Using the Cable-Select Feature with IDE Ultra

ATA Devices

Select models of the Compaq Professional Workstation AP200 have an internal IDE Ultra ATA hard drive preinstalled. Optional IDE 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 system board determines which drive is device 0 or device 1, based on the way the drives are connected to the special drive cable. The device 0 drive is the drive connected to the short segment of the drive cable (or the connector closest to the system board); the device 1 drive is the drive connected to the long segment of the drive cable.

Drive installation requires no jumper setting changes on the existing or optional drives. All Compaq drives have the jumpers preset for cable-select installation.

NOTE: If you are installing a second IDE device on the primary controller, you must use an 80-conductor IDE Ultra ATA cable for optimal performance. This cable is included with the drive option kit.

IMPORTANT: Compaq does not support mixing IDE Ultra ATA and SCSI hard drives in the same system. If you are replacing a hard drive in bay 4 or 5, it must be of the same type. If you are replacing the IDE Ultra ATA hard drive in your workstation with a SCSI hard drive, you will need a SCSI device option kit and the SCSI controller option kit. The controller option kit contains the SCSI controller and cable that supports multiple SCSI devices. See the section “Installing a SCSI Device” in this chapter.
