PCI/ISA System Board
v Introduction
The G586OPC 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 G586OPC provides a 321-pin Zero Insertion Force
(ZIF) CPU socket for PentiumTM processors running at
75MHz, 90MHz, 100MHz, 120MHz, 133MHz or
150MHz frequency. This ZIF socket allows users to
easily upgrade their CPUs. It also provides a VRM
(Voltage Regulation Module) header allowing you to
upgrade to future low-voltage CPUs.
The G586OPC is equipped with three PCI slots, three
ISA slots and one shared PCI/ISA slot.
The G586OPC 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/EPP/ECP
parallel port, a floppy disk drive controller, one PS/2
mouse port and one PS/2 keyboard connector.
The G586OPC can support 2MB to 128MB of memory
using 256Kx36, 512Kx36, 1Mx36, 2Mx36, 4Mx36 and
8Mx36 72-pin SIM modules.

v Installation Overview
This chapter summarizes the steps in installing the
G586OPC 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 8
and 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 attract static electricity which can damage some circuits on your system
board.
G586OPC
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
6
PCI/ISA System Board
ideal location, unpack the G586OPC system board
carefully.
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 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 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
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
Memory Installation
The G586OPC system board can support 2MB to
128MB of memory using 72-pin SIMMs (Single In-Line
Memory Module).
The SIMM sockets are divided into two banks on the
system board. The G586OPC system board uses
256Kx36, 512Kx36, 1Mx36, 2Mx36, 4Mx36 and
8Mx36 SIMMs. Non-parity (x32) SIMMs can also be
used if parity checking is turned off in CMOS setup.
You will need 2 or 4 pieces of SIMMs, depending on
the amount of memory you intend to install.
G586OPC
To install the SIM modules, first populate Bank 0 and
then Bank 1, or the system will not work.
The table on the next page summarizes the bank locations and modules needed for the corresponding memory
sizes. Each bank consists of 2 SIMM sockets.

Installing the Modules
A SIMM simply snaps into a socket on the system
board. Pin 1 of the SIMM 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.

Board Configuration
The G586OPC has jumpers and connectors onboard.
Make sure the jumpers are set correctly before installing
the system board into your system unit.

stored in the ROM BIOS. To load the default values,
switch off your computer and remove the cover. Touch
the power supply box to discharge any static electric
buildup in your body. Set JP11 to On for approximately
5 seconds, then return to the default position (Off). Put
the cover back and power up your system.

The G586OPC system board can support either asynchronous cache SRAM or synchronous (pipelined

256KB, 512KB and 1MB. 256KB is the default size.
Installing Asynchronous Cache SRAM
The SRAM sockets allow you to install either 32Kx8,
64Kx8 or 128Kx8 SRAM. Regardless of the amount of
cache memory installed, one 32Kx8 (U23) is needed for
tag RAM to store the cacheable addresses. The locations
of the SRAM sockets on the system board are shown on
the next page.
