I just found out a way to completely automize the rom creation process. what does this mean? well, paired up with pipomolo42′s pythonscript, the end of searching for roms on macrumors for 4870/4890 cards! with the push of a button, EFI support will be added to any 4870/4890 rom file. It’s still not finished, but it will be included in next zeus update. Theoretically this function could be expanded to support future cards such as 5870, but first Apple must release the card so we can dump it’s efi part.
