The following codes are not displayed on the screen. They can only be
viewed on the LED display of a so called POST card. The codes are listened
in the same order as the according functions are executed at PC startup. If
you have access to a POST Card reader, you can watch the system perform
each test by the value that's displayed. If the system hangs (if there's a
problem) the last value displayed will give you a good idea where and what
went wrong, or what's bad on the system board.
