GeForce 210 Opencore - is it possible ?

[sektorcoder]

First of all thank you for your work, it allowed me to easily test a Mac with legacy Nvidia without much hassle and am pretty happy with it.
I started with a KVM - Clover in GPU passthrough mode (Nvidia GeForce 210) using a linux host and applied your work, everything worked like a charm.
Then I wanted to transfer the same functionality in an opencore AMD 3900x - Aorus Elite X570 bare metal system.
While everything worked fine (installation, settings, system booted, even patching the Nvidia card according to Opencore documentation) it failed after applying the legacy-video-patch.

The most usual error was this:

Do you have any tip on what could be wrong ? Are there kext dependency / functionality hell here or you suspect something more simple ?
I am totally new to this and I spent two days searching for similar errors and multiple opencore config tests without success.
If you suspect this is something complex a general direction to start learning on the matter would also help me.

Kind regards

I don't know because I use Clover for Legacy video patch so I can not really help you
see my EFI here https://github.com/chris1111/Legacy-Video-patch/files/5720249/EFI.Legacy.Video.Patch.Clover.r5127.zip

Ok, thanks for the feedback, I will check your settings.

I have the same kernel panic on OpenCore FX-4350 + XFX 8800 GS build, but my SMBIOS is iMac14,2. I've tried to boot up with -no_compat_check and amfi_get_out_of_my_way=1, but it eventually failed. Don't know how to fix it right now.
Steps to reproduce:

1. Install 10.15.7 Catalina with OpenCore and AMD 15h CPU patches according to Dortania guide
2. Install last update
3. Patch legacy NVIDIA card in config according to Dortania guide
4. Install Legacy video patch
5. Get kernel panic after installation

The thing is that Clover isn't supported anymore for AMD CPUs by AMDOSX community
I've also made post on Reddit about this problem with the picture of panic: https://www.reddit.com/r/hackintosh/comments/mi3jbc/kernel_panic_after_applying_legacy_video_patch_to/
