:1. First of all, make sure that 3.5" external disc drive B is connected to the back of "Disc Drive" connector (located on the back of keyboard), and switched on. Then power up the computer by switching the monitor on and the keyboard on as well, the 3" and 3.5" drive lights up, ready for 2 disc drive operation.
