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 PentiumTM processors
running at 75MHz, 90MHz, 100MHz, 120MHz,
133MHz or 150MHz frequencies. This ZIF socket
allows users to easily upgrade their CPUs. It also provides 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.
G586IPB/W
The G586IPB/W can support 8MB to 128MB of
memory using 1Mx36, 2Mx36, 4Mx36 and 8Mx36 72pin 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.
G586IPB/W
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 recommend 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
5
G586IPB/W
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 components 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
6
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 disconnect all power cords and cables.
G586IPB/W
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.
7
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.
8
Step 10
Reinstall all cards and connectors and replace the system 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 locations 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 45o angle into the bank. Make
sure it is completely seated. Tilt the module upright
until it locks in place in the socket.

the following cache sizes: 256KB and 512KB.
Installing the Cache Module
16
← Pin 1
Cache Module Slot
G586IPB/W
1. Locate the 160-pin cache module slot on the system
board. Position the cache module above the slot.
Make sure pin 1 of the cache module is aligned with
pin 1 of the slot. Carefully slide the module into the
slot. Press firmly on the top of it to seat it properly.
Note:
You do not need to modify any jumpers when you
install the cache module.
2. Once the cache module has been installed, make
sure the “External Cache” option in the “BIOS
Features Setup” menu of the Award BIOS CMOS
Setup Utility is set to “Enabled”.
Note:
With the cache module installed in the cache
module slot, the length of the add-on card in PCI
Slot 1 is limited to 205 mm only if its components
protrude more than 5 mm from the components
and/or solder side of the card.
