Hi: OK, I'm not a redhatter so this is all just speculation on my part. Firstly, I highly doubt that the setup program is able to cope with an ISO image, nice though that would be. You can get around this by mounting the image like so: mount -t iso9660 -o loop /path/to/imagefile /mnt This way, the file will now just look like a set of directories on your system. However, I am very surprised that there isn't an upgrade procedure that doesn't involve reinstallation. You might want to check (if you haven't already) that this is indeed the way you should be upgrading. Geoff. -- Geoff Shang <gshang10 at scu.edu.au> ICQ number 43634701
