Removing OSX startup sound

The startup chime is independent of OS X I believe - it's set in the Open Firmware.
Mute the volume on your Mac before rebooting or shutting down will disable it.
Might be a way to turn it off permanently in NVRAM settings but probably not a good idea.

OSX can control the boot sound. There is debate as to weather it is in the firmware or not.
Start Up Sound Preference Pane- This will add volume adjustment for the Startup Sound to the System Prefrences. You can mute it if you want.
People have attempted to change the Korg startup chime for years. (At least from OS9) It is really buried deep and is likely not just a discrete file, but rather part of a larger meta structure. It may not be compressed, as it comes up so quickly, and it just wouldn't make sense to have an audio decompression program just to unspool one sound. As far as I know it's still ROM based. You could get an old mac and look at the ROMS. If you understand how soundfiles are structured, you have a good chance of finding the elusive sound. If you think it is on the HD, I'd just grab a hex-editor and start scanning the disk, looking for tell tails.

I think its built into the logic board and not any specific version fo the OS. SOME functionality comes from the logic board when no hard drive is connected, and this is part of it.

It's a Korg, here is the history of the chime. I think there is a video floating aroud with Jobs and Jim Reekes talking about the orign of the the chime.
Thanx for the answers guys.
Find it a bit weak that you can't remove/mute the chimes. With out muting before shutdown or by installing additional software that is.
I'll just go with the mute at shutdown option then.

Use this:
http://macupdate.com/info.php/id/16425, its called Startup Sound Preference Pane.
There is no way to change the sound, but this preference pane allows you to reduce the volume or turn it off altogether.

Three people recommeding this (and 2 posting links), should show you the prefrence for this over PSTT!!! (also noted above). The problem with PSTT, is that it only mutes the chime. To get the sound back, you have to run an uninstaller.

Cool. Hey, I love the chime... just trying to be helpful for the person while checking versiontracker (also in my post qualified it by saying that I haven't used it...) - just giving them another option....
but it was stated that it works without HDD.
so... built into hardware, controlled by OS. ?
My bet is that it's firmware-controlled, but the volume parameter is stored in NVRAM, thus allowing the OS to control it by changing the stored value.
But, when I zapped the PRAM on my Mac the other day, it bonged again. Maybe it only works during a normal boot or something?
Nope. The PRAM is where the startup sound volume setting is stored.
