B appendix HARD DRIVE INSTALLATION Using the Cable-Select Feature with Ultra ATA Devices Select models of the Compaq Deskpro Workstation 300 have an internal IDE Ultra ATA hard drive preinstalled. 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. 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. Compaq Deskpro Workstation 300 Hardware Reference Guide B-1

Using the Cable-Select Feature with Ultra ATA Devices
Select models of the Compaq Deskpro Workstation 300 have an
internal IDE Ultra ATA hard drive preinstalled. 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.
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.
