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 R AM. 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. 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 process, loading and executing the operating system. Som e 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 AM I BIOS supports the Plug and Play Version 1. 0A specific ation.

EPA Green PC Support

T his AM I 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 (ACP I). It provides ASL code for power management and

device configuration capabilities as defined in the ACPI specification, developed by Microso ft, Intel and T oshiba.

P43-A7/ P45D2 - A7 BIOS Manual

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 fi cati o n.

DRA M Support

DDR2 S DRAM (Double Data Rate II S ynchronous DR AM) is supported.

Su ppor t e d CP Us

T his AM I BIOS supports the Int el 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 t he bottom right corner, and you can us e thes e keys to select i tem an d ch ange the settings.

Notice

z T he 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 S etup Default under the Exit Menu.

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

T he BIOS information described in this manual is for your refer ence only. The actual BIOS information 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. We will not be

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