Mac OS 9.2.2 install on G4 MDD

Hi,
I'm salvaging a G4 MDD and looking forward to run OS 9.2.2 on it. I have the original system disc, but I heard that it's gotta be speciffic for that model to boot up. How can I get it to boot on 9.2.2 and have sound support as well?

You are correct. You require the Mac OS ROM version 9.6.1 from the MDD. You can either get this from restoring manually or the OS9General.dmg off the CDs.

I uploaded these CDs here http://macintoshgarden.org/apps/macintosh-system-922-1021-power-macintos... for anyone else

whats the problem with the sound? If you have the original install CD, should be no problem at all. Anyway, these links to the MacOs9 updates will help you:

The major upgrade is the 9.2.1
Once installed, go for 9.2.2.

Is there a fan control program to run under Mac OS 9.2.2? My firmware is up to date, being 4.4.8f1.. but yet when I boot into OS 9.2.2, the fans roar.. while in OS X it is quiet as a mouse.
