appendix C HARD DRIVE INSTALLATION GUIDELINES Using the Cable-Select Feature with Ultra ATA Devices Optional drives are available from Compaq in kits that include a special drive cable. The configuration of the drives employs a cable-select feature that identifies the drives as device 0 (primary drive) or device 1 (secondary drive). The computer recognizes device 0 as the drive connected to the short segment of the drive cable (farthest from the system board), and device 1 as the drive connected to the long segment of the drive cable (closest to the system board). When using an 80 conductor Ultra ATA cable, connect the colored connectors as follows:  blue-system board (end)  gray-device 1 (middle)  black-device 0 (end) Drive installation requires no jumper setting changes on the existing or optional drives. All Compaq drives have the jumpers preset for cable- select installation. If installing a second device on the primary controller, you must use an 80 conductor Ultra ATA cable for optimal performance. This cable is standard on select models. Hardware Reference Guide C-1

Using the Cable-Select Feature with Ultra ATA Devices
Optional drives are available from Compaq in kits that include a special
drive cable. The configuration of the drives employs a cable-select
feature that identifies the drives as device 0 (primary drive) or device 1
(secondary drive). The computer recognizes device 0 as the drive
connected to the short segment of the drive cable (farthest from the
system board), and device 1 as the drive connected to the long segment
of the drive cable (closest to the system board).
When using an 80 conductor Ultra ATA cable, connect the colored
connectors as follows:
blue–system board (end)
gray–device 1 (middle)
black–device 0 (end)
Drive installation requires no jumper setting changes on the existing or
optional drives. All Compaq drives have the jumpers preset for cable-
select installation.
If installing a second device on the primary controller, you
must use an 80 conductor Ultra ATA cable for optimal
performance. This cable is standard on select models.
