I am having a problem when trying to add EFI to my original BIOS on my XFX Radeon HD 5870. After running the following command in terminal I get a permission denied and it doesnt work. I found another thread with very similar commands only its myrom.rom rather than XFX5870.rom

blocknum=`printf %d "'\`dd if=XFX5870.rom bs=1 skip=2 count=1 2>/dev/null\`"`
size=$(($blocknum * 512))
dd if=5870_uakari_netkas.efi of=XFX5870.rom bs=$size seek=1 conv=notrunc

I renamed my original file to match each command. The myrom.rom method worked however when opening the file with TextEdit I only have 1 mcuc. I've download 0xED to try and edit it per the post but the program will not allow me select anything. I've attached my Original BIOS can someone please assist me and adding EFI to this?

Thank You

Go over to the port mapping thread. It helped me stitch a rom that gave me boot screens. Follow the guide but make a back up of your original rom first.

Good luck

Thanks, I'll check it out. I was just considering buying a new native card altogether so I don't have to deal with it. Is the Sapphire 7950 the newest card that came out with native OSX support?
