National Instruments does make an NI-488.2 DDK. This is source code for a
subset of the NI-488.2 driver. One of the examples that it ships with is a
driver for the PCI-GPIB board under DOS. Since this driver is a subset of
the NI-488.2 API (it only supports board-level calls), you may need to make
some modifications to your program, but it should be fairly straightforward.
Contact National Instruments sales for more information.
