[comp.sys.amiga.hardware] SCSI Direct Driver

	Hi all, 

	I am still trying to get my Archive Tape drive working with
my Amiga 2000. Every SCSI board vendor (I have a CLTD Kronos, but am
looking for a board that will directly work with the ARCHIVE) tells
me I need to write a driver for the archive. Now, I want to use BTN
to access the drive, but I am assuming I still need a driver...
The BTN handler uses SCSI direct protocol to access the Tape Drive,
and my C.Ltd controller does support SCSI Direct, now what kind of
driver do I need to write? Low Level routines to talk directly to the
Drive? I am missing some part of the modularity here I know, but I am
just confused!......The is a HardDisk.driver, and CLTD.device in the
DEVS directory, and SCSI-Link.Library in my LIBS: directory. Shouldn't
these drivers/libraries support SCSI direct (as the controller does?)

The C LTD software does NOT support SCSI DIRECT.  They came up with 
their own generic_scsi idea, supported by the scsi-link.library; 
I don't know whether it works.  

To try any of this out you will have to rewrite BTN or other client
to use the scsi-link calls rather than scsi_direct calls.  If your
distribution of scsi-link has a stub library and include files, you
can probably generate a program.  You will still be relying on the
code in scsi-link.library; since almost no one used it, it wasn't
very well field tested.
