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 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 stage o f the booting process, l oading and executing t he operating system. S ome
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 AM I BIOS supports the Plug and Play Version 1. 0A specific ation.
EPA Green PC Support
T his AM I BIOS supports Version 1.03 of t he 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 an agement fe atures a re implement ed vi a the Syst em
Management Interrupt (SMI). Sleep and Suspend power management modes are
supported. Power to the hard disk drives and video m onitors 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 m anagement and
device con figuration capabilities as defined in the ACPI specification, developed by
Microsoft, Intel and T oshiba.
