When it fails to display, the error is before video testing :-)

Which means the video card's ****ed.

The beep error codes, include a RAM error beep code.

This allows telling you the system RAM is bad, without
requiring anything other than that motherboard piezo.

The beep pattern is "coded", so more than one error
indication can be delivered to the user.
