I neglected to mention when I did a genfstab I used genfstab -p -L /mnt 
> /mnt/etc/fstab in all installation attempts.  One thing not explained 
on the beginners guide is what does labels buy you as opposed to what 
does uid's buy you with genfstab.  Also, I did learn syslinux does not 
support xfs the root of the disk could not be found whenever I used xfs. 
 Grub-legacy I think is gone and grub-bios didn't work and neither did 
lilo.  I can try more things later but not without some suggestions and 
sighted assistance to tell me what the next failing boot screen
