Asus EAH6850 modified ATI6000Controller.kext

Recommended Posts

I've modified the ATI6000Controller.kext to get the HDMI and second DVI ports working. I've only tried two combinations (HDMI & DVI-I; DVI-I & DVI-D). The DVI-I (upper port) works with DVI and a DVI-VGA adapter. I have not tested the DP. My computer couldn't boot with the other modified kexts for the EAH6850 that have been posted on the forums.


This is the first time that I've done something like this, so if I've mucked up something, let me know so that I can fix it.


My system is a ######/###### non-DSDT installation on a GA-Z77X-UD5H. I have ATIConfig=Duckweed and ATIPorts=4 in my plist.


The modified Duckweed personality info:


00 04 00 00 04 03 00 00 00 01 00 00 12 04 04 01

00 08 00 00 04 02 00 00 00 01 00 00 22 05 03 04

04 00 00 00 14 02 00 00 00 01 00 00 01 02 05 06

00 02 00 00 14 02 00 00 00 01 00 00 00 00 06 05

I'm not sure I understand you. Do you mean using the personality in order to be able to install ML with a 6000 series card? I doubt it. I haven't used the card or the personality for an installation of ML. I never had any trouble installing Lion with it, but this modified kext will only work with ML.

So if I use an EFI VBios for HD 6xxx cards, then I can pass the white screen?


Have you seen this?



Although it said only works on real macs, I think maybe UEFI+Clover can get it work too.


No, EFI has nothing to do with Hackintosh's but it has to do with a real Mac. Your are just over think it. DSDT injection and then placing the DSDT in your extra folder on the install USB will get you around the white screen without removing drivers. But really why is this a issue when you only install once or twice and then you are up and running 100%...


Also clover has nothing to do with this either. You are not understanding what each app and item is doing...

Might be a bit late but I own a 6870 and to get pass the white screen installer I just simply put my system to sleep and then wake it and then I'm presented with the normal installer screen. I was contemplating on flashing the vbios but said meh I'd just leave the card alone.


But yeah, you could try the sleep and wake and see how it works out. Found the topic a bit late though.
