694X PRO System Board III

VIA694X System Board 1

Chapter 1 Introduction

1-1 Main Board Overview

The main board is a new-generation INTEL Celeron/FC-PGA Pentium®III；Cyrix

MIII main board designed based on VIA VT82C694X chipset. The main board

has integrated the latest advances in processor, memory, I/O technologies into an

ATX form factor.

The main board utilizes VIA 694X chipset designed for INTEL Celeron/FC-PGA

Pentium®III；Cyrix MIII CPUs and supports new architects such as high-speed

2X/4X mode AGP graphic port, SDRAM, Ultra DMA/66, bus master IDE and

USB port. It has three Dual In-line Memory Modules (DIMM) which can be

installed with SDRAM memory. The memory subsystem supports up to either 384

MB (SDRAM). The main board using the Socket370, accepts Intel®Pentium®

II/III(100/133 MHz) processors. Built-in second level (L2) cache in CPU, there is

no cache necessary in this system board.

The main board also has implemented VIA VT82C686A high performance I/O

Controller utilizes with fully Plug and Play device which supports 2.88 MB

Floppy, Dual 16550 Compatible (with 16 bytes FIFO, up to 460K baud rate)

Serial Port, ECP (Enhanced Capabilities Port), EPP (Enhanced Parallel Port)

parallel port, Infrared IrDA (HPSIR), Amplitude Shift Keyed IR. (ASKIR) port

and Audio.

The main board supports 5*PCI, 1*A.G.P and 1*AMR. (four PCI Bus Mastering

slots & 1 PCI Bus Slave slot) for highest performance I/O add-on adapter cards.

VIA694X System Board 2

The main board is also strengthened with Power Management Wake up Event

such as “WOL (Wake up on LAN),” “Modem ring on” which are the new

inventions to enable PCs to be turned on over the network. These are also key

benefits in PC operation, asset management, new system setup and power

conservation.

In conclusion, the main board is a combination of the highest in performance,

flexibility, efficiency, and ease of use that meets a variety of price/performance

levels. The main board is an ideal platform for the increasing requirements of

today’s and future’s desktop application.



This main board supports to 4X mode AGP card specially.

VIA694X System Board 4

● Green function : Complied with APM (Advanced Power Management)

● ATX form factor

The ATX form factor has been defined to address four major areas of

improvement required of today’s predominant form factors.

•Enhance PC ease-of-use with all built-in I/O connector

•Better support for current and future I/O

•Reduce total system cost

•Better support for future processor technology

ATX is an evolution of the popular Baby-AT form factor. By mounting the

power supply on its side, the processor is relocated away from the expansion

slots, and the longer side of the board is used to host more on-board I/O

connector; this placing of I/O on the board reduces cabling inside the box,

lower costs, and improves reliability and ease-of use. A flexible I/O panel

allows ATX to support all current and future I/O requirements. The ATX

power supply will directly suck the air out of chassis that will save the cost of

a secondary fan in the system. System cost is further reduced by the higher

integration of PC components onto the system board itself, saving materials,

inventory holding, and assembly cost.

● Power supply regulation

Onboard switching voltage that supports appropriate power to the CPU and

future upgraded CPUs.
