Does this document (also) describe FreeBSD SCSI?

FreeBSD and DEC UNIX/Tru64 have both implemented the ANSI CAM spec.

Thus the reason that DEC's implementation looks a lot like the FreeBSD SCSI
layer.  (They're based on the same spec.)

The spec is here:

So the DEC CAM paper may be somewhat applicable to FreeBSD, but certainly not
100% applicable.
