Thanks for the responses last week but I've been unable to follow up till
now.

The device.map is from the FC3 installation which lists hd0,0 whereas the find 
/grub/grub.conf finds it on (hd2,0).  When I ran the above commands (root &
setup) things worked fine but I still end up with the system halting at GRUB
when I try booting from the HD. I had changed the grub.conf file to refer to
the (hd2,0) instead of (hd0,0)

So it isn't finding the /grub/grub.conf?  Now what should I try?

Thanks
