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-Output System (BIOS) determines what a computer c an do without
accessing programs from a disk. This system controls most of the input and
outp ut devices suc h as keybo ard, mouse, serial po rts 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.
