ASUS 4850 512 MB DDR3 /0x94421002/ 2 DVI

RAM : 4 GB

HDD : 1 TB in AHCI mode

The installation is OK. After reboot visible the apple and when activate ATI card then screen will be black.

Steps:

1., Overwrite ATY_init.kext by newer

2., copy LegacyATI4800Controller.kext into System/Library/Extensions

3., delete System/Library/Extensions.kext
