Using the Cable-Select Feature with Ultra ATA Devices

Compaq Evo Workstation W8000 Hardware Reference Guide
Selected models of the Evo Workstation W8000 have an internal
Ultra ATA hard drive installed. The configuration of the drive
employs a cable-select feature that identifies the drive as device 0
(primary drive) or device 1 (secondary 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 you are installing a second device on the primary controller, you
must use an 80-conductor Ultra ATA cable for optimum
performance. This cable is standard on selected models.
