Yeah, I couldn't get sound to work, but I didn't try USB. I couldn't figure out how to get ethernet to work. I remember getting it to work on my old 9600 but I don't remember how, so I might be doing something wrong. I can't get Blue Box to boot, and I can't change the brightness on the display. I also found out it doesn't go to sleep when I shut the lid (found that out the hard way). I also have no idea how to eject the CD from the drive.
My computer is also a blueberry, and it's one of the OS 9 ones. I think I'm just gonna play around with the newer OS X Developer Previews instead. OS X Server 1.x can go back to my 9600.
