vIntroduction
The G586IPBS 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 G586IPBS 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.
It is equipped with four PCI slots and three ISA slots.
The system board has two bus master PCI IDE connectors.
Bus mastering reduces CPU use during disk transfer. The
system board is also equipped with two NS16C550-compat-
ible serial ports, an SPP/EPP/ECP parallel port, a floppy disk
drive controller, one PS/2 mouse port and one PS/2 or AT
keyboard connector.
The G586IPBS can support 8MB to 128MB of memory
using 1Mx36, 2Mx36, 4Mx36 and 8Mx36 72-pin SIM
modules.

vInstallation Overview
This chapter summarizes the steps in installing the
G586IPBS 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, 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 electric-
ity. 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.
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 ideal
location, unpack the G586IPBS 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 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 G586IPBS system board can support 8MB to 128MB of
memory using 72-pin SIMMs (Single In-line Memory Mod-
ule).
The SIM sockets are divided into two banks on the system
board. Each bank consists of 2 SIMM sockets. The
G586IPBS 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.
11
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 45oangle into the bank. Make sure
it is completely seated. Tilt the module upright until it
locks in place in the socket.

Jumper JP2
Password Clear
If you set a password in the “Password Setting” option and
forget your password, power off your system and set Jumper
JP2 to On to clear the password stored in your CMOS. Now
power on your system. After your system has detected the
floppy or hard drive, turn it off again and set JP2 to Off.

Jumper JP3 sets the display adapter to color or mono. This
jumper must match the type of display adapter installed. If
you change your video adapter, make sure this jumper is
changed accordingly.
