Chapter 4 Award BIOS Setup

4.1 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 memory (CMOS RAM) so that it retains the setup
information when the power is turned off.

4.1.1 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 enviroment
cause 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.
Note:

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 mes-
sage appearing. Then enter the "Setup" screen
to modify the data. If the "CMOS checksum
error..."message appears again and again,
please check to see if you need to replace the
battery in your system.
