Format of VESA EDID record:
Offset	Size	Description	)
 00h  8 BYTEs	padding (all FFh, or 00h FFh..FFh 00h)
 08h	WORD	big-endian manufacturer ID (see #00136)
		bits 14-10: first letter (01h='A', 02h='B', etc.)

 0Ah	WORD	EDID ID code -- identifies monitor model
 0Ch	DWORD	serial number or FFFFFFFFh
		for "MAG", subtract 7000000 to get actual serial number
