Hello, I'm new here but I hope you can help me all the same, I have a Mac Mini G4 and have taken out the Combo Drive and put in a Superdrive in it's place. Tiger doesn't seem to be recognizing it in the system profiler and I don't dare put a disc in to try it out because it will probably just stay in there. The new drive is a Panasonic UJ-845C, says manufactured to Apple specifications on the front. I have tried looking at the Open Firmware but that doesn't seem to do what I want. Now do I need press some other key combination on start-up, is it something software based or do I have to install some new drivers of some sort. It is of course possible that it is a faulty drive, but I'm hoping that it is just down to something I haven't done. Thanks in advance.
