Boot Chime

[busterfelix]

This is my method that will play the boot chime after the splash screen but before the login window. Occasionally, and possibly always on your system, it will play before the apple splash has completed. I know it’s still not in the right place (but at least earlier than any other method I could find). However, if you are logging in automatically you are better off creating an applescript , saving it as an application and adding it to your login items in users pref pane if that’s all you want. That is easy and can be googled.

 

What my method does:

 

These instructions load all needed audio kexts during the apple splash screen. Then at the end of that and before the login window, the plist file (see below) will invoke the boot chime aiff file resulting in a playing of the sound. I would like it to play earlier but cannot find any way within the scope of my skill to make that happen. Besides, messing around with the actual bios with non manufacturers flash updates sounds a little scary

 

What you’ll need:

1. First your audio must be working. Mine uses VoodooHDA and I have not tested this with any other audio kext.

2. The attached plist file and place it in “/System/Library/LaunchDaemons”

3. Find and download “pfix”. You may already have it if your installation came with a folder in the root called “Hackintosh Tools”. If not, just Google of course.

 

Now after you have completed step 1 and 2 of the above, we need to get your audio kext(s) loaded into the “/Extra/Extensions” folder.

 

Simply go into the “/System/Library/Extensions” folder and copy your primary audio kext i.e. VoodooHDA.kext and paste it into the “/Extra/Extensions” folder.

 

Now you need to download and install the G3.aiff file and place it in “/Extra/MacChimes/” you must create the last folder.

 

You can try to run pfix now and reboot. It may work. I say “may” because if it does not, like it did not with me initially, I did the following additional copy and paste.

 

Go back to “/System/Library/Extensions” and search for any kext with the word “audio” in it several but not too many should appear. Select them all and copy and paste into “/Extra/Extensions” and run pfix again.. Now of course reboot and it should work.

 

*READ FIRST

 

You will benefit from having an almost duplicate (i.e. custom for your system) osx86 installation on a flash stick or separate partition. That way you can easily use that to access the modified folders and undo all of the above in the event you get a kp. You shouldn’t get a kp, but I always like to be careful when I goof with my system settings. Otherwise you will have to try safe mode and/or single user mode to undo changes.

 

If after doing this you would like to experiment with the plist file, download and install "lingon" the demo will work just fine.

 

4/20/11 As this process took me about two days to work out, I don't know if I have it in me to continue tweaking right at the moment. However, I have noticed that the sound event plays earlier sometimes while the splash screen is up and still spinning. If anyone can find out why or how and how to get it to play even earlier, that would be awesome. reply to this post for questions about any details of loading sequences if you want (hopefully to help).

If anyone know step by step how to do the BIOS modify method to get boot chime at boot, that would be great. I have a Gateway MT6821. thx
