5. Connect the IDE, power, and audio cables on the back of the optical drive.
NOTE: The system has two IDE cables — one is marked "Hard Drives," the other is marked
"Optical Devices." Make sure you connect them properly. The black connector on each cable is
for the master device; the gray connector is for the slave device. Make sure the jumper on the
optical drive is set to cable select (CSEL), not to master (M) or slave (S). See the documentation
provided with your drive for help locating the jumper.
6. Replace the covers and reconnect all cables.
7. Turn the system on, then execute the EFI shell info io command to verify that the optical
drive has been properly installed. For more information on EFI, see Chapter 3.
