• Instructions
◊ Startup Player is a definitely cool extension that plays a sound over and over until all other extensions have loaded and the Finder comes out. The sound must be in a Finder sound file called "Startup Loop" inside the Extensions folder (or in the System folder if you’re running System 6). Since you’ll want Startup Player to start playing early in the startup process, you may add a space before the extension name. If you’re using some kind of startup manager, put Startup Player among the first extensions to load (see notes below).
◊ QuickTime 1.6.1 and 1.6.2 seemed to prevent Startup Player from playing its sound at startup, whereas version 2.0 works fine. You should install QuickTime 2.0 if you haven't already done so.
• Notes on the Sound Manager 3.0 extension
◊ Startup Player works well with the new Sound Manager 3.0, but both the Sound Manager extension and the QuickTime 2.0 extension must load before Startup Player. If you add a space before Startup Player’s name, you’ll have to add spaces before both extensions’ names as well. If you’re using a startup manager, make sure QuickTime is loaded first; the Sound Manager must follow, and Startup Player should be the last.
• Memory warning
◊ Startup Player releases all of its memory when the sound stops playing, but the sound has to stay in memory until the startup process is over. Using a very large startup sound makes your system heap grow larger (even if the memory is released and free) because other extensions usually allocate memory that can’t be moved around. Try experimenting with various sound sizes and checking the Finder’s memory window to make sure you’re not wasting memory.
◊ System 6 only: the system heap is not as smart in System 6 as it is in System 7. Startup Player may not be able to load large sounds under System 6 unless you add a specific 'sysz' resource to it (I can’t do it because I don’t know how big your startup sound will be). The 'sysz' resource should contain a 4-byte integer equal to or larger than the total size of the 'INIT' resource plus the 'snd ' resource you want to play. Don’t try to add a 'sysz' resource if you’re not a programmer, just use a smaller sound and everything will be fine. Also, don’t distribute Startup Player with a 'sysz' resource in it because the 'sysz' is size-specific and other users may end up wasting memory.
