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 against the
values stored in the CMOS memory. If they do not match, the program
outputs an error message. You will then 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:
1. You are starting your system for the first time
2. You have changed the hardware attached to your system
3. The CMOS memory has lost power and the configuration information
has been erased.
The EMB-H61B CMOS memory has an integral lithium battery backup
for data retention. However, you will need to replace the complete unit
when it runs down.
