System test and initialization
These routines test and initialize board hardware. If the routines
encounter an error in 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.
If the routines encounter a fatal error, they will stop the tests and
output a message indicating which test failed. If the fatal error
comes before the screen device initializes, the card will indicate
the error code through a series of beeps.
You can also determine the number of the test that failed by
reading the LED indicators on the top of the PCA-6157 board. See
Appendix B for details.
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.
