Is there any way you could borrow or transplant an AMD GPU for a short period of time?After experimenting with the @BoBo88 EFI (with small changes, see spoiler), I at first thought I'd made some progress: at least I was getting to the Apple Progress Bar before going black. But then I added "-v" for troubleshooting and I got the same result as before. In fact, I was able to go back to my own EFI, minus the "-v", and got the same Apple Progress Bar as with @BoBo88's EFI.
So now we know that the problem is not in my EFI -- or at least he and I are making the same mistake.
What next? Do I experiment with a Framebuffer patch? Other ideas?
