The best way to be sure would be to check to which pin the resitor is
connected. On the datasheed I have there's a pin to which a pullup resistor
can be connected, exactly to change the PCI subclass.
Maybe win2k does the same as pciide, which is to look at product ID instead of
PCI subclass for promise (and a few others) IDE controllers ?
