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).
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 mother 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 mother board.
