second Linux distro on second hd

[Doug]

Is there any trick in putting a second distro (Ubuntu) on a second drive 
and booting either one with grub?
This is an older computer with IDE drive capability only, and I don't 
want to invest a whole batch of money into it, by upgrading the mobo, 
etc., but I can probably scrounge up an old IDE drive someplace.  (I 
would not replace the PcLOs distro that I'm running on it now.)
