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 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. This system controls most of the input and output

devices such as keyboard, mouse, serial ports and disk drives. BIOS activates at the
first stage of the booting process, loading and executing the operating system. Some
additional features, such as virus and password prot ection or chipset fine-tuning
options are also included in BIOS.
The rest of this manual will to guide you through the options and settings in BIOS
Setup.

Plug and Play Support

This AMI BIOS supports the Plug and Play Version 1.0A specification.

EPA Green PC Support

This 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 ficat ion. Power m anagement fe atures a re i mplemented via t he S yst em

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

this AMI BIOS.

ACPI Support

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

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

PCI Bus Support

This AMI BIOS also supports Version 2.3 of the Intel PCI (Peripheral Component
Int erconn ect ) local bus speci ficati on .

DRAM Sup port

DDR3 S DRAM (Double Data Rate III Synchronous DRAM) is supported.

Su ppor t e d CP Us

This AMI BIOS supports the AMD CPU.

Using Setup

W hen st arting 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
use these keys to sele ct item and ch ange
the settings.

Notice

z The 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 Setup Default under the Exit Menu.

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

The BIOS information described in this manual is for your refer ence only. The actual
BIOS information and settings on board may be slightly different from this manual.

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

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