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. Non-fatal error messages usually
appear on the screen along with the following instructions:
press <F1> to RESUME
Write down the message, and press the F1 key to continue the bootup
sequence.
These routines check the current system configuration against the
values stored in the card's 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 CMOS 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 informa-
tion has been erased.
The mainboard CMOS memory has an integral lithium battery backup.
The battery backup should last ten years in normal service, but when it
finally runs down, you will need to replace the complete unit.
