Hardware Installation

This section will assist you in quickly installing your system hardware. Wear a wrist ground strap
before handling components. Electrostatic discharge may damage your system components.

CPU Processor Installation

This mainboard supports AMD® processors using a Socket A. Before building your system, we
suggest you visit the AMD

http://www.amd.com

CPU Socket A Configuration Steps:

1. Locate the CPU socket on your mainboard and nudge the lever away from the socket. Then lift
the lever to a 90-degree angle.

2. On the socket, locate the corner that has the pin-1 receptor. This corner will be near to the end of
the lever. Match the corner on the CPU with the pin-1 receptor on the socket and lower the CPU
onto the socket. The bottom of the CPU should be flush with the face of the socket.

3. Lower the lever until it snaps back into position. This will lock down the CPU.

4. Smear thermal grease on top of the CPU. Lower the CPU fan onto the CPU and use the clasps on
the fan to attach it to the socket. Finally, extend the power cable from the fan and insert it onto the
CPUFAN adapter.

®

website and review the processor installation procedures.

Three power headers are available for cooling fans, which play an important role in maintaining the
ambient temperature in your system.

Attention

This system has a BIOS configuration feature that issues a warning
(during POST) when the CPU fan is not plugged in or is no
functioning. In order to make use of this feature. You must make sure
that the CPU power cable is attached specifically to the “CPUFAN”
header. The BIOS configuration option is described in the “Hardware
Monitor” section of the BIOS Setup Utility Chapter.

Memory Installation

The mainboard contains 2 sockets, which use 184 pin DDR SDRAM with a total memory capacity of
up to 2 GB. You can install unbuffered & non-ECC DDR400/ 333/ 266/ 200 (PC3200/ 2700/ 2100/

Chapter 2. BIOS Setup

Introduction

This section describes PHOENIX-AWARD™ BIOS Setup program which resides in the ROM BIOS
firmware. The Setup program allows users to modify the basic system configuration. The
configuration information is then saved to CMOS RAM where the data is sustained by Li-battery
after power-down.

The BIOS provides critical low-level support for standard devices such as disk drives, serial ports
and parallel ports. As well, the BIOS controls the first stage of the boot process, loading and
executing the operating system.

The PHOENIX-AWARD
standard BIOS. This means that it supports the BIOS of AMD

This version of the PHOENIX-AWARD™ BIOS includes additional features such as virus and
password protection as well as special configurations for fine-tuning the system chipset. The defaults
for the BIOS values contained in this document may vary slightly with the version installed in your
system. (When you boot up the computer, the BIOS version will appear at up-left of the POST
screen.)

Appendix II: SATA RAID 0/1 Setup

Introduction to RAID
(Redundant Array of Independent Disks)

RAID technology is a sophisticated disk management system that manages multiple disk drives,
enhancing I/O performance and providing redundancy in order to prevent the loss of data in case any
of the individual disks fail. The SATA RAID facility on this board provides RAID 0 (striped), RAID
1 (mirrored) and RAID SPAN.

Disk Striping (RAID 0)

Striping is a performance-oriented, non-redundant disk storage technology. With RAID striping,
multiple disks are used to form a larger virtual disk. Data is then striped or mapped across all the
physical disks. In this way modern SATA and ATA bus mastering technology can be used to perform
multiple I/O operations in parallel, enhancing performance. While Striping is discussed as a RAID
Set type, it actually does not provide fault tolerance.

Disk Mirroring (RAID 1)

With Disk Mirroring there is a redundant disk that mirrors the main disk. Data that is written to the
main disk is also written to the redundant disk. This redundancy provides fault tolerant protection
from a single disk failure. If a read/write failure occurs on one drive, the system can still read and
write data using the other drive.

RAID SPAN

RAID SPAN is not one of the standard RAID levels. It is however considered a JBOD (Just Bundle
Of Disks) configuration which simply uses multiple disks to form a larger virtual disk without any
other specialized disk management functionality.

RAID BIOS Configuration

When the system boots up during the POST (Power-On Self Test), the user will be given an
opportunity to enter the “VIA RAID BIOS Configuration” utility. Wait for the following prompt:

Press <Tab> Key into User Window

Then press the “Tab” key to enter the VIA RAID BIOS Configuration utility. The VIA RAID BIOS
screen will display as shown below.
