1. INTRODUCTION

1.1 OVERVIEW

This Mainboard is the ATX form-factor with the Socket A CPU connector

designed on the board. VIA KT133 chipset is chosen as the system core logic of

the mainboard for the AMD Duron

and Athlon

processors. Basically,

Duron

and Athlon

are the seventh-generation micro-architecture (K7)

developed by AMD. Such processors are powerful enough to support wide range

of application for various purposes. Please refer to the following for the brief

specification of the Socket A processors:

¥ Socket A ( 462 pin PGA packing).

¥ Built-in L1 and L2 cache.

¥ Superscalar floating point unit with AMD enhanced 3Dnow!

technology.

¥ 200MHz high speed front side system bus interface.

VT82C686A (or VT82C686B) is chosen as the southern bridge of the core logic

on the mainboard. It is a high integration, power-efficient and high compatibility

device. It supports the PCI bridge functionality to make a complete PC99-

compliant PCI/ISA system. Beside the ISA extension bus functionality, there are

two channels of "PIO” and "Ultra DMA Bus Master” IDE ports to support the

most updated Ultra DMA HDD. There are one Floppy Disk controller, two high

speed Serial ports (UARTs), one multi-mode Parallel port, one PS/2™ mouse

port, one IR interface and four USB ports designed on the board for wide variety

of peripheral connection.

What is Socket A?

Basically, Socket A is the CPU connector designed for the socket type of

AMD K7

processors. There is the L2 cache memory built inside the Socket

A processor to give the most outstanding performance and reliability The

AMD K7 processor is an innovative processor designed for the value PC

market. With the AMD K7 processor, computer users will get a PC capable

of running today's applications with ease, and with enough power to run the

applications of tomorrow
