EFI EBC Evergreen rom hacked

Apple made two checks in their efi ebc driver for 5870 and 5770, to preventus flashing pc cards.

But nothing can stand against me:D

Sshot of first flashed(with ebc rom) 5870 running in MacPro


bad news,still no efi boot screen, good news, it should support macpro 1,1/2,1 now, more at forum thread


  1. thank you

    so we “should” be able to flash pc 5870’s and 5770’s for use in mac pro’s now correct?

    Hi !

    Sounds great. However, please, could you elaborate a little more so other people like me can understand the scope of what you did and why it is such an achievement.

    In particular, what new features/new possibilities does the flashing of these two graphic cards give to the user. Why were the protection put in place by apple necessary in the first place ? (what’s in it for them)
    And, what kind of protections (two) are we talking about.

    I am jus being very curious. Thanks for reading me.

    Congrats netkas, this is much like the work i did on my 9800GX2 to get it working in my Mac Pro, I had the card initialising itself, no EFI boot screen, but full support in the OS.

    Does it make sense to flash a HD5770 PC version for hackintosh or does this only work with real MacPros?

    Evergreen is codename for RV870 chipsets (Radeon HD5800s).

    I was thinking, would we have efi boot screen if the first card was an original 5870 and the second a flashed one?
    (providing enough power was supplied to the cards, obviously)
