Well, this is very interesting. I read the thread and noticed that my CD situation on my A4000 is set up pretty much exactly as yours and I couldn't get the OS to recognize the CD drive as well, but I eventually did for awhile, just long enough to install OS 3.9. THEN I changed a couple of things, like a 2nd and larger HD. It works just fine but the CD doesn't anymore. I suspect there must be a jumper situation like you described that is throwing me. Lets hhope you have given me the clue I need. Well, you probably aren't hoping since you don't know me from Adam, but I sure as hell am hoping. I know the 2nd HD is the slave, but I bet it is interfering with the CD somehow....
