All these methods are similar, actually the process of making efi strings is the same always. You can go and compare. Did you add your device id properly? Flush extensions also, and rebuild them.

Take care.

** One of the friends recently told me that he can't get QE/CI with 8400GS on Vaio. He gets quartz but only on external monitor while internal laptop screen remains unsupported. You can go also do some research on this.
