Well, I'm replying to this in XP.  I got it to work with hd1 for XP and 
hd0 for linux.  I also had to put the map (hd0) (hd1) and map (hd1) 
(hd0) for XP to boot.

The wierd thing is that if I'm in Linux, and do a 'df' it shows root 
mounted on /dev/hdb1.  So the way I understand it, that means that I 
couldn't boot to linux if I have root (hd0, 0)....but that is the only 
way it works.


Basically I have no idea why it is working, but it is working now...
