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 manufac-
turer for possible repairs.
These fatal errors are usually communicated through a series of audible beeps.
The numbers on the fatal error list correspond to the number of beeps for the
corresponding error.
