No Prob
Its just a few things that arent working, but i will update it as the drivers become available, & im gonna wait on on installing 10.5.7 because my USB stops working if i update for some reason.

Anyways glad you found it helpful!

robsie you are the best. I tried osx86 a few months ago on my s6965 and couldn't for the life of me get it to work. Do you have any ideas for the graphics card? Im gonna try adding the device and vendor id into the .plist and I'll let you know if you haven't already tried it

Have you got the media keys working with iTunes rob?

Hey, Sorry for no reply, I havent got the media keys to work, The Vol Up & Down Are the only ones that work, but i did get the Graphics card to go to native resolution i updated my post above. Now all we need is full graphics card support this only lets you change the resolution, but its a start.

kewl im about to try it right now.....i think this is the one that gave me the black screen though....where did you get this one from?
