Standard IDE Disk Drive Configuration

System Cabling
Your system is cabled using the on-board dual enhanced
IDE controller. This controller has two connectors
(primary and secondary) on the system board, each
connector supporting a first (master) and a second
(slave) device. This provides support for the internally
mounted CD-ROM, an optional tape, and up to three
internally mounted hard disk drives. Figure A-1 is a
diagram of the standard cabling and Figure A-2
illustrates the internal cable routing for this
configuration.
A three-connector IDE cable (Figure A-1, K) connects
the primary IDE connector on the top edge of the
system board (Figure A-1, O) to the first hard drive
(HD0) as its master device (Figure A-1, J) and the CD-
ROM as its slave device (Figure A-1, I). Another three-
connector IDE cable (Figure A-1, H) connects the
secondary IDE connector on the top edge of the system
board (Figure A-1, P) to the optional second hard drive
as its master device (Figure A-1, G) and the optional
third hard drive (HD2) or optional tape drive as its
slave device (Figure A-1, F).
As an option, the on-board Adaptec 7880 wide SCSI
controller can be used to control a SCSI tape drive. In
this case, a two-connector SCSI cable (Figure A-1, D)
connects the wide SCSI connector on the top edge of the
system board (Figure A-1, E) to the optional SCSI tape
drive (Figure A-1, B) via a narrow SCSI to wide SCSI
adapter (Figure A-1, C). The tape drive SCSI address
assignment is 2. SCSI termination must be installed in
the last SCSI drive of the daisy chain cabling. Since the
tape is your only SCSI device, the termination resistors
(Figure A-1, A) are installed in the tape drive.
When adding or removing IDE devices, consider the
following:
The system board supports a primary and secondary
IDE channel connector. Each of these supports two
devices, for a total of four IDE devices.
