OK, I've used flashrom/biossavior on a Tyan box to get the *actual* contents
of the chip (I hope!).

This one is 3 bytes different from the q-flash image (or any of the flashrom
images made on the gigabyte board itself):

I didn't notice that change in 0000fd94 in the previous diffs, so it's
basically the same phenomenon as with flashrom on the gigabyte machine itself
- 3 bytes change between boots.

So.... are flashrom and Q-flash doing the right thing (disabling shadowing),
and if so, what's causing those 3 bytes to be different each time?

Thanks,
Ward.
