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. 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.
If you think you may have installed this extension and your PowerBook computer is now crashing while starting up, follow these steps:
1. Restart the computer with the Shift key held down*.
2. After the computer has started up, open the System Folder
3. Open the Extensions folder
4. Remove the "FM Radio Extension" from the Extensions folder.
5. Restart the computer. The PowerBook will restart normally after removing the extension.
* Note: The Extensions Manager (accessed by holding down space bar at startup) will not recognize the FM Radio Extension,sSo you must start up with the Shift key held down which turns off all extensions.
