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 environment
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.
Note: If you intend to change the CMOS setting without 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..."message appears again and again, please check to see if you
need to replace the battery in your system.
4.2 Entering Setup
Turn on the computer and check for the "patch code". If there is a number
assigned to the patch code, it means that the BIOS support your CPU. If
there is no number assigned to the patch code, please contact Advantech's
applications engineer to obtain an up-to-date patch code file. This will
ensure that your CPU's system status is valid. After ensuring that you
have a number assigned to the patch code, press <Del> to allow you to
enter the setup
