When you put a CD in can you eject it ? , basically if you keep pusing the CD eject button does the tray go in and out? If so the machine has no idea the driveis connected and you'll need a 3rd party extension to make it work.IIRC there was ONE version of Apples CD ROM extension that supported almost any drive but I can't remember which.
However if you go to lowend make and look at their Daystar Support pages one of the downloads is for CD ROM toolkit which will work with almost any CD ROM drive, it also has a little control panel to let you do some funky stuff with the drive.
Incidentally, I haven't seen it mentioned here, there is a neat little extension called CD icon killer. What this does is force all files to use their generic icons and speeds up CD browsing quite a bit on 68K Macs, especiallay when using magazine cover discs.
