Parallels 6 and Windows XP.

I have a copy of Windows XP SP2 which I am trying to install on my MacBook (i7 2 GHz) running 10.6.7.

Bootcamp will only install Windows 7 which I don't want to buy. If I upgrade to Parallels 6 (I have v2.5) will it the allow me to install and run Windows XP?

Thank you
