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 abattery so that it retains theSetup informationwhen 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 protection 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.
Plugand Play Support
ThisAMI BIOS supports thePlug and Play Version 1.0A specification.
EPA Green PC Support
ThisAMI BIOS supports Version 1.03 of the EPAGreen PC specification.
APM Support
This AMI BIOS supports Version 1.1&1.2 of the Advanced Power Management
(APM) speci fication. Power management features are implemented via the System
Management Interrupt (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 ACPI BIOS support Version 1.0/2.0 of Advanced Configuration and Power
interface specification (ACPI). It provides ASL code for power management and
device configuration capabilities as defined in theACPI specification, developed by
Microsoft, Intel and Toshiba.

Using Setup
When starting up the computer, press
<Del> during the Power-On Self-Test
(POST) to enter theBIOS 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 select item and change
the settings.
Notice
zThe 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.
zFor better system performance, the BIOS firmware is being continuously updated.
The BIOS information described in this manual isfor yourreferenceonly. The actual
BIOS information and settings on board may be slightly different from this manual.
zThe content ofthis 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
