the best way to do it is wit a mod chip. i would go with the smartxx. go to xbox-scene.com for more info. it is possible to emulate windows within linux but it would be easier just to learn linux. also with a mod chip you can swap your harddrive out for something a little more accomodation like a 120gig.
maybe u are just dumb to want an xbox on a com, the xbox graphics is great itself... and u want a com??? i dunno, there are plenti of mad pple in tis world
You could always install linux then run a windows emulator. Or install more ram in your Xbox and run linux of of a stick of it, then it would be like lightning heh.
