Patching vBIOS on NVIDIA 435.21 no longer works #4

Hey Guys,

I've just tried using the 435.21 driver with the NVIDIA vBIOS patch however it doesn't seem to load correctly.

...

I'm running a Quadro P520 (GP108) / Basically an MX150. It's possible NVIDIA have changed how the vBIOS is loaded?

I was using the wrong vbios.
