Single instance.

Will this depend on how we do the binding for each card or the
way
we install the card??

NT4 way:

  • the binding engine creates a registry entry for each card hanging off your
    driver
  • the driver calls NdisMRegisterMiniport when loaded
  • this function enumerates the registry list of cards and calls the callback
    in your miniport for each card, passing its hardware “coordinates” there.

w2k uses a bit different way - its cards are enumerated by means of PnP.
