RadeonHD 4850 and Leopard, finaly!

using 10.5.7 beta ati drivers (jsut five kexts) and new natit, i got my 4850 working in 10.5.6 Leopard :)

You need to have OSX 10.5.6 or higher

What’s working – qe/ci, resolution change

What Problems:

currently only second dvi port works for me, and only with dvi-vga adapter

also, Display is recognized as standart vga/svga display, so only 4:3 resolutions available

only usefull for VGA connections –  with switchresx(before using it, make sure u can change resolution) help i added 1680×1050 mode jsut fine :)

EDIT3(for4850): booted with dvi2vga(converter only, no monitor attached to it) in second port, and dvi connected to first port(closest to mobo), and voila,

display on first port properly recognized.

some vertical little screen jerkness sometimes

Pkg with drivers  you will find in #radeonhd room on irc.osx86.hu

User with 4870 reported he has almost no problems with 4870, he just cant change resolution, results in black screen

Btw, 10.5.7 kernel also supports Nehalem i7 fully now.

P.S. I hope no other company than Apple/AMD will pretend they wrote drivers for 4850/4870 or nehalem i7
