upgrading the kernal

[Darragh]

hello again
i've tried reading the howto at
http://www.redhat.com/docs/manuals/linux/RHL-7.3-Manual/custom-guide/s1-kernel-perform-upgrade.html
with no success.  note that link will bring you about three pages into the
howto but that's where I got the commands
rpm -uvh kernal name where kernel name was the file name.

I'm getting an error about a bad tag or something.
