dell repo error

[Adam Williams]

have a fedora 8 x64 system i'm trying to run yum -y update on (yes i 
know fedora 8 is no longer supported by fedora) and I get the error:

http://linux.dell.com/repo/software/fc8/x86_64/repodata/filelists.xml.gz: 
[Errno -1] Metadata file does not match checksum
Trying other mirror.
Error: failure: repodata/filelists.xml.gz from dell-software: [Errno 
256] No more mirrors to try.

any ideas?
