ECMA
VERSION
(Byte 2, Bits 5-3) - Set to zero to indicate that the ProDrive does not
claim compliance to the European Computer Manufacturers Association version
of
SCSI.
ANSI
VERSION
(Byte 2, Bits 2-0) - Set to one to indicate compliance with the ANSI
specification for SCSI.
RESPONSE
DATA
FORMAT
(Byte
3,
Bits 3-0) - Set to one to indicate compliance with
the Common Command Set proposed by an ANSC X3T9.2 working group.
ADDITIONAL

LENGTH
(Byte 4) - Specifies the length in bytes
of
the list
of
drive
identification information. The
ProDrive identification information is shown
on
the following
chart.
If
the allocation length
of
the command descriptor block is too small to transfer all
of
the
vendor unique parameters, the additional length value will not be adjusted to reflect the truncation.
