POST (Power On Self Tests)
Whenever you start up your system, the CPU card runs a series of
programs stored in an on-board ROM chip. These programs are
divided into two stages:
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
bootup sequence. Non-fatal error messages appear in Appendix F.
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. Error beep codes also
appear in Appendix F.
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.
