I am not sure I understand your question, and it appears you have already been talking to someone about this issue. If so you may want to direct these questions back to them.
However it appears that you have a third party GPIB card and you are wondering if NIs GPIB driver will work with it. If that is the case then the answer is no. NIs 488.2 driver is for our GPIB boards only.
We do provide instrument drivers, but those are actually a collection of VIs to control an instrument, not a board.
If I have misunderstood your question let me know.
