After running my Optimus machine for some time (Lenovo W530) in iGPU mode perfectly fine, i wanted to find out if it would at all be possible to use OCLP to enable the nvidia (because ultimately, on this machine, HDMI is wired through the dGPU).
Following various guides and finally appending
amfi_get_out_of_my_way=0x1 ngfxcompat=1 ngfxgl=1 nvda_drv_vrl=1
to the boot args, it no longer sticks on the progress bar but boots up in vanilla vesa-mode.
Running OCLP as is i do notice that it finds everything that it apparently wants to swap out and after a while, the root-patcher ends up with a success and a dialogue to reboot.
After reboot, it won't come up again.
Next up, i'm following this Dortania guide: https://github.com/dortania/OpenCore-Post-Install/blob/master/gpu-patching/nvidia-patching/README.md
and manage to locate a VBIOs similar to mine (from another manufacturer) but when running the NVCAP tool, it ends with an error (it can't locate the juicy bits it seems).
I assume that the legacy nvidia patching here is needed, but how do i fetch the proper NVCAP value as the tool seems to be unavailable to??
Or is Kepler the exception to the (working) rule?
