Chapter 7 BIOS

7-1 Introduction

This chapter describes the AwardBIOS for the P8SCT. The Award ROM BIOS
is stored in a Flash chip and can be easily upgraded using a fl oppy disk-based
program.
Note: Due to periodic changes to the BIOS, some settings may have been added
or deleted and might not yet be recorded in this manual. Refer to the Manual
Download area of our web site for any changes to the BIOS that are not refl ected
in this manual.

System BIOS

The BIOS is the Basic Input Output System used in all IBM® PC, XT™, AT®, and
PS/2® compatible computers. The AwardBIOS Flash chip stores the system pa-
rameters, such as amount of memory, type of disk drives and video displays, etc.
CMOS requires very little power. When the computer is turned off, a back-up battery
provides power to the BIOS Flash chip, enabling it to retain the system parameters.
Each time the computer is powered-on, the computer is then confi gured with the
values stored in the BIOS ROM by the system BIOS, which gains control when the
computer is powered on.

How To Change the Confi guration Data

The CMOS information that determines the system parameters may be changed
by entering the BIOS Setup utility. This Setup utility can be accessed by pressing
<Del> at the appropriate time during system boot.

Starting the Setup Utility

Normally, the only visible POST (Power On Self Test) routine is the memory test. As
the memory is being tested, press the <Delete> key to enter the main menu of the
BIOS Setup utility. From the main menu, you can access the other setup screens,
such as the Chipset and Power menus. Section 7-3 gives detailed descriptions of
each parameter setting in the Setup utility.
