I bought a 2GB 680m with a Dell vbios and would like to use it in my Clevo d900f. The card boots fine but only shows as a vga in bios and I cannot load any drivers in windows other than the MS basic display adapter. I'm a bit weary of flashing a 4gb vbios. Nvflash stopped my attempts with a Board ID mismatch error. Can I force flash a clevo or nvidia 4gb rom? Can I edit the existing rom and change anything and make it fully work in a clevo? Is there a 2gb 680m clevo rom already? 2gDell_680m_original.rom
