Cool, congrats! :)

Do you have any problems with colors?

I don't remember which connectors I patched in that kext to be honest. Pithecia has only 2 of them, so probably you won't have VGA port, only HDMI. On the other hand, if you want to use VGA, better switch to Lion. In ML I noticed some weird system crashes when changing resolution with mirroring on VGA screen enabled.

That DSDT wont work for him. Only identical motherboards can use the same DSDT, he will get a kernel panic.

 

HI all

 

can somebody help me with my 6470m gpu. i try ati6000controller here nothing change,

I can't compile my dsdt.aml give me an error with dsdtse.

I upload my dsdt Ioreg vgabios edid and original Ati6000Cont from iatkos ml2.

 

thanks in advance

Thats not the vgabios of the AMD gpu, it's the Intels instead, I dont exactly know how to extract the AMD one if you have Intel and AMD, wait for Trucker MK's answer

 

Edit: Try this way:

1) Download GPU-Z, select AMD gpu in the bottom.

2) Then press on the chip button with a green arrow on it

Hi Trucker MK,

 

Thank you so much, with second method I could see QE enabled screen on HDMI output with monitor.

I am using HP Elitebook 8570p which as AMD Radeon HD 7570M.

I used your attached 10.8.3_GE_ATI6000Controller.kext.zip file with Chameleon_boot_v2.zip boot file

 

It shows black and white stripes on my main (laptop) screen and I guess this is because of the difference between 6650M and 7570M (7500M/7600M Series)

I see 7570M model's device ID is 0x6841 (Thames) where as 6650M's model ID is 0x6741

Any suggestions for this?

 

Thanks for your help!

The difference is that one with backlight works correctly and the one without it - with 16bit colors :D

BTW, I have a feeling that even when my monitor works with normal color, refresh rate is a bit lower than in Windows. Doesn't make as much difference as 16bit color though.

You are welcome, guys i realy don't like repeating this every time someone asks me about other than the 6650M. I need VBIOS, DSDT and ioreg output is very useful. Without these i can't say anything. I need to check if your GC is included in Chameleon or even we can try the DSDT patch, but i need those things first.

No, that's just the clamshell hack "Device (PNLF)" which i have in my DSDT. Clamshell hack = AppleBacklightDisplay, without it = AppleDisplay. Tried it both ways, no changes.

 

This solution should in theory work in 10.9 without any problems?

I hope it will.
