I don't know if yu've heard of Boot Camp - but it's a legal program made by Apple to allow Windows OS to run on a Mac. I don't know how it works or anything, sorry. But methinks that he will do, yeah.

EDIT: I was right, he will.

There's some info about Boot Camp. It's at Public Beta stage atm, so it's free to download.
What you need for it to work is:
Mac OS X Tiger v10.4.6
The latest Firmware update
10GB free hard disk space
An
Intel-based Mac
A blank recordable CD
A printer for the instructions (You’ll want to print them before installing Windows, really.)
A bona fide installation disc for Microsoft Windows XP, Service Pack 2, Home or Professional (No multi-disc, upgrade or Media Center versions.)
So, if Asamin's computer is a few years old, he probably won't be able to use Boot Camp:
It's a new program that makes advantage of Macs now being made with Intel processors. So if he doesn't have an Intel processor in his tower, he ain't gonna be able to use it, sorry. It also needs Mac OS X Tiger v10.4.6 which, for all I know, could be the latest Mac OS, or one of the first few. I really don't know much about Macs.
