Chapter 3 Award BIOS Setup 3.1 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.
3.1.1 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.
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.
