I have six of those Emulex cards you speak of.  NetBSD had to be hacked?  It
didn't just fall back if a 10-byte command was rejected repeatedly?  (That
should be a per-target configurable anyway, but....)  Hrm.  That card worked
on my Amiga under NetBSD/amiga at the time (1.0A or so).

Incidentally, I _like_ these cards.  Not only do they let me use old, free
hardware, but they also map two ESDI drives to one SCSI unit (using LUNs).
