Hi

I have an HP Pavilion g6-2151sp i have my BIOS on version F.14 , I want to unlock anything possible on it, e specifically:
This laptop has 2 graphics cards..and I only want to enable one of them.. I have successfully Installed Mac on it..but the graphics card that is recognized is the second one..I'd like to have some kind of "Switch" to enable just one.. Pleasee!! **
