vIntroduction

The G486VPB 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 G486VPB 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

when not in use.

The G486VPB system board supports a 237-pin Zero

Insertion Force (ZIF) CPU socket that allows users to

easily upgrade their CPUs. It also supports an optional

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 G486VPB is equipped with four PCI slots, four ISA

slots (one shared PCI/ISA slot).

Equipped with one built-in VL-bus IDE connector and

one ISA IDE connector, the G486VPB system board can

control four drives and supports fast Mode 4 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 optional mini-DIN-6 connector for the PS/2

mouse.

The G486VPB can support 1MB to 128MB of memory

using 256Kx36, 512Kx36, 1Mx36, 2Mx36, 4Mx36,

8Mx36 and 16Mx36 72-pin SIM modules.

vInstallation Overview

This chapter summarizes the steps in installing the

G486VPB system board into your system unit.

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 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.

Make 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 recommend 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 damage

your system board. Once you have selected the ideal

location, unpack the G486VPB 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.
