Thanks to all for the information on the duel boot setup. I think setting the swap on one disk and Linux on another is a cool idea. Incidentally I got a second 7200 RPM drive instead of the 5400 I was going to get. When I went to install it I find out that the slide brackets included with this Dell Dimension L system do not seem to line up with the screw holes in the drive. I always was under the impression that all 3.5 inch drive bays were the same. It is not the drive bay that seems to be the problem but the bracket/clip things that fit onto the drive and slide into the bay. If I could get the right clips I would have no trouble installing the thing. Can other clips be purchased? I am trying to mount the drive into the 3.5 inch bay under by 5.25 bay. The bay is meant for an external drive but I never new until today that this would make a difference. I guess it may be time to go and post a message to Dell. Doug
