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 display an error message. The system 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 and BIOS NVRAM. If a system
configuration is not found or an error is detected, the system will load the default
configuration and reboot automatically.
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 system configuration was reset by the Clear CMOS jumper
- 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.
