Chapter 1 Introduction

This motherboard has a Socket-478 to support Intel Pentium 4 processors

with Hyper-Threading Technology and Front-Side Bus (FSB) speeds up to

800 MHz. Hyper-Threading Technology, designed to take advantage of the

multitasking features in Windows XP, gives you the power to do more things at

once.

It integrates the VIA P4M800 Northbridge and VT8237 Southbridge that

supports the Serial ATA interface for high-performance and maiinstream

desktop PCs; the built-in USB 2.0 providing higher bandwidth, implementing

Universal Serial Bus Specification Revision 2.0 and is compliant with UHCI

1.1 and EHCI 0.95. It supports AC’ 97 Audio Codec and provides Ultra DMA

133/100/66 function. It has one 8X AGP, one CNR and three 32-bit PCI slots.

There is a full set of I/O ports including two PS/2 ports for mouse and keyboard,

one serial port, one parallel port, one LAN port(optional), one VGA port, three

Key Features

The key features of this motherboard include:

Socket-478 Processor

• Supports Intel Pentium 4 Series processors with Hyper-Threading

Technology

• Supports up to 800 MHz Front-Side Bus

Hyper-Threading technology enables the operating system into thinking it’s

hooked up to two processors, allowing two threads to be run in parallel, both

on separate ‘logical’ processors within the same physical processor.

Chipset

There are VIA P4M800 Northbridge and VT8237 in the chipsets in accordance

with an innovative and scalable architecture with proven reliability and perfor-

mance.

• High Performance UMA North Bridge: Integrated Pentium 4 North

Bridge with 800 MHz FSB support and UniChrome Pro 3D / 2D

Graphics & Video Controllers in a single chip

• Supports Intel 800/533/400 MHz FSB Pentium 4 and Pentium M

processors and Hyper Threading Technology
