Bootcamping Windows XP

Following the insertion of a new and larger HD on my Mac Mini, I would like to Bootcamp Windows XP onto the new HD since it is the only OS that will run a specific software program that I have. My question then: if I do indeed prefer to do it through Bootcamp, can I simply substitute my original Windows XP disc in place of Windows 7 disc (the only option offered on my current version of Bootcamp) when Bootcamp calls for the Windows installation disc, or do I need to find an older version of Bootcamp that would work specifically for Windows XP? If so, which version and is that available as a download from Apple?

I'd be grateful for any help and advice. Thank you.
