Terminal POST errors
There are several POST routines that issue a POST terminal error and shut down the system if they fail. Before
shutting down the system, the terminal-error handler issues a beep code signifying the test point error, writes the
error to port 80h, attempts to initialize the video, and writes the error in the upper left corner of the screen (using
both mono and color adapters).
