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 m ost 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, 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 Play Support

T his AMI BIOS supports the Plug 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.

ACPI Support

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

device con figuration capabilities as defined in the ACPI specification, developed by Microso ft, Intel and Toshiba.

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 sp eci ficati on .

DRAM Support

DDR3 SD R AM (Do uble Dat a Rate III Sy nch ron ous D R A M) is suppo rted .

Su ppor t e d CP Us

T his AMI BIOS supports the Intel CPU.

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 s ele ct it em and ch ange the settings.

Notice

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

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 Exit Menu.

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

T he BIOS information described in t his manual is for your reference only. T he actual BIOS information and setti ngs on board may be sli ghtly different from thi s manual.

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

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