BIOS Error POST (Beep) Codes
During the POST (Power-On Self-Test) routines, which are performed upon each system
boot, errors may occur.
Non-fatal errors are those which, in most cases, allow the system to continue to boot. These
error messages normally appear on the screen.
Fatal errors will not allow the system to continue with bootup. 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 correspond to the number of beeps for the corresponding error.
