ATY_Init for 6870.

Tested it myself. what works:

  • minidp ports, active and passive adapters
  • hdmi port
  • upper dvi port
  • dvdplayer/geekbench/steam

what doesnt work:

  • second dvi port
  • dvi->vga adapter on upper dvi port, for vga displays you will need active mdp->vga


  • dl-dvi on upper dvi port, dl-dvi should work via apple’s minidp->dl-dvi adapter tho, the adapter was tested to work, dl-dvi wasn’t

To install it you need this ATY_Init and ati drivers from 10.6.7 update for newest imacs.

MacPro users – this will not work, for macpro bios of 6870 need to be embeded into Info.plist of aty_init.

To use with Lion, Β install framebuffer (atiframebuffer, atisupport, ati6000controller kexts) from that imac update.

    Have problems with 6870 and Aperture 3.1.3.
    As soon as I apply any brushes to any photos, it gets look like it use 8-bit palette.
    All worked well while I was using GeForce 8800 GTS.
    I think Aperture uses video card to process images via core image and has some problems with that card. But Core Image Fun House works well without any problems.
    Any suggestions?
