Introduction

Expansion Slots

• 1 AGP slot

• 3 PCI slots

AGP (Accelerated Graphics Port)

AGP is an interface designed to support high performance 3D

graphics cards. It utilizes a dedicated pipeline to access system

memory for texturing, z-buffering and alpha blending. The universal

AGP slot supports AGP 8x with up to 2.13GB/sec. bandwidth and

AGP 4x with up to 1066MB/sec. bandwidth for 3D graphics applica-

tions. AGP in this system board will deliver faster and better graph-

ics to your PC.

• AC’97 supported with full duplex, independent sample rate con-

verter for audio recording and playback

• S/PDIF-out interface

• 6-channel audio output

S/PDIF-out

S/PDIF is a standard audio file transfer format that transfers digital

audio signals to a device without having to be converted first to an

analog format. This prevents the quality of the audio signal from

degrading whenever it is converted to analog. S/PDIF is usually

found on digital audio equipment such as a DAT machine or audio

processing device.The S/PDIF connector on the system board sends

surround sound and 3D audio signal outputs to amplifiers and

speakers and to digital recording devices like CD recorders.

6-channel Audio

The 6-channel audio output function is supported by configuring

the audio software application program.

Serial ATA

Serial ATA is a storage interface that is compliant with SATA 1.0

specification. With speed of up to 1.5Gbps, it improves hard drive

performance even in data intensive environments such as audio/

video, consumer electronics and entry-level servers.

• Two SATA (Serial ATA) interfaces which are compliant with

SATA 1.0 specification (1.5Gbps interface)

PCI Bus Master IDE Controller

• Supports ATA/33, ATA/66, ATA/100 and ATA/133 hard drives

• UDMA Modes 3, 4, 5 and 6 Enhanced IDE (data transfer rate

up to 133MB/sec.)

• Bus mastering reduces CPU utilization during disk transfer

• Supports ATAPI CD-ROM, LS-120 and ZIP

Introduction

USB Ports

The system board supports USB 2.0 and USB 1.1. USB 1.1 sup-

ports 12Mb/second bandwidth while USB 2.0 supports 480Mb/sec-

ond bandwidth providing a marked improvement in device transfer

speeds between your computer and a wide range of simultaneously

accessible external Plug and Play peripherals.

BIOS

• Award BIOS, Windows®98/2000/ME/XP Plug and Play compat-

ible

• Supports SCSI sequential boot-up

• Flash EPROM for easy BIOS upgrades

• Supports DMI 2.0 function

• 2Mbit flash memory

Desktop Management Interface (DMI)

The system board comes with a DMI 2.0 built into the BIOS. The

DMI utility in the BIOS automatically records various information

about your system configuration and stores these information in the

DMI pool, which is a part of the system board's Plug and Play BIOS.

DMI, along with the appropriately networked software, is designed

to make inventory, maintenance and troubleshooting of computer

systems easier. Refer to chapter 4 for instructions on using the DMI

utility.

Rear Panel I/O Ports (PC 99 color-coded connectors)

• Four USB 2.0/1.1 ports

• One RJ45 LAN port (KM400A-MLV/KM400-MLV only)
