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 information is stored in a
battery-backed memory (CMOS RAM) so that it retains the setup infor-
mation 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 the system operates in harsh industrial envi-
ronment and causes a soft error, BIOS will recheck the data in CMOS
RAM and automatically restore the original data in Flash ROM to CMOS
RAM for booting.
Note:
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 is supported on your
CPU. If there is no number assigned to the patch code, please contact an
Advantech 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.
ARK-5280 User Manual
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 check sum
error..." message appears again and again,
please check to see if you need to replace the
battery in your system.
