Going to be reformatting a couple of comuters for friends in the upcomming days. Both are Dell's. One is a dekstop and one is laptop. The desktop still has a recovery disk, while the laptop does not. When I install XP on them, will the built in XP drivers be good enough or am I going to have to go download a butt ton of drivers for each machine from Dell? Also, anything else I need to know ahead of time about wiping a Dell machine? Thanks.
