BIOS Setup

Introducti on

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 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, m ouse, serial ports and disk drives. B IOS activates at the
first stag e o f the booting process, l oading 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 AMI BIOS supports the P lug and Play Version 1. 0A specific ation.

EPA Green PC Support

T his AMI 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
(AP M) speci fic ation. Power m anagement fe atures a re im plement ed v ia the Syst em

Management Int errupt (SMI). Sleep and Suspend power management modes are
supported. P ower to the hard disk drives and video monitors can also be managed by

this AMI BIOS.

ACPI Supp ort

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 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
Int erconn ect ) local b u s s peci fic ati o n.

DRA M Support

Notice

z T he default BIOS settings apply for most conditions to ensure optimum per forman ce

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 M enu.
