Chapter 2
This chapter tells how to change the system settings through the BIOS
Setup menus. Detailed descriptions of the BIOS parameters are also pro-
vided.
2.1 Introduction
Award's BIOS ROM has a built-in setup program that allows users to
modify the basic system configuration. This type of information is stored
in battery backed-up memory (CMOS RAM) so that it retains the setup
information when the power is turned off.
2.1.1
CMOS RAM Auto-backup and Restore
The CMOS RAM is powered by an onboard button cell battery. When
you finish BIOS setup, the data in CMOS RAM will be automatically
backed up to Flash ROM. If operation in harsh industrial environments
causes a soft error, BIOS will recheck the data in CMOS RAM and auto-
matically restore the original data in Flash ROM to CMOS RAM for
booting.
Notes
If you intend to change the CMOS setting with-out restoring the previous
backup, you have to click on "DEL" within two seconds of the "CMOS
checksum error..." display screen message appearing. Then enter the
"Setup" screen to modify the data. If the "CMOS checksum error..." mes-
sage appears again and again, please check to see if you need to replace
the battery in your system.
