BIOS Setup

Introduction

The purpose of this manual is to describe the settings in the AMI BIOS Setup
program on this motherboard. The Setup program allows users to modify the basic

system configuration and save these settings to CMOS RAM. T he power of CMOS
RAM is supplied by a battery so that it retains the Setup information when the power
is turned off.

Basic Input-Output System (BIOS) determines what a computer can do without
accessing programs from a disk. T his system controls most of the input and output

devices such as keyboard, mouse, serial ports and disk drives. BIOS activates at the
first stag e o f the booting process , l oading and executing the operating syst em. S om e
additional features, such as virus and password protection or chipset fine-tuning
options are also i ncluded in BIOS.
T he rest of this manual will to guide you through the options and settings in BIOS
Setup.

Plug and Play Support

T his AMI BIOS supports the P lug and Play Version 1.0A specifi c ati on.

EPA Green PC Support

T his AMI BIOS supports Version 1.03 of t he EPA Green PC specification.

APM Support

This AMI BIOS supports Version 1.1&1.2 of the Advanced Power Management
(AP M) speci fic ation. Power m an agement fe atures are i mplem ented vi a the S ystem

Management Interrupt (SMI). Sleep and Suspend power management modes are
supported. Power to the hard disk drives and video m onitors can also be managed by

this AMI BIOS.

ACPI Support

AMI ACPI BIOS support Version 1.0/2.0 of Advanced Configuration and Power
interface specifi cation (ACPI). It provides ASL code for pow er management and

device con figuration capabilities as defined in the ACPI specification, developed by
Microsoft, Intel and T oshiba.

PCI Bus Support

T his AMI BIOS also supports Version 2.3 of the Intel PCI (Peripheral Component
Int erconn ect ) local b u s s p ecifi c ati o n.

DRAM Sup port

DDR2 SDR AM (Double Data Rate II Synchronous DRAM) is supported.

Su ppor t e d CP Us

T his AMI BIOS supports the AMD CP U.

Using Setup

When starting up the computer, press

<Del> during the Power-On Self-Test
(POST) to enter the BIOS setup utility.

In the BIOS setup utility, you will see
General Help description at the top right

corner, and this is providing a brief
description of the selected item.
Navigation Keys for that particular menu

are at the bottom right corner, and you can
us e thes e keys to sele ct it em and change
the settings.

Notice

z T he default BIOS settings apply for most conditions to ensure optimum per form ance

of the motherboard. If the system becomes unstable after changing any settings,
please load the default settings to ensure system’s compatibility and stability. Use

Load Setup Defaul t under the Exi t Menu.

z For better system performance, the BIOS firmware is being continuously updated.

T he BIOS information described i n this manual is for your reference only. The actual
BIOS information and settings on board may be slightly different from thi s manual.

z T he content of this manual is subject to be changed without notice. We will not be

responsible for any mistakes found i n this user’s manual and any system damage that
may be caused by wrong-settings.
