BIOS Setup
Introduction
T he 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 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. T his 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. Some
additional features, such as virus and password prot ection 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 Pla y Support
T his AMI BIOS supports the Plug and Play Version 1.0A specification.
EPA Green PC Support
T his AMI BIOS supports Version 1.03 of the EPA Green PC specification.
APM Support
T his 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 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 pow er manag ement and
device con figuration capabilities as defined in the ACPI specification, developed by
Microso ft, Intel and T oshiba.

PCI Bus Support
T his AMI BIOS also supports Version 2.3 of the Intel PCI (Peripheral Component
Interconn ect) local bus speci fication.
DRAM S upport
DDR3 SDRAM (Double Data Rate III Synchronous DRAM) is supported.
Supported CP Us
T his AMI BIOS supports the AMD 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
