I've installed Core 3 final on my IBM 600E, and the sound doesn't work. I'm not sure where to start, as I don't know much about this sort of thing, but if anyone has a question to get me started, I'd appreciate it. Furthermore, whenever I try to use the CD Player, all I get is a message on the application's window that says Drive Error. If you need more information, tell me how and what I need to get, and I'll get it. Thanks!
