Gag.  ATI X200 chipset or similar?  That one seems to be pervasive in
the name-brand sector for some reason.  Yes, I have seen those
complaints before.  I think this is a hardware issue.  Or at least an
issue of the software and hardware not agreeing on something.

PCI-X?  Then this is a server class board and different from my
desktop class nForce4.  I guess I can't help you much, then.

There's no telling, I guess.  There is likely an issue in some driver
somewhere.  It's mostly the same code, as far as I know.  It seems
software will never be perfect, and when it comes to interacting with
hardware, things get even more interesting.
