If more than one Apple CD-ROM device is used on a Macintosh computer, the
device with the lowest SCSI number is the unit that CD Remote will control. As
an example, two CD-ROM devices are on the SCSI bus. One has a SCSI ID of 2 and
the other has an SCSI ID of 5. The CD-ROM device with the SCSI ID of 2 will be
the unit accessed by CD Remote. There is no way to change this.
