vFCC Statement on Class B
This equipment has been tested and found to comply
with the limits for a Class B digital device, pursuant to
Part 15 of the FCC rules. These limits are designed to
provide reasonable protection against harmful interfer-
ence when the equipment is operated in a residential
installation. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and
used in accordance with the instruction manual, may
cause harmful interference to radio communications.
However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does
cause harmful interference to radio or television recep-
tion, which can be determined by turning the equipment
off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and
the receiver.
•Connect the equipment into an outlet on a circuit
different from that to which the receiver is
connected.
•Consult the dealer or an experienced radio TV
technician for help.
Notice:
1. The changes or modifications not expressly
approved by the party responsible for compliance
could void the user's authority to operate the

vIntroduction
The G586IPB/W 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 G586IPB/W provides a 321-pin Zero Insertion
Force (ZIF) CPU socket for PentiumTM processors
running at 75MHz, 90MHz, 100MHz, 120MHz,
133MHz or 150MHz frequencies. This ZIF socket
allows users to easily upgrade their CPUs. It also pro-
vides a VRM (Voltage Regulation Module) header
which lets you to upgrade to future low-voltage CPUs.
The G586IPB/W is equipped with four PCI slots and
three ISA slots.
The G586IPB/W 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 parallel
port, a floppy disk drive controller, one PS/2 mouse port
and one PS/2 or AT keyboard connector.
The G586IPB/W can support 8MB to 128MB of
memory using 1Mx36, 2Mx36, 4Mx36 and 8Mx36 72-
pin SIM modules.

Slot Limitations
Due to the size of the CPU with its accompanying
heatsink/fan component, the length of the add-in
cards in PCI slots 2, 3 and 4 is limited to 205mm
(measured from the bracket of the card).
The length of the add-in card in PCI slot 1 is
limited to 205mm only if its components protrude
more than 5mm from the components and/or solder
side of the card.

vInstallation Overview
This chapter summarizes the steps in installing the
G586IPB/W 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 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 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 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 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
