3.1 System Test and Initialization
The system uses certain routines to perform testing and initialization during the boot
up sequence. If an error, fatal or non-fatal, is encountered, the system will output a few
short beeps or an error message. The board can usually continue the boot up
sequence with non-fatal errors.
The system configuration verification routines check the current system configuration
against the values stored in the CMOS memory. If they do not match, an error message
will be output, and the BIOS setup program will need to be run to set the configuration
information in memory.
There are three situations in which the CMOS settings will need to be set or changed:
- Starting the system for the first time
- The system hardware has been changed
- The CMOS memory has lost power and the configuration information is erased
The system’s CMOS memory uses a backup battery for data retention. The battery
must be replaced when it runs down.
