5.  Wait until the sha1sum checksum display on the screen, as show on example below .......................... then.........

E:\fedora_10\jigdo-win-0.7.2>sha1sum.exe Fedora-10-i386-DVD.iso

6.  Compare the sha1sum checksum that you get on the screen from the SHA1SUM that you get from the download server.  If the two key matching, the iso image is good... if not ... try download the iso image again.
