Since HP doesn't support XP on that model you'd need to go to the component manufacturer's website and see if they have a compatible driver. Everest can give you the information you need in that regard, but before proceeding be sure you actually need said driver(s). (ie what problem are you having?)

I installed XP over vista and now I seem to need the motherboard drivers for my pavilion a6200n. Any idea where I can get one (or them?)
