In my experience (grub legacy, linux boot with /dev/hd* device names, years 
ago), I had to play with device map to be able to reorder boot device priority 
(or plug HDDs in a different PATA layout, I don't remember precisely).
I could edit the map to fit the intended layout change, grub (without
--recheck) just followed, and machine could boot just fine.

Nowadays I don't have to care about this, thanks to UUIDs everywhere instead 
of dev paths.
