BIOS Setup

Introducti on

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
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 system. Some
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 AMI BIOS supports the P lug and Play Version 1.0A specific ation.

EPA Green PC Support

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

APM Supp ort

This AMI BIOS supports Version 1.1&1.2 of the Advanced Power Management
(AP M) speci fic ation . Pow er manag ement fe atures a re implem ented vi a the System

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

this AMI BIOS.

ACPI Supp ort

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
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 us speci fi cat io n .

DRA M Support

DDR2 S DR AM (Double Data Rat e II Synchronous DRAM) i s supported.

Su ppor t e d CP Us

T his AMI BIOS supports the Intel 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 th ese key s t o sel ect item and ch ange
the settings.

Notice

z T he default BIOS settings apply for most conditions to ensure optimum perform 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 Default under the Exit Menu.

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

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

z T he content of this manual is subject to be chang ed without notice. W e will not be

responsible for any mist akes found in this user’s manual and any system damage that
may be caused by wrong-settings.
