Appendix A
BIOS Error Beep 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 with bootup. The error messages normally appear on the screen.
Fatal errors
will not allow the system to continue to boot up. If a fa-
tal 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 correspond to the number of
beeps for the corresponding error.
Connect an external speaker to hear the beep codes.
