BCDedit? help me find my xp install from withing Vista

I have a new Vista install on a RAID 5 drive C: while I also have a
previously installed version of XP on another hdd alongside a "dead,
deactivated" vista.

I would like to add my XP boot record to my RAID 5 bootup. Do I need to
transfer boot.ini and .. . from the XP partition?

I believe this problem is more complicated, bc I already have a bootmgr file
created on the single hdd, since I previously installed Vista on it...

So what am i looking for to merge my 2 boot records and always boot up
within my RAID 5 drive??

Thanks for your help
