;
;	This file contains the Command Tables that actually
;	drives the SCSI Driver when talking to a target
;	device.  By changing these tables, the SCSI Driver
;	will be able to talk to almost any class of SCSI
;	Device.  There are actually two tables in this file.
;	The first table is a list of a two word group for
;	each command supported.
;
;	The first word is the actual SCSI Command Number
;	followed by the low word of that commands table
;	address.  We use the only the low word because the
;	second table is in the same bank as the indexing
;	table.
;
;	The second table is the actual command translation
;	data.  The first word is a set of flags that
;	indicate some of the translation and verification
;	that needs to take place.
;
;		Bit	15	=	Data is being sent to the device
;			14	=	Data is to be received by us
;			13	=	This is a Status Command
;			12	=	This is a Control Command
;			11	=	Data I/O Command
;			10	=	Device I/O Command
;			 9	=	Command Includes Block Number
;			 8	=	Must be first device if linked
;			 7	=	Internal Driver Command Only
;			 6	=	Must issue a DISK_SW with this call
;			 5	=	Results in device offline
;			 4	=	Reserved
;			 3	=	Command Data needs no translation
;			 2	=	Reserved
;			 1	=	Block request count goes into command
;			 0	=	Byte request count goes into command
;
;	The second word is a time out tick count to be used by
;	the SCSI Manager to determine when to abandone any SCSI
;	Device transaction due to lack of response by the
;	target.  Each tick = 250 ms.
;
;	Any additional words are only used if Bit 3 above is
;	zero.  The translation bytes conatin two offsets.  A
;	Source and a Destination offset.  This is used by the
;	driver to take information fron the caller's command
;	(Source) and .OR. them in to their proper location in
;	the SCSI Command Packet (Destination).

;	The next byte is the offset to the first and most

;	The byte following this is the number of bytes that
