Introduction
This chapter describes the AwardBIOS for the P4SCT+. The Award ROM BIOS
is stored in a Flash chip and can be easily upgraded using a floppy 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 BIOS that are not reflected in
this manual.
System BIOS
The BIOS is the Basic Input Output System used in all IBM
®
PS/2
compatible computers. The AwardBIOS Flash chip stores the system
parameters, 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 con-
figured 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 Configuration 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 press-
ing <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 4-3 gives detailed
descriptions of each parameter setting in the Setup utility.
