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 bootup. If a fatal error oc-
curs, 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.
