Have Fedora 12-x86_64 on a separate disk to Fedora 11-x86
Want to boot F12 from F11 grub and if testing in the F12 environment I 
want to boot into F11

Altered /grub/menu.lst in Fedora 11 to include the kernel and initrd 
from F12, it won't boot.
Altered /grub/menu.lst in Fedora 12 to include kernel and initrd from 
F11 , same result.

Tried

map (hd1) (hd0)
makeactive
root (hd1,0)
chainloader  +1

won't boot.
