(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.
sense code for zero and if found repeat the request sense. This solves
a bug in the sbic driver when accessing JAZ drives that results in
faulty sense data being returned following a transfer. A retry returns
the correct information.
This is probably showing up a more fundemental bug in the sbic driver
and will probably have to wait for a complete overhaul of the sbic
driver (planned) for a perfect fix.
