I was pointed towards this thread when I had trouble isolating my 1070 for PCI passthrough.   Long story short, I tried dumping my vBIOS like instructed in the video, but couldn't do so (the `cat` command printed I/O errors instead). Instead, I resorted to dumping the full vBIOS under Windows and using a hex editor to splice the relevant part of the ROM into a new file, using some of the partial vBIOS files uploaded here as samples. This finally allowed me to pass the GPU to the Window
