    Where does the Mac Startup Chime come from?

    Is it from the Mac OS X or on the Open Firmware?

    Firmware. Each Mac model has its own specific start up chime that does not change with the OS. You can even take out your hard drive, turn on your computer and still get the chime. (I don't recommend trying this unless you are already taking out your hard drive for other reasons, just an FYI)
