Serial ATA hard drives should be connected to the connectors labeled "SATA0," SATA1," "SATA2," or "SATA3" on the system board. IDE Drive Addressing 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 the master or boot device (drive 0), and the device attached to the middle connector on the interface cable is the slave 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.
