Erik, do you have any of the documentation for the Ultrabook?
Attached are the NVRAM settings for the Ultrabook found in the
"Ultrabook Hardware Reference Guide". Also attached is an NVRAM recovery
procedure that Sun put out on the Ultrabook.

Yeah - reading the source code of QEMU I found the

EVEN BETTER there was a WEB page with a good description of the various
NVRAMs on Sun machines up to Ultra1. Yes, there "was".
FORTUNATELY via archive.org, that page can be accessed - Tadaaaaaaaa-
here it is:

HOT: As I suspected: The first byte of the hostID in some systems defines
the machine type.
PERFECT: There are also commands given to read/write the NVRAM from the
firmware.
Thanks Ethan, the hint to check the emulation was great!
