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 S etup 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. This system controls most of the input and output

devices such as keyboard, mouse, serial ports and disk drives. B IOS activates at the first st ag e o f the booting process, loading and executi ng the operating syst em. 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 B IOS Setup.

Plug and Play Support

T his AMI BIOS supports the Plug and Play Version 1.0A specific ati on.

EPA Green PC Support

T his AMI 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 anagem ent fe atu res a re im pl emented vi a the Syst em

Management Interrupt (SMI). Sleep and Suspend power management modes are supported. P ower to the hard disk drives and vi deo monit ors can also be m anaged by

this AMI BIOS.

ACPI Support

AMI ACPI BIOS support Version 1.0/2.0 of Advanced Configuration and Power interfa ce 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 Toshiba.

PCI Bus Support

T his AMI BIOS also supports Version 2.3 of the Intel PCI (Peripheral C omponent Int erconn ect ) local b u s sp eci fic atio n .

DRAM Support

DDR2 S DRAM (Double Data Rate II Synchronous DRAM) is s upported.

Su ppor t e d CP Us

T his AMI BIOS supports the Intel C P U.

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 m enu

are at the bottom right corner, and you can us e th ese keys to select it em an d ch ange the settings.

Notice

z T he default BIOS settings apply for m ost conditions to ensure optimum performan 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 Exit Menu.

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

T he BIOS inform ation described in this manual is for your reference only. The actual BIOS information and settings on board may be slightly differ ent from this manual.
