3.1 System Test and Initialization
The system uses certain routines to perform testing and initialization. If an error, fatal
or non-fatal, is encountered, a few short beeps or an error message will be outputted.
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 outputted, in which case you will need to run the BIOS setup program
to set the configuration information in memory.
There are three situations in which you will need to change the CMOS settings:
- You are starting your system for the first time
- You have changed your system’s hardware
- The CMOS memory has lost power and the configuration information is erased
The system’s CMOS memory uses a backup battery for data retention, which is to be
replaced once emptied.
