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

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.

Bas ic Input-Outp ut Sys tem (BIOS) determines what a co mputer c an do without

accessing programs from a disk. This system controls most of the input and

outp ut d evices suc h as keybo ard, mouse, serial ports and d isk drives. BIOS

activates at the first stage of the 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.
