Sorry for the confusion John.

pxelinux works and it loads the vmlinuz and initrd.

Actually I have dhcpd configured for static IP address.  Not for a  
range of IP addresses to pick from.  dhcpd is running.  After PXE  
loads up the kernel, I think the installer anaconda uses dhcp to again  
look for the ks.cfg file.  This is after the menu.  That's the part  
which does not work.  That's why I put in the static IP's in my  
default file under label 1.  Putting the static IP's don't work as well.

Thanks
