The 14F is a busmastering card that uses DMA for data
transfer.  The 14N is a PIO card that used the same 
chipset. It only seems to have DOS drivers for it from
Ultrastor (no NT/OS2/*ix).

Not that I know of.

Don't know how Ultrastor is as far as giving out programming
info. The 14N was a low-end card that seemed to be orphaned 
as soon as it hit the market.  The target market (low-end 
SCSI cards) is just brutal, and not very profitable.
