Absolutely ridiculous as you idolized macvidcard and rominator here. I don’t beleve that the two guys have really written the EFI part from scratch - i think they have just analyzed the EFI part of various existing Mac ROM’s, certainly very elaborate, in order to make the necessary adjustments for newer cards. I do not want to belittle their work, but to idolize people is ridiculous. They make a lot of money by making such a secret about the whole thing. I would like to know if it’s really rocket science to built such a ROM File.
