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 ofCMOS
RAM is supplied by abattery so that it retains theSetup informationwhen 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 stage ofthe booting process, loading and executing the operating system. Some
additional features, such as virus and password protection 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.
