I think this is the problem. Isn't flashing the BIOS risky in old computers? I'm not even sure what motherboard is in it, it's an Award BIOS, I'll have to install Everest or something and see what the motherboard is, it's not going to be one that's common though, not one that you can buy seperatly in shops, as I said it's one of those horrible shop setup ones...you know, like a "family computer", some mini-atx thing. It's mostly used as a backup and for testing things out. You're right I can't select a dvd drive in the BIOS....but I don't think I can on this (newer) computer, I think it just calls it a CD-ROM drive in the BIOS but is a dvd and will read dvd. I'm not even sure The drive works fine, XP detects it automatically and will work with dvd or cd no problems, on 9x it wont read dvds until I install the driver but will read cds fine. I've read the disc's content in windows on that machine with that dvd drive so I think it's the bios problem in the post above
