PCI/ISASystemBoard
vIntroduction
The 586OP system board offers several advanced fea-
tures 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 586OP supports a 273-pin Zero Insertion Force
(ZIF) CPU socket for PentiumTM processors running at
60MHz or 66MHz frequency. This ZIF socket allows
users to easily upgrade their CPUs. It also supports a
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 software utility.
The 586OP is equipped with four PCI and four ISA
slots, of which one pair is shared.
Equipped with two built-in PCI IDE connectors, the
586OP system board can control four drives and sup-
ports fast Mode 3 hard drives and hard drives larger
than 528MB under DOS. The system board is also
equipped with two serial ports, an ECP/EPP parallel
port, a floppy disk drive controller, and one mini-DIN-6
connector for the PS/2 mouse.
The 586OP can be configured to twenty-two different
memory sizes ranging from 2MB to 128MB using
256Kx36, 512Kx36, 1Mx36, 2Mx36, 4Mx36 and
8Mx36 72-pin SIM modules.

Introduction u1-4

PCI/ISASystemBoard
vInstallation Overview
This chapter summarizes the steps in installing the
586OP 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 2-3
and 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 operational capabilities
of your 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 586OP system board care-
fully.
2-1 uInstallation Overview

586OP
Handling the System Board
It is quite easy to inadvertently damage your system
board even before installing it to 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.
Hardware Installation
Memory Installation
The 586OP system board can support 2MB to 128MB
of memory using SIM modules.
InstallationOverview u2-2

PCI/ISASystemBoard
2-3 uInstallation Overview
An SIM module consists of several RAM chips soldered
onto a small circuit board. An SIM module connects to
the system board via a 72-pin card-edge connector.
The SIM sockets are divided into two banks on the
system board. The 586OP system board uses 256Kx36,
512Kx36, 1Mx36, 2Mx36, 4Mx36 and 8Mx36 HSIM
modules.
You will need 2 or 4 pieces of SIM modules, depending
on the amount of memory you intend to install. Your
system board can be configured with 2MB, 4MB, 6MB,
8MB, 10MB, 12MB, 16MB, 18MB, 20MB, 24MB,
32MB, 34MB, 36MB, 40MB, 48MB, 64MB, 66MB,
68MB, 72MB, 80MB, 96MB or 128MB of onboard
memory.
To install the SIM modules, first populate Bank 0 and
then Bank 1. Failure to do so will cause the system
board to work improperly.
The following table summarizes the bank locations and
modules needed for the corresponding memory sizes.
Each bank consists of 2 SIMM sockets.

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.
