Dell XPS/Dimension XPS Gen 4 - Manual (Page 29)

General Installation Guidelines
Connect serial ATA hard drives and serial CD/DVD drives to the system board connectors labeled SATA-0, SATA-1, SATA-2, or SATA-3. Connect IDE CD/DVD
drives to the connector labeled PRI IDE.
When you connect two IDE devices to a single IDE interface cable and configure them for the cable select setting, the device attached to the last connector on
the interface cable is primary or the boot device (drive 0), and the device attached to the middle connector on the interface cable is the secondary device
(drive 1). See the drive documentation in your upgrade kit for information on configuring devices for the cable select setting.
Connecting Drive Cables
When you install a drive, you connect two cables—a DC power cable and a data cable—to the back of the drive and to the system board. Some drives may
also have an audio connector; one end of the audio cable will attach to the drive connector and the other will attach to the system board.
Drive Interface Connectors
Serial ATA Connector
Most interface connectors are keyed for correct insertion; that is, a notch or a missing pin on one connector matches a tab or a filled-in hole on the other
connector.
When connecting an IDE cable, ensure that you align the colored stripe with the pin 1 connector. When disconnecting an IDE cable, grasp the colored pull-tab
and pull until the connector detaches.
When connecting and disconnecting a serial ATA cable, hold the cable by the connector at each end.
NOTE: The system board serial ATA connector may have an attached cover or shroud.
