Ok, First question. When I boot up my mac, If I go to activityu moniter there are two things that come up in red writing. 1 says Core Audio not resp. and the other says something about User Event. This also happens on my Powerbook G4. Thought it was my copy of Leopard, but tried another and it says the same thing. I can force quit them and they are fine until i reboot. Also, I dont seem to have an audio problem. I mean it still works. Any ideas? Second question. My G5 runs Debian on one HDD and Leopard on another with Yaboot. Can I partition one of the discs and install OS 9? Would that be a problem with Leopard and if all would be ok, would it show up on yaboot as a boot up option along side of OS X and Debian? Thanks for your time and help!
