I had to do a rebuild on one of our Rental units. Went to the site for pcchips (slow).
MB is a 754MLR. After a search on www.google.com I found a different site which was http://www.pcware.com they have all the drivers that pcchips make a the site does work. I do not recommend this board and pefer dfi amd asus mbs. but if you need a driver this is the place to look.
