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

reception, 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

equipment.

vIntroduction

The G486VPA 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 G486VPA is an Enetgy 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 G486VPA system board supports a 237-pin Zero

Insertion Force (ZIF) CPU socket that allows users to

easily upgrade their CPUs. It also supports a 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 G486VPA is equipped with three PCI slots, three

ISA slots and one shared PCI/ISA slot.

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

one ISA IDE connector, the G486VPA system board can

control four drives and supports fast Mode 3 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 mini-DIN-6 connector for the PS/2 mouse.

The G486VPA can support 1MB to 128MB of memory

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

8Mx36 and 16Mx36 72-pin SIM modules.
