There is an additional complexity from fc6 -> f7: the way disks are 
accessed in the newer is via /dev/sdX whereas the old would be /dev/hdX 
for parallel IDE disks. I imagine that the kernel in the installer also 
provides a good check as to whether the machine can actually boot such a 
kernel. There is good information available eg:
