I have Ubuntu on my Master hard drive and XP as its slave (heh). My hard 
drives in this machine are just plain old (parallel) ATA though so ymmv.

When you install Ubuntu it will automagically set up GRUB to dual boot. 
If you then install other OSs or reinstall Windows then you might have 
to faff with the GRUB settings (see below). XP won't (in my experience) 
install if it's not master but will boot happily from any drive via GRUB.

Changing the GRUB settings is really easy if you need to (and there are 
plenty of guides on the internet). If you're not sure/want to be 
safe/don't know the exact command at the time you need it most then I'd 
recommend burning SuperGrub http://supergrub.forjamari.linex.org/ for a 
semi-interactive "where has my OS gone" fallback. As usual, test it 
before you need it :)
