drive bay, you must also install an expansion card with an IDE
controller and data cable (not supplied) because the secondary IDE
controller supports only two drives.
6. Connect the drive power 1 and signal 2 cables and, if it is an
optical drive and if analog audio is preferred to digital audio,
connect the audio cable 3. The other end of the audio cable
should be connected to the embedded audio connector on the
system board.
