Knowndragon replied to Pontus Carlsson's topic in OSx86 10.8 (Mountain Lion)Hey I might have some info that would help. Try using this AtiPorts=? how ever many ports you have. AtiConfig= your cards name. Also I did manage to get this fully functioning with a amd 7950. I am not too proud of the way I did it and really it don't even matter how I did it but it is done.
