Radeon HD7770 Boot no qe/ci

[spongemak]

I manage to boot mountain lion with HD7770 in vga mode, seems like the mac mini profile made the trick, can someone guide here? maybe this is a solution for people with HD7xxx series.

Here are my specs:
Gigabyte Z77X-UD5H
XFX Radeon HD7770
i7 3770k
HD4000
16GB 4x4 Corsair Vengeance 1600

I disabled GraphicsEnabler and used HD4000 gfx string injection in my org.chameleon.Boot.plist, couldnt boot until I changed to Macmini5,1 profile.

Guide what? It's an unsupported card...

Yes I know, but it is possible to boot mountain lion with this card, this can be helpful for people with 7xxx series.
