This question amounts to: “How do I write a device driver for Windows 2000?
How do I write a device driver for Windows NT V4.0?”
Because Win2K supports PnP, and NT V4 doesn’t, the design of the two are
fundamentally different.
In NT V4, you search the PCI Bus, calling HalGetBusData(), until you find
your device. You then call HalAssignSlotResources() to get the resources
assigned to your PCI card.
In Win2K, you write a PnP-enabled device driver. You specify your VID, DID,
SubSystem ID, and Rev in an INF file. The PnP Manager calls you at your
AddDevice() entry point to tell you your device was discovered.
There’s enough involved that you could write a whole book about this.
Hmmmm, now THERE an idea.
