Hello,
I finally have installed High Sierra with your Image on my P5Q3 deluxe mobo, have all done like described.
The Problem is my GeForce 8400 GS nVidia Graphic card does not work. I only can boot with nv_disable=1 and get 1280x1024 resolution (not enough for me). It was working properly in Yosemite 10.10.5 after unishit Install.
When I inject nVidia in Clover I alwas get crashes on Boot. Any Suggestions? How get higher Resolution?
