10. Beep Codes

During the course of executing POST, there are occasions where fatal problems may occur
before video is enabled. These fatal errors are conveyed with the use of the speaker via
Encoded beeps, coupled with post debug codes.
Since the duration of the display-less POST execution is relatively short, there are fewer beep
codes than displayed error codes.
In order to extend the useful range of the beep codes, without the need to have dozens of
codes, the beeps are classified and the distinction within class is made via the post debug card.
Bolded and italicized items are not used on SR870BH2 BIOS.
