PCI/ISASystemBoard
vIntroduction
The G586VPM system board offers several advanced
features integrated into the system board. It supports two
320-pin Zero Insertion Force (ZIF) CPU sockets for
PentiumTM processors running at 75MHz, 90MHz,
100MHz, 120MHz or 133MHz frequency. These ZIF
sockets allow users to easily upgrade their CPUs. The
G586VPM also supports Flash EPROM for easy BIOS
upgrades. Flash EPROM is a memory chip for the
storage of BIOS which can be erased in bulk or modi-
fied using a software utility.
Equipped with two built-in Bus Master PCI IDE con-
nectors, the G586VPM system board can control four
drives and supports fast PIO Modes 3 and 4 hard drives
and hard drives larger than 528MB. When the Bus
Master DMA Mode 2 IDE is enabled, the CPU utiliza-
tion rate will be highly reduced, thus taking full advan-
tage of the dual processors capability. The system board
is also equipped with two NS16C550A-compatible
serial ports, an SPP/EPP/ECP parallel port, a floppy disk
drive controller, and one mini-DIN-6 connector for the
PS/2 mouse.
The G586VPM can be configured to 22 different
memory sizes ranging from 4MB to 512MB using
256KBx32/36, 512KBx32/36, 1MBx32/36, 2MBx32/36,
4MBx32/36, 8MBx32/36 or 16MBx32/36 non-parity/
parity SIM modules.
Note:
The revision of the 75/90/100MHz processor must be
revision C2 or later. 120MHz and 133MHz for dual
processors will be supported in future revisions. Please
contact Intel or your dealer for details.

vInstallation Overview
This chapter summarizes the steps in installing the
G586VPM 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 2-4
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 system board. Avoid soft
surfaces such as beds and carpeted floors which can
hinder air circulation. These areas also attract static
electricity which can damage some circuits on your
system board.
Be sure that 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 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
ideal location, unpack the G586VPM system board
carefully.
2-1 uInstallation Overview

G586VPM
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 that no static build-up is present.
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 wriststrap.
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
ESD portection by wearing an antistatic wrist strap and
attaching it to a metal part of the system chassis. If a
Installation Overview u2-2

PCI/ISASystemBoard
wrist strap is unavailable, establish and maintain
contact with the system chassis throughout any
procedures requiring ESD protection.
Hardware Installation
Memory Installation
The G586VPM system board can support 4MB to
512MB of memory using SIM modules.
A SIM module consists of several RAM chips soldered
onto a small circuit board. A SIM module connects to
the system board via a 72-pin card-edge connector.
The SIM sockets are divided into four banks on the
system board. Each bank consists of 2 SIMM sockets.
You can insert single-sided or double-sided SIM mod-
ules to any of the banks located on the system board.
You can also populate one SIM module in a bank to
allow smaller upgrade increments.
The G586VPM system board uses 256KBx32/36,
512KBx32/36, 1MBx32/36, 2MBx32/36, 4MBx32/36,
8MBx32/36 and 16MBx32/36 SIMM modules. Your
system board can be configured with 4MB, 6MB, 8MB,
12MB, 16MB, 24MB, 32MB, 48MB, 64MB, 96MB,
128MB, 192MB, 256MB or 512MB of onboard
memory.
The following table 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 SIM module above the socket with
the “notch” in the module aligned with the “key”
on the socket.
2. Seat the module at a 45oangle into the bank.
Make sure it is completely seated. Tilt the
module upright until it locks in place in the
socket.
