I have tested a RICOH PCMCIA to PCI Adapter card. The PCMCIA to PCI Adapter card was tested using different operating systems (Win2000,XP,98,95) and using a Micron computer PIII 650 processor. When testing under the XP environment, with service pack 1, NI's device drivers Version 1.7 failed to load. (Code 10) Ni's driver version 1.7 was then removed and NI's device driver Version 2.2 was loaded. I did not experience any commutation problem as long as I used the standard NI calls. I did experience a problem with NI’s IBDIAG function call which is not supported under Version 2.2.
I would recommend that you get the latest service pack for XP and NI’s device driver Version 2.2.
