@CaseySJ I found interesting thing thout after successful install. If I used iMac20,2 in config.json - then I experienced system instability - usually Finder stopped working properly, computer started to hang and so on. No certain pattern, but eventually I had to reboot every time.
LOL - I like that name - Society of Mad Scientists :D
I didn't dig deep into the customizing Thunderbolt DROM - I used one you prepared and uploaded in your tutorial. Read it, checked it (manually) and used after that. Just need machine to be in work condition today.
@CaseySJ Thanks a lot for such a very thorough guide. I was able to install Catalina with i7-10700K on Vision D in almost one click with modified Thunderbolt ROM. Works like a charm, didn't figure out any issues.
Hardware I used:
Intel Core i7-10700K Desktop Processor
GIGABYTE Z490 Vision D...
