniques.

Step 6

Insert the SIMMs into the SIMM banks on the

G586IPB/W. The quantity and location of the SIMMs

is dependent upon the memory configuration and type

of modules you intend to use.

Step 7

Install the CPU. Be sure pin 1 of the CPU is aligned

with pin 1 of the socket.

Step 8

Set the corresponding jumpers.

Step 9

Install the prepared G586IPB/W system board into the

case and replace the screws.

Step 10

Reinstall all cards and connectors and replace the sys-

tem unit cover. Reconnect all power cords and cables.

Memory Installation

The G586IPB/W system board can support 8MB to

128MB of memory using 72-pin SIMMs (Single In-line

Memory Module).

The SIM sockets are divided into two banks on the

system board. Each bank consists of 2 SIMM sockets.

The G586IPB/W system board uses 1Mx36, 2Mx36,

4Mx36 and 8Mx36 SIMMs. You will need 2 or 4 pieces

of SIM modules, depending on the amount of memory

you intend to install.

The table on the next page summarizes the bank loca-

tions and modules needed for the corresponding memory

sizes.

Installing the Modules

A SIM module simply snaps into a socket on the system

board. Pin 1 of the SIM module must correspond with

Pin 1 of the socket.

1. Position the SIMM above the socket with the

“notch” in the module aligned with the “key” on the

socket.

2. Seat the module at a 45

o

angle into the bank. Make

sure it is completely seated. Tilt the module upright

until it locks in place in the socket.
