It's a WDM driver and HalGetBusData is deprecated in 2000 and above. The
next question he's going to ask is why slot number in an XYZ motherboard is
not the same as the slot number on an ABC motherboard. Slot number in WDM
drivers is not needed since you get your resources in IRP_MN_START_DEVICE.
Typical bad assumptions assosicated with this is that the number by the PCI
adapter is not the same as the number assigned by the BIOS. Slot number is
an archaic hold over from NT4.
