Have you verified that there are no new BIOS versions available for your
motherboard? From what I can tell, when we write to registers over the
PCI bus, we are not getting the expected results. This may mean that
the PCI chipset has a non-standard caching feature enabled that violates
the PCI spec. I've seen this on some other VIA based boards.
