**UPDATE** New video here: https://www.youtube.com/watch?v=JvclT7gdArg (you will still need to follow the instructions on this video if you do not know how to flash.)

This is how to flash an ATI Radeon X850 Pro/XT card for use on Mac. Things you will need:

Graphiccelerator: http://thomas.perrier.name/software/Graphiccelerator-1.3.4.dmg.zip

OSXvnc (Vine): http://downloads.sourceforge.net/project/osxvnc/Vine%20Server%28OSXvnc%29/Version%203.0/VineServer3.0.dmg?r=http%3A%2F%2Fsourceforge.net%2Fprojects%2Fosxvnc%2F&ts=1369586326&use_mirror=superb-dca2

Chicken of the VNC (Mac): http://downloads.sourceforge.net/project/cotvnc/cotvnc/Chicken%20of%20the%20VNC%202.0b4/cotvnc-20b4.dmg?r=http%3A%2F%2Fsourceforge.net%2Fprojects%2Fcotvnc%2F&ts=1369586399&use_mirror=iweb

VNC Viewer for Windows (32-bit): http://www.realvnc.com/download/get/1293/
(64-bit): http://www.realvnc.com/download/get/1295/

My reduced ROM: http://www.mediafire.com/?k7hjm67373wv9v4

The full ROM (try flashing this one first): http://campahunta.free.fr/Downloads/ROMs/ati_oem_x850xt_108_agp_full.zip

Note that this does NOT work 100% on the X850 Pro (as seen in the video), it will however work fine on the X850 XT.

X850 Pro Stock ROM: http://www.techpowerup.com/vgabios/699/ATI.X850PRO.256.Samsung16_050208.rom (right click link and click "Save as".)

X850 XT Stock ROM: http://www.techpowerup.com/vgabios/615/ATI.X850XT.256.Samsung16_050119.rom (richt click link and click "Save as".)

(Note... Only use these ROMs if you did NOT run the dumper and backed up your original ROM first, also do NOT use them on a card produced by any other manufacturer than ATI.)
