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. T he power of CMOS
RAM is supplied by a battery so that it retains theSetup 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 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.
Plugand Play Support
ThisAMI BIOS supports the Plug and Play Version 1.0A specification.
EPA Green PC Support
ThisAMI 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
(APM) speci fication. Power management fe atures are implemented via the System
Management Int errupt (SMI). Sleep and Suspend power man agement 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 specifi cation (ACPI). It provides ASL code for power management and
device configuration capabilities as defined in the ACPI specification, developed by
Microsoft, Intel and Toshiba.

PCI Bus Support
This AMI BIOS also supports Version 2.3 of the Intel PCI (Peripheral Component
Interconn ect) local bus speci fication.
DRAM Support
DDR2 SDRAM (Double Data Rate II Synchronous DRAM) is supported.
Supported CPUs
ThisAMI BIOS supports the AMD CPU.
Using Setup
W hen 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
use these keys to select item and ch ange
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 perform ance, the BIOS firmware is being continuously updated.
The BIOS information described in this manual isfor your reference only. The actual
BIOS information and settings on board may be slightly different from this manual.
zThe 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.
