	Originally, Adaptec had two different 4000 type cards, the ACB-4000
was for soft sectored disks and the ACB-4010 was for hard sectored disks.
When they went to the ACB-4000A, they simply implemented both options on
the same card. they also did some firmware changes that allowed for a little
more compatibility with the full SCSI Common Command Set.
