Compaq motherboard drivers for windows xp ms-6577 ver:4 1

Try THIS LINK. That board was in the Hp pavilloin a705w so I went to their page and found the mentioned drivers. Try them if they're the wrong ones they either won't install or they will and won't help. If they're the right ones - TA DA.
However, if it came in a different machine look on the website under the machine name and not the motherboard name. You will get some results that way.
