Unfortunately, the problem is that the documentation is out of date
for Fedora 11, because the checksum used was switched to SHA-256
instead of SHA-1.  A bug has been opened to update the documentation.
There is a little bit more information in the bug report:


There are some windows sha256sum binaries listed in the bug report,
but I am not sure any of them are suitable for the Fedora Project to
recommend to users.  But I have no doubt that between the Fedora
documentation team and the other great folks in the Fedora community,
this situation can and will be improved.

FWIW, I can attest that the SHA-1 of the Fedora-11-i686-Live.iso is
795b52b3c7b16eba6f2cae055ec894d8648d8095.  (Now, whether you have any
reason to trust me is another matter. :)
