System extension which will keep certain Macintosh models from making the usual chime at startup or restart. Useful particularly for PowerBook users who find themselves in an environment where the chime would be disturbing to others. Quiet Start takes advantage of a change in Apple's ROM on some later models (like my PowerBook 160). With this change, the volume level of the startup chime depends on what the user has set it to with the normal control panel. Quiet Start sets the volume level to zero just before the Macintosh shuts down. When the system extension is loaded at startup, the volume level is restored to what it was before you shut down. Please be aware that because your Macintosh may not have a ROM which checks the volume level before making the chime, this program may have no effect on your computer. Sorry, there's nothing a program can do until it's running - and bootstrap ROM always goes first.
