     Note: LW and LC drives do not have internal terminators or
           any other way of adding internal terminators to the
           drive; use external active termination if required.
           Use active (ANSI SCSI-2 Alternative 2) terminators
           when terminating the bus.  Use active negation
           terminators when terminating a SCSI Ultra2 bus
           operating in Low Voltage Differential (LVD) mode.
