Real Time Clock
and CMOS RAM Setup
The system
board contains
user modifiable system configuration infor
mation
in a CMOS RAM. This power conserving RAM is battery-backed up
so
that it
retains the configuration setup information even when the computer’s
power is
switched
off. Thus, when power is switched on, configuration infor
mation
is immediately available
to the BIOS
and the operating system. The
SETUP
program
allows
the user to change the configuration information stored
in the CMOS
RAM to match
the configuration of the system.
The
BIOS
executes
the Power On Self
Test <POST> when the power
is
turned on, it will give an error message if the test results fail to match the
configuration
identified
in the CMOS
RAM. The SETUP program may then
be
used
to modify the contents of the CMOS RAM so that it matches the system
configuration.
The CMOS
RAM stores the eight bits of
information listed
below:
