Compaq Computer Corporation uses IDE/EIDE hard disk drives that conform to two different
primary/secondary implementations. These are Conner mode and ATA-compatible mode. These two
modes are incompatible with one another.
Device 0/Device 1 Relationship
A device 0/device 1 relationship exists when there are two hard drives connected to a single port. In
this situation, one drive must be designated as the device 0 (primary) drive and the other as the device
1 (secondary) drive. This designation is necessary because both drives cannot work simultaneously.
Cable Select
The Compaq Deskpro 2000 Series of Personal Computers use cable-select technology for identifying
Device 0 (primary) and Device 1 (secondary) IDE/EIDE hard drives. Check that the jumpers on the
IDE/EIDE hard drives are set properly for cable-select installation. Always check the label on the
drives or check Chapter 7 of this manual when a new drive is added to verify that the jumper settings
are set correctly.
Cable select may not function properly if drives other than those supported by Compaq are
installed.
The second drive on a cable-select cable can be a CD-ROM drive. However, the CD-ROM drive
must be installed in the device 1 position if a hard drive is installed on the same cable. Ensure that
both drives are set for cable-select configuration. See Chapter 7 for more information.
If two drives are already connected to the primary IDE/EIDE controller and an additional drive is
to be installed, the secondary IDE/EIDE controller must be enabled. The secondary IDE/EIDE
controller can be enabled by checking this option after opening the Advanced box in the Mass
Storage group of F10 Computer Setup. See Chapter 2 for more information.
When more than two drives are installed, drive performances are best when the two faster drives
are connected to the primary IDE/EIDE controller and the slower drive is connected to the
secondary IDE/EIDE controller.
A hard drive is installed and configured more quickly when the jumpers have been configured
first.
If the new drive includes the cable-select feature, no jumper setting changes are required. Refer to
the documentation supplied with the drive for instructions on using the cable select feature. If you
install a third-party hard drive, you will need to purchase a jumper cable (spare part number
247568-001) from Compaq Computer Corporation.
