BIOS Setup
Introduction
The purpose of this manual is to describe the settings in the Phoenix-Award™
BIOS Setup program on this motherboard. The Setup program allows users to
mod ify the bas ic system configuratio n and save these s ettings to CMOS RAM.
The power of CMOS RAM is supplied by a battery so that it retains the Setup
information when the po wer 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 suc h as keybo ard, mouse, s erial ports and disk drives. BIOS
activates at the first stage o f the boo ting process, lo ad ing 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.
