SCSI documentation

[Kenneth Porter]

I'd like to hack some SCSI stuff, probably at the device driver level.  I
have the standard Sun/Unix device driver book, but I'd like to know what
SCSI documentation is available.

My work will probably initially be on a 386i, but I'd like to get a more
generic answer so that I can see how SCSI works across different
architectures.  (I may eventually get a Sparc and need to port.)
