Many thanks for these step-by-step instructions! They've been enormously helpful for a non-hacker noob like me.

[mactenaka]

This is great. haven't tested, can we get a confirmation by someone else and get a sticky? props to JGene

[weeeee]

will try this method out now. i'll let you guys know how it turns out.

EDIT:
I was unable to proceed with some of the steps.

-There was no option for the RC3 bootloader in the NetBookMaker app. I am using the 0.8.2 release.

-I could not open the Extensions folder in preferences. It stated that I did not have the right permissions. I tried viewing properties and it shows 0kb.

I confirm that this work very well. I am using this solution to get sound on my mini. It even survive resume from sleep ;-) when they work due to the fact that I have a 8GB STEC SSD ;-(

Weeee: Try downloading it again here: netbook-installer - Project Hosting on Google Code

I'm in the middle of giving this a shot. So far everything is going according to the tutorial.

[edit] Sound and sleep works great! Thanks for the info / well done tutorial.

I'm currently on Section C - Installing the Voodoo Kexts for Audio
However after I doubled click on VoodooHDA.prefPan, click oK on the confirmation screen. Then I got this error message

Error
Can't get registry-entry path

Any idea?

Steps worked 100% perfect for me.

I got that too, it was irrelevant. Everything still worked in the end.
