BIOS POST Codes
This section lists the POST (Power On Self-Test) codes for the Phoenix BIOS. POST
codes are divided into two categories: recoverable and terminal.
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 correspond to the number of beeps for the corresponding
error.
BIOS POST-Codes (Port 80 status indicators)
BIOS-POST codes are visible on the LCD-display (connected to the LCD-connector).
