vIntroduction
The G586VPM 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 G586VPM supports a 320-pin Zero Insertion Force
(ZIF) CPU socket for PentiumTM processors running at
75MHz, 90MHz or 100MHz frequency. This ZIF socket
allows users to easily upgrade their CPUs. It also sup-
ports Flash EPROM for easy BIOS upgrades. Flash
EPROM is a memory chip for the storage of BIOS
which can be erased in bulk or modified using a soft-
ware utility.
The G586VPM is equipped with four PCI and four ISA
slots, of which one pair is shared.
Equipped with two built-in PCI IDE connectors, the
G586VPM system board can control four drives and
supports fast Mode 3 hard drives and hard drives larger
than 528MB under DOS. The system board is also
equipped with two NS16C550 serial ports, an ECP/EPP
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 256MB using
256Kx36, 512Kx36, 1Mx36, 2Mx36, 4Mx36 and
8Mx36 SIM modules.

PCI/ISASystemBoard
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 pages 2-4
and 2-5 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.

G586VPM
Precautions in Handling the System Board
It is quite easy to inadvertently damage your system
board even before installing it in your system case.
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.

Memory Installation
Installation Overview u2-2
The G586VPM system board can support 2MB to
256MB of memory using SIM modules.

PCI/ISASystemBoard
2-3 uInstallation Overview
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.
With 64-bit access, the G586VPM system board uses
256Kx36, 512Kx36, 1Mx36, 2Mx36, 4Mx36 or 8Mx36
SIMM modules. It uses 256K bit, 1M bit, 4M bit, or
16M bit depth DRAM.
The SIM sockets are divided into four 64-bit banks on
the system board. Each bank consists of 2 SIMM sock-
ets. You can insert single-sided or double-sided SIM
modules to any of the banks located on the system
board.
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.
