Got a new lap top running XP home edition, my game wont load coz XP doesnt have DOS,even though xp reckons it CAN run any old game I cannt figure out how to configure it for the Xwing game. Any one got any clues? :D

Use DOSBox, works fine for the most DOS-Games.
At least you may give it a try.

Getting an old computer and run it in pure DOS however is the best method ;)
