Syslinux - Mar 2007 - pxelinux.0...error: not a valid image; unable to load file

I am trying to update a computer from Fedora Core 4 to
Fedora Core 6. My plan is to do this using PXE and a
kickstart file. I am implementing the use of an FTP
and DHCP server. The computers I am updating are
diskless workstations, meaning they have no hard
drives and they boot off of the network. I have
configured my dhcp.conf file, my ks.cfg (kickstart
file), my tftp server and so on, but everytime I boot
the machine it states the following error.

Loading 172.50.10.122:/ks/pxelinux.0......error: not a
valid image
unable to load file;

I have tried just about everything to fix this problem
and I still cannot figure this out. I have been
reading over FAWS and guides for a week now and even
tried starting all over, but still no luck at all. I
am going to attach my config files below for your
viewing. I am asking that if ANYONE can help me with
this situation here, please do so. I have had two
previous postings with several people whom have viewed
it and no one has responded. I am at an ending point
and have no more ideas. PLEASE give any advice
possible so I can attemp to get this fixed and
working. Thanks

You're not saying anything about your hardware, yet this message 
typically comes from the ROM; and the format you're describing isn't a a
typical output format from any ROM I know.

Is 172.50.10.122 the actual IP address for your TFTP server?
