External SCSI Hard Disks
The documentation that comes with your external SCSI (Small Com-
puter System Interface) hard disk should contain all of the necessary
information for connecting and configuring the disk.
Identifying Hard Disks
Hard disks are identified by device numbers which you assign. Valid
choices for external SCSI hard disks range from DSK0 to DSK6.
However, you cannot repeat numbers; each device number must be
unique. The internal IDE hard disk is identified as DSK7.
