socket7.....
BUT, this might be a chance for your friend to upgrade to something new...
but that might be more money than buying a new board, because he will need to get new ram, heatsink, etc.
but i would say to look into a socket7 motherboard...as this is what you need to run that processor.<A HREF="http://www.directron.com/va503.html" target="_new">http://www.directron.com/va503.html</A>
as you can see, they arent that cheap...but it will work.
and this one i linked you to, the VA-503+ by FIC is a good overclocking socket7 board...because it has a bunch of jumper settings...
but even if you arent into overclocking, then it will be a decent board for that processor.
i would see if your friend has the money to possibly do a system upgrade tho...because you would be better off in the long run.
