Make sure you get the Intelligent card though. The Interlan NI5210 (which is
a "dumb" card) does NOT work with NFS; we've tried and tried, and always
met with failure. We haven't tried the intelligent card (as John evidently
has, with much success); all I can say is that the NI5210 don't work.
Interactive have confirmed this as follows:

% There are known problems running NFS with that particular

% In sum, we suggest any other card than the NI5210.
