switching between amd64 + i386

[Hugo Vanwoerkom <hvw59601@care2.com>]

Hi,

Since I have a new amd64 mobo, M4N98TD EVO, I am about to do an amd64 
install.

Up to now I have run from partitions that were 1386.

And a question: how does switch between an amd64 and an i386 partition work?

Now I am running i386 and grub i386. But when I want to boot the amd64 
partition, whose grub is used? Or does the MBR automagically pull the 
right grub in?
