I thought that my HD6770 would work fine on lion when the correct kext where installed.
But it doesn't. When booting with GE=Yes, is stuck at some apple.core.services.authentication time out. (or something like that.)
After reading a lot on the internet, if i want my card to work with lion, i need to flash it to an HD5770.
Which is risky, and since i use it in windows for gaming, i dont want to downgrade my card.
Ive also added the device ID of my card to the info.plist from the needed kexts, but no difference.
Then i found this post:
there's a way to have HD 6770 recognized on Lion but not without sweating !
you need to compil chameleon ( i let you search ) with this file : branches/Chimera/i386/libsaio/ati.c - Chameleon Svn Source Tree - Chameleon open source boot loader project.
Up to you !
I would love to do this, but how?! can anybody explain this?
Or maybe even do this for me?
