Hi Rudolf, Jean

Thank you for your reply.

I will try the commands you gave me after a while, because the PC with
that motherboard is under Windows now. after my test, then I will send you
the output message in another mail.

Our 792 Windows driver can NOT work on this motherboard either, one of
my colleague is debugging it under Windows, and we also will contact ASUS
with the questions you provided, then forward you the answer.

Thanks
Best Regards
Chunhao
