When To Reconfigure The Workstation; Using The Cable-Select Feature With Ultra Ata Devices - Compaq Deskpro Workstation AP240 Reference Manual

When to
Reconfigure the
Workstation
Using the Cable-
Select Feature with
Ultra ATA Devices
System configuration is the process of specifying the devices
and programs that make up a workstation system. When you
add or remove optional equipment, the workstation must be
reconfigured to recognize these changes. To reconfigure the
workstation in Windows NT version 4.0, use the software
utility provided with the newly installed hardware.
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 workstation
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-pin 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-pin conductor Ultra ATA cable for
optimal performance. This cable is standard on select
models and is also available as a Compaq option.
