The FM Radio Extension is installed by the TV/FM Software v1.5.3 (or 1.5.4) which comes with the TV/FM Tuner card. Allows you to listen to FM radio on your Mac. There is no reason that this software should be installed on a PowerBook computer since the TV/FM Tuner card cannot be installed in a PowerBook computer. Note: The Extensions Manager (accessed by holding down space bar at startup) will not recognize the FM Radio Extension, so you must start up with the Shift key held down which turns off all extensions.
