Success on OpenCore AMD FX-4350 + 8800 GS

[w32u]

After the second attempt my 8800 GS successfully started on 10.15.7 with OpenCore

I followed these steps to install the patch:

1. Install macOS Catalina
2. Install all updates
3. Patch NVIDIA GPU like it's said on https://dortania.github.io/OpenCore-Post-Install/gpu-patching/nvidia-patching/
4. Reboot and check if it's patched (model and VRAM size are correct in About this Mac window)
5. Disable SIP and set SecureBootModel to Disabled as described here
6. Reboot and check if SIP is disabled. In terminal type csrutil status, you should get something like that:
   
7. Mount system partition as r/w with this command: sudo mount -uw /
8. Install Legacy Video Patch as described in the two videos
9. Reboot and enjoy

Some photos

Two monitors work (there are two DVI-I port and S-Video port on the graphics card, the fist monitor is connected with VGA via DVI-I - VGA adapter, the second one - with DVI-D cable)

Hope this guide will help anyone using OpenCore and getting kernel panics. Cheers!

Thanks for the details but sudo mount -uw / is not necessary because is already use by the program
