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. The 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. BIOS activates at the first stag e o f the booting proc ess, l oading and executing the operating s ystem. S om 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 P l ay 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 speci fication.

APM Support

This AMI BIOS supports Version 1.1&1.2 of the Advanced Power Management (AP M) speci fic atio n. Power m anag ement fe atu res a re implem ented vi a the System

Management Interrupt (SMI). Sleep and Suspend power management modes are supported. P ower to the hard disk drives and video m onitors 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 management and

device configuration capabilities as defined in the ACPI specific ation, developed by Microso ft, Intel and T oshiba.
