BIOS Manual

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. The power of C MOS 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. This 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 sys tem. S ome 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 Pl ay Support

T his AMI BIOS supports the P lug and Play Version 1. 0A specification.

EPA Green PC Support

T his AMI BIOS supports Versi on 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 atu res a re im plemen ted via t he S ystem

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 B IOS.

ACPI Support

AMI ACPI BIOS support Version 1.0/2.0 of Advanced Configuration and Power interfa ce specifi cation (ACP I). It provides ASL code for pow er manag ement and

device configuration capabilities as defined in the ACPI specification, developed by Microso ft, 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 eci fic atio n .

DRAM Sup port

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

Su ppor t e d CP Us

T his AMI BIOS supports the AMD C PU.

Using Setu p

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 select it em and ch ange the settings.

Notice

z T he default BIOS settings apply for most conditions to ensure optimum per forman ce

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 Default under the Exi t Menu.

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

T he BIOS inform ation described in thi s manual is for your refer ence only. The act ual BIOS i nformation 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
