First of all, you probably should be installing Fedora Core 6, not 5, since it will soon be removed from active status. Fedora7 is now in testing. If you'd like to install Fedora Core 6, here's the main page for that:
http://fedoraproject.org/wiki/ and if you have bittorrent, you can download the latest version of Fedora Core 6 from here:
http://torrent.fedoraunity.org/
Now, if you don't have internet access and have the FC5 CD's or DVD already and really want to install that version, here's some installation notes on that:
