I had put out a notice to get some feedback about SCSI controllers, and I've
been getting rather contradictory replies.  Most have said that they've
experienced almost no incompatibilities, with a few exceptions.  However, 
I've also gotten mail telling me not to get it because it uses PIO.  First,
does PIO mean Programmed IO?  Second, why is it disadvantageous for a HD/FD
controller to use PIO?

Any help would be appreciated.

Thanks,
