News about Radeon 3870/3850 and OSX.

One of guys got 3870 card, so we started testing

So far we can’t get working framebuffer, ATY_Lamna.kext and ATY_Hypoprion.kext make

blue screen without mouse (but at 1680×1050, so fb works but then freezes) .

And about QE/CI,  patched ATIRadeonX2000.kext to support 3850/3870 is ready.

But this kext need working framebuffer (for noobs, framebuffer means u can change

resolution and etc) otherwise u will get distorted screen with symblols like “?”.

I posted here natit.kext for 3850/3870, with it u will need ATINDRV.kext from

leopard build 9a527.  It’s enough to start trying to get working framebuffer.


To try other framebuffers than ATY_Franklin.kext, change all Franklin words in 3800

entry, to Other framebuffer name (like Hypoprion or Lamna or Iago)  3 times.

Good luck, and this is not for noobs.

    Will you be doing anything to bring regular power management to the HD3870 cards under OSX? They run 100% all the time no matter what you are doing.
