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. 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
boot-up sequence.
System configuration verification
These routines check the current system configuration against the
values stored in the card’s CMOS memory. If they don’t 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 SBC-556/L
,
s 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.
