3.1 System Test and Initialization
These routines test and initialize board hardware. If the routines encounter an error
during the tests, you will either hear a few short beeps or see an error message on the
screen. There are two kinds of errors: fatal and non-fatal. The system can usually
continue the boot up sequence with non-fatal errors.
System configuration verification
These routines check the current system configuration stored in the CMOS memory
and BIOS NVRAM. If system configuration is not found or system configuration data
error is detected, system will load optimized default and re-boot with this default
system configuration automatically.
There are four situations in which you will need to setup system configuration:
1. You are starting your system for the first time
2. You have changed the hardware attached to your system
3. The system configuration is reset by Clear-CMOS jumper
4. The CMOS memory has lost power and the configuration information has been
erased.
The COM-BT-A30 CMOS memory has an integral lithium battery backup for data
retention. However, you will need to replace the complete unit when it finally runs
down.
