The number "N15235" is not the actual model number of the motherboard. It is a regulatory compliance code (similar to a serial number) found printed on the board near the PCI slots or the motherboard battery. Foxconn printed this code on many different motherboards, so we need the specific model number (e.g., G31MXP, G41MXP, 45CMX) to find the exact manual. Vegamovie.com Nl Direct
