Hi Michael,

It  seems  they  fuck  up  all bioses, and there response is that they
don't  support  anything  other than microsoft stuff. And are not very
sensitive to the fact that it doesn't adhere to the intel vt-d specs.

Commenting  out  a  check on the RMRR address having an "end address >
start address" helps.
But i don't have this problem in xen-unstable anymore, so i think the
check has been relaxt there.

Sander,

I just built xen-unstable from source and gave it a go, but I get pretty much the same output and still no VT-d. Not being particularly familiar with the code in question, what's the best way to try and comment out the check completely?

Also, what Windows based virtualization software supports VT-d? Something so I can try leveraging Asus into actually fixing this problem.

Cheers,
Mike
