Abstract
A computer system includes a chassis, a processor mounted in the chassis, a memory coupled to the processor, and an optical disc drive coupled to the processor and the memory, the optical disc drive comprising a removable storage media, the optical disc drive being configurable to internally generate an audio tone signal in response to receiving a command during an absence of the removable storage media; to receive a second command, wherein the second command generates a corresponding second audio tone signal and to receive a third command, and wherein the third command is configurable to stop the generation of the second audio tone signal.
