Introduction

This mainboard is a versatile high-end and workstation class

product with an ATX form factor. The mainboard features dual

Socket 370 CPU sockets which uses an Intel CeleronTM PPGA/FC-

PGA series processors, or dual FC-PGA Pentium III series

processors, or a Cyrix III series processors at 66/100/133MHz

FSB.

The mainboard incorporates the VIA 82C694X and VT82C686B

chipsets, features an AC97 audio codec built-in. The mainboard

delivers high-level performance with a 4xAGP (Accelerated

Graphics Port) slot and two us Master Ultra DMA (UDMA) ports

that support four ATAPI (AT Attachment Packet Interface)

devices. The IDE also supports PIO Mode 3 and 4,

UDMA33/66 100 IDE, and an ATAPI CD-ROM.

The mainboard also has a full set of ATX I/O ports, such as two serial

port connectors, a parallel port connector, a dual US (Universal

Serial us) connector, and PS/2 keyboard and mouse connectors. An

extra US header gives you the option of connecting two more US

ports.

One AGP slot, four PCI local bus slots, and one AMR riser slot

provide expandability for add-on peripheral cards.

Static Electricity Precautions

Components on this mainboard can be damaged by static

electricity. Take the following precautions when unpacking the

mainboard and installing it in a system.

1. Keep the mainboard and other components in their original

static-proof packaging until you are ready to install them.

2. During installation, wear a grounded wrist strap if possible. If

you don’t have a wrist strap, discharge static electricity by

touching the bare metal of the system chassis.

3. Handle the mainboard carefully by the edges. Avoid touching

the components unless it is absolutely necessary. During

installation put the mainboard on top of the static-protection

packaging it came in with the component side facing up.

Pre-Installation Inspection

1. Inspect the mainboard for damage to the components and

connectors on the board.

2. If you suspect that the mainboard has been damaged, do not

connect power to the system. Contact your mainboard vendor

and report the damage.
