Sorry for the post, I fixed my own issue. After looking into this more, miniroot.gz did not change to minirt.gz. I was trying to grab the files off of the CD .iso but I forgot that it is a real pain in the butt to get a hold of both "linux" and minirt.gz since you can't get them this way. Instead you have to boot up a copy of the knoppix distro, start knoppix terminal server so that the /tftpboot dir is created, and then copy off these files from this dir. What a pain.
