General Installation Guidelines
Connect CD/DVD drives to the connector labeled "IDE" on the system board. Serial ATA hard drives should be connected to the connectors labeled "SATA0" or
"SATA2" on the system board.

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.

Drive Interface Connectors
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. Keyed connectors ensure that the pin-1 wire in the cable goes to the pin-1 end of the connector. The pin-1 end of a connector on a board or a card
is usually indicated by a silk-screened "1" printed directly on the board or card.
