Mactracker won't tell you if a previous owner took out the superdrive and replaced it with a simple CD drive. That seems unlikely, but it's possible. Once you get into OS X, go to the Apple menu and pick "About this Mac". Then click on "More Info" (I'm sitting at a Windows PC right now, so I might have the wording slightly wrong). Look for "Disc Burning" to find out what drive is really in your iMac. As for ejecting the CD, you can do that in Open Firmware. Right after you turn it on, hold down Command+Option+O+F to get into the Open Firmware. It will tell you when to release the keys. Type "eject cd:" to eject the CD, then type "eject cd:" again to close the tray (unless it's a slot-load drive). Finally, type "shut-down" to turn off your iMac. -- Rich > -----Original Message----- > From: g4-bounces at listserver.themacintoshguy.com [mailto:g4- > bounces at listserver.themacintoshguy.com] On Behalf Of Rick Barrett > > Hi G4 Gurus, > > I sure need some help. > > Just got a 15" flat panel G4 iMac (Codename Tessera, P80) that had OS > 10.2 on it, but lacked system or dock prefs! > > Mactracker says this 800 MHz model shipped with a CD-RW/DVD-R > "SuperDrive", but when I put my OS X10.4 install DVD in it it didn't > spin up, but ejected it after a few seconds, so I then decided to > install 10.3 and worry about the drive later. > <snip> > > Not only that, I can't restart on any disk except the 10.3 install > CD (which just eventually gets me back to the panic) and can't open > the disk drive (no paperclip hole like every other Mac i've ever > had), mouse button down on restart doesn't work, F12 doesn't work! > What now???
