Well I have strong doubts that this our windows people are actually involved in this. This could be fixed our worked around by a motherboard driver, but not by the graphics driver. As I said you could try to force the PCI subsystem to reallocate the bridges or maybe try to update the BIOS, but from the graphics driver you can't do anything here. Regards, Christian.
