8. Beep
Codes
During the course of executing POST, there are occassions where fatal problems happen
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.

Memory Test Failure
8.1.1.1
No Memory Found in the System
This indicates that the memory test has found no valid memory in the system. The system will
not boot. An SEL log entry will be made in this case.

This indicates that only a single row is populated, and that row contains mismatched DIMMs,
preventing booting. An SEL log entry will be made in this case.
