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

acc essing 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 proc ess, loading and executing the operating syst em. Som e
additional features, such as virus and password protection or chipset fine-tuning
options are also included 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 AM I BIOS supports the P lug and Play Version 1.0A specification.

EPA Green PC Support

T his AM I BIOS supports Version 1.03 of the EPA Green PC specification.

APM Support

This AMI BIOS supports Version 1.1&1.2 of the Advanced Power Management
(AP M) speci fic ati on. Power m anagement fe atures a re implem ent ed vi a the Sy stem

Management Interrupt (SMI). Sleep and Suspend power management modes are
supported. Power to the hard disk drives and video monitors can also be m anaged by
this AMI BIOS.

ACPI Supp ort

AMI ACPI BIOS support Version 1.0/2.0 of Advanced Configuration and Power
interface specifi cation (ACP I). It provides ASL code for pow er management and
device configuration capabilities as defined in the ACPI specific ation, developed by
Microso ft, Intel and T oshiba.

PCI Bus Support

T his AMI BIOS also supports Version 2.3 of the Intel P CI (Peripheral Component
Int erconn ect ) local b u s s p eci fic atio n .

DRA M Support

DDR2 S DRAM (Double Data Rate II S ynchronous DRAM) is supported.

Su ppor t e d CP Us

T his AM I BIOS supports the AMD C P 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 these keys to sele ct it em and ch ange
the settings.

Notice

z T he default BIOS settings apply for most conditions to ensure optimum performance

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 S etup Default under the Exi t Menu.

z For better system per form ance, the BIOS firmware is being continuously updated.

T he BIOS information described in this manual is for your re ference only. The actual
BIOS information and settings on board may be slightly different from this manual.

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

responsible for any mistakes found in t his user’s manual and any system damage that
may be caused by wrong-settings.
