I'm attempting to use a 3Com 3C503 card in a PC-XT with SUN PC-NFS.  There
was a Western Digital card in there which worked fine, but now with the
3C503, the thing dies when it attempts to run PC-NFS.  My guess is that
there may be a conflict with DMA channels since the 3C503 uses DMA and
the WD does not, however I can't figure out how to disable use of DMA
on either the hardware or software.  Anybody know this answer?

Thanks in advance.
