How do I Dual boot vista and XP with two hard drives?

I bought a new computer with Vista installed on it. I have an old computer
with xp on it. I plan to add the old hard drive with xp to my new computer
so I would have both hard drives and both O.S. on one computer. I would like
to have a dual boot option between the two systems/hard drives. If this is
possible can someone give me some detailed instructions on how to achieve it.
Thanks in advance for your help.

If XP came preinstalled on your old computer (OEM) then the license does not
permit moving the OS to a new computer, even when you move the whole hard
drive and all. If it is a retail copy of XP I suggest that you run XP in a
virtual machine on your new computer and avoid the whole issue of dual
booting. That way you can run both Vista and XP at the same time instead of
having to pick one or the other.
