Hi Dave
Do remember, it doesn't have any openboot either.
The value at 07F9 is what one would expect to see
on an uninitialize clock or stopped clock.

I pulled the NVRAM from my Sparcbook S1 to read
it.
I looked at the data and it doesn't look like anything was
stored in it.
The first 8 bytes are FF then it is 00 until 0407.
It then turns to FF until 07F9 that is 80. It is
then FF until the end.
According to the spec sheet, the 80 would indicate
that the clock oscillator is turn off.
I wanted to make sure I'd not accidentally damaged
some byte in it so I put it back into my Sparcbook.
It booted fine with only the message that the clock
needed resetting ( always there but I've not attempted
to set it ).
Is it possible that it is storing everything on the disk
and not using the NVRAM for anything, only the clock function?
I suppose it's possible but it'd be extremely non-Sun-like. Your
Ethernet MAC address should be in there; is it coming up with a useful
one, or all 0xFF?
