Hello,
whenever I try to install Fedora Core 3 disks 1 and 4 verify sucessfully, but 2 and 3 do not. I have redownloaded both of them and then reburned, and they claim to be burned properly.
Have you tried booting with "linux nocddma" or "linux ide=nodma"?
This is the usual workaround for this problem.
Paul.
