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 b y a battery so that it retains the Setup information when the po wer is tu rned off. Basic Input-Output System (BIOS) determines what a computer can do without access ing programs from a disk. This system controls most of the input and output devices such as ke ybo ard, mous e, ser ial ports and disk dr ives. BIOS ac tivates at the first stage of the booting process, lo ading and executing the operating system. Some additional features, such as virus and password protection or chipset fine-tuning options are also inc luded in BIOS. The rest of this manual will to guide yo u through the options and s ett ings 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 Vers ion 1.1&1.2 of th e Advanced Power Manage ment (APM) specific ation. Po wer ma nagement features are impleme nted via the System Management Interrupt (SMI). Sleep and Suspend power management modes are supported. Power to the hard dis k drives and video monitors can also be managed by this AMI BIOS.

ACPI Support

AMI ACPI BIOS support Version 1.0/2.0 of Advanced Configuration and Power interface spec if ication (AC PI). It provides ASL code for power management and device configuration capabilities as defined in the ACPI sp ecificat io n, developed by Microsoft, Intel and Toshiba.

PCI Bus Support

This AMI BIOS also suppo rts Vers ion 2.3 of the Intel PCI (Peripheral Component Interconnect) lo c a l b us s p ec ific a t ion.

DRAM Support

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

Supported CPUs

This AMI BIOS supports the AMD CPU.

Using Setup

Whe n starting up t he co mp uter, 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 descriptio n of the selected item. Navigation Keys for that particular menu are at the bottom right corner, and you c an use these keys to select it em and c hange 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 co mpatibility and stability. Use Load Setup Default under the Exit Menu.

z For better system perfo rmance, the BIOS firmware is being continuo usly updated.

The BIOS information described in this manual is for your reference only. The actual BIOS information and settings on board may b e slightly different from this manual.

z The content of this manual is sub ject to b e changed without notice. We will not be

responsible for any mistakes found in this user’s manual and any system dama ge that may b e caused by wrong-settings.
