Hard Drive Installation Guidelines
Optional drives are available from Compaq in kits that include a
special drive cable. The configuration of the drive employs a
cable-select feature that identifies the drive as device 0 (master drive)
or device 1 (slave drive).
Device 1 is the drive connected to the cable's middle connector.
Device 0 is the drive connected to the cable's end connector (applies
only to 80-conductor ATA cables). See "Guidelines for Installing
Ultra ATA Devices" in this appendix for an example of an
Ultra ATA cable.
Compaq hard drives ship with jumpers preset to cable-select mode;
therefore, no jumper setting changes on the existing or optional drives
are required. If you purchase a third-party hard drive, refer to the
documentation included with the kit to ensure proper installation and
configuration of cables.
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.
