    I currently have a GTX 680 Classified 4GB Card and wish to modify the original rom and add EFI to it and then flash it. I have been using the ROM provided by Dr. Stealth and Fl0rian and it works great with macOS but when i dualboot on windows the drivers go haywire. Therefore, i would like to modify my original rom so as to eliminate any potential complications given by the vBios. Could someone post a detailed guide on how to go about modifying it?

    EFI flashed or OEM cards are hybrid roms so there should be no issue
