GreenPCI/ISASystemBoard
vIntroduction
The G586VPB is an Energy Star Compliant system
board that supports the Environmental Protection
Agency’s Green PC requirements. It reduces energy
consumption by automatically turning off peripherals, or
the entire system, when not in use.
The G586VPB system board offers several advanced
features integrated into the system board. Its design is
based on the Peripheral Component Interconnect (PCI)
and Industry Standard Architecture (ISA) standards.
The G586VPB supports a 320-pin Zero Insertion Force
(ZIF) CPU socket. The board supports Flash EPROM,
a memory chip for the storage of BIOS which can be
erased in bulk or modified using a software utility. The
ZIF socket allows users to easily upgrade the CPU.
The G586VPB is equipped with three dedicated PCI
slots, one shared PCI/ISA slot and three dedicated 16-bit
ISA slots.
The G586VPB can be configured to several different
sizes of memory up to 128MB using 256Kx36,
512Kx36, 1Mx36, 2Mx36, 4Mx36 and 8Mx36 SIM
modules.

vInstallation Overview
This chapter summarizes the steps in installing the
G586VPB 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 2-4
and 2-5 for the number and type of HSIM 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. 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 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 protection socket. 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 dam-
age your system board. Once you have selected the ideal
location, unpack the G586VPB system board carefully.

GreenPCI/ISASystemBoard
2-2 uInstallation Overview
Handling the System Board
It is quite easy to inadvertently damage your system
board even before installing it in 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 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) Do all preparation work on a static-free surface with
components facing up.
3) 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.
4) 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
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 portection 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 G586VPB system board can support up to 128MB
of memory using HSIM modules. HSIM is an acronym
for High Density Single In-line Memory.
An HSIM module consists of several RAM chips sol-
dered onto a small circuit board. An HSIM module
connects to the system board via a 72-pin card-edge
connector.
The SIMM sockets are divided into two banks. Bank 0
consists of SIM3 and SIM4 SIMM sockets, and Bank 1
consists of SIM1 and SIM2 SIMM sockets. Please note
that you can use either Bank 0 or Bank 1 to boot your
system.
The G586VPB system board uses 256Kx36, 512Kx36,
1Mx36, 2Mx36, 4Mx36 and 8Mx36 SIM modules.
The table on the next page summarizes the bank loca-
tions and modules needed for the corresponding memory
sizes.
Note:
Make sure that the SIMM sockets belonging to the same
Bank (e.g. SIM3 and SIM4 - Bank 0) contain the same
type of DRAM. If you instal two different types of
DRAM in one bank, the system will not boot.

Installing the Modules
An HSIM module simply snaps into a socket on the
system board. Pin 1 of the HSIM module must corre-
spond with Pin 1 of the socket.
1. Position the HSIM 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.

recharge, disassemble or dispose of in fire.
Cache Configuration
The G586VPB system board can be configured to four
different cache sizes: 256KB (Default size), 512KB,
1MB and 2MB. Either 32Kx8, 64Kx8 or 128Kx8 SRAM
chips are used for cache depending on the size of cache
desired. The G586VPB supports both pure 3.3V and
3.3/5V mixed voltage SRAM. The brands of SRAM that
passed a factory testing are shown on the next page.
