A-1 BIOS Error Beep (POST) Codes
During the POST (Power-On Self-Test) routines, which are performed each time the system
is powered on, errors may occur.
Non-fatal errors
are those which, in most cases, allow the system to continue the boot-up
process. The error messages normally appear on the screen.
Fatal errors
are those which will not allow the system to continue the boot-up procedure. If
a fatal error occurs, you should consult with your system manufacturer for possible repairs.
These fatal errors are usually communicated through a series of audible beeps. The numbers
on the fatal error list (on the following page) correspond to the number of beeps for the
corresponding error. All errors listed, with the exception of Beep Code 8, are fatal errors.
