Brief Introduction
AthlonTM Processor
The AMD AthlonTM is a seventh-generation micro architecture with an integrated
L2 cache, which is powerful enough to support the bandwidth requirements of a
large range of applications, hardware, graphics, and memory technologies.
For more information about all the new features AthlonTM Processor deliver, check out
the AMD website at http://www.amd.com
Chipset
The board is designed with VIA chipset, KT880 as North Bridge and VT8237 as
South Bridge, providing a feature rich and scalable platform.
The North Bridge connects to the South Bridge through the fast Ultra V-Link
connection at 1.06GB/s. With support for two Serial ATA channels at 150MB/s
bandwidth, integrated RAID (0, 1 & JBOD) capability as well as up to eight USB
2.0 ports, the VT8237 offers the highest possible peripheral performance for
professional users. Additional features include a VIA MAC for 10/100Mbps Fast
Ethernet, integrated PCI support.
For more details about the VIA chipset features, please visit the VIA Web site at
http://www.via.com.
Accelerated Graphics Port (AGP)
The AGP slot on the board is compliant with the new AGP 3.0 specification. This
new specification enhances the functionality of the original AGP specification
by allowing 8X data transfers ( 8 data samples per clock) resulting in maximum
bandwidth of 2.1GB/s. Only 1.5V AGP cards are supported.
Ultra ATA100/133
The mainboard provides an Ultra ATA100/133 Bus Master IDE controller. This
controller supports Ultra ATA100/133 protocols which are ideal to support
demanding applications such as real-time video, multimedia, and a high perfor-
mance operating system. A new IDE cable is required for Ultra ATA100/133.
Hardware Monitoring
Hardware monitoring enables you to monitor various aspects of the system
operation and status. This includes CPU temperature, voltage and fan speed in RPMs.

Introduction
Page 1-3
10/100 LAN
This mainboard is mounted with an ethernet LAN PHY. It allows the mainboard to
connect to a local area network by means of a network hub.
Serial ATA
Support Serial ATA, an evolutionary replacement for Parallel ATA IDE storage
interface .Increases the peak data transfer speed up to 150MB/sec and allows
future enhancements to the computing platform.
USB2.0
A popular USB standard for plugging in peripherals with up to 480Mbps transfer
speed while maintaining backward compatibility with older USB1.1 device.
6ch
Delivers 6 channel audio to bring you the latest in audio realism from DVD
movies and games. Perfect for your home theatre system.
QuickSPDIF
On board SPDIF-out connector for quick connection to multi-channel speakers.
Not only removes cable cluttering but also delivers loss-free digital audio to let
you enjoy DVD movies and games with crystal clear sound.
Magic Health
Reports your system hardware status for every boot-up to help detect faults
early. Monitor hardware status including CPU temperature, CPU/Memory
voltage, fan RPM speed for chassis fan, CPU fan & Power supply fan.
EZ-Boot
Simply press “ESC” to select your bootable device. No more hassle to search the
BIOS menu, change and re-start.
PowerBIOS
Supporting a full range of overclocking setting via BIOS. Various adjustable
feature include FSB/Memory voltage tweaking.
