Congratulations,

To check QE/CI just play Chess from applications, a movie, a screensaver if it works then u have QE/CI.

By the way, Evoenabler works from /Extra/Extensions (my case) either 32 or 64 bit.

 

 

Thanks , I can certainly move pieces around, OK, so looks like it's all good. I'll checkout 64-bit, but need to sort out the networking which 'definitely' doesn't work in 64-bit currently.

OMG

WOOOOOOOOOOOOOOOOOOOOOO

 

It worked!!!!!!!!!!!!

Sapphire ATi 4850 512MB

 

>>>>

 

 

2. I downloaded Kexthelper and installed Evoenabler.kext and modified ATI4800Controller.kext

(I did this because I read in the digital_dreamer install thread that Evoenabler doesn't work in /Extra, as it's an x86_64 file and needs to be in /System, and as modifed ATI4800Controller.kext also showed as this type I reinstalled that.

 

4. reboot arch=i386

YAYAYAYAYAY Thank you soooo much

It seems you run the CHESS program in Applications, and as long as you7 can move the pieces it proves the hardware acceleration is working fine

I have 10.6.1 installation and Sapphire HD 4850 1024 Mb GDDR3 graphic adapter.

Please somebody help me, I'm going mad. Because with standard netkas QE_CI_Exotic_cards_10.6.1 package I can only boot in safe mode or normally but getting the final gray/black with white squares screen.

 

I tried to add my devid to ATI4800Controller.kext file but it didn't work for me. Still gray screen.

By installing both EVOenabler.kext and ATI4800Controller.kext I have had some problems using the safe mode.

Could it be ATY_Init.kext. Should I remove it? Can somebody share a working package for SL 10.6.1? Please ;)

For me all the files/kexts are original Native Snow Leopard files.

 

All i have then done is :-

 

1. Modify ATI4800Controller.kext and re-install with KextHelp

 

2. Download Evoenabler.kext and install with KextHelp

 

3. No other files (ATI_Init.kext or other packages) were required

ad 1: With what did you modified the ATI4800 Controller.kext? What did you inserted, etc..?

 

As documented in root post

 

 

 

Original :-

 

<key>IOPCIMatch</key>

<string>0x94401002 0x944a1002</string>

 

 

After Editing :-

 

<key>IOPCIMatch</key>

<string>0x94401002 0x944a1002 0x94421002</string>

Hello!

After installing evo and modifing the ATI4800 kext i reboot and it starts booting normaly and then black screen, monitor lose signal and pops a message from the monitor: Recommended resolution 1680x1050.

btw the hdd has activity!

 

is it possible that the drivers alredy have a custom resolution bigger than mine?

 

Thanks!!

this is what bugging me for a week now.

 

after i insert the extra key in ati4800.kext my monitor loses signal.

 

i've tried editing com.apple.boot.plist with <key>kernel flag</key><string>"Graphics Mode"="1920x1080x32"</string> but still i lose signal. I've tried evoenabler, deleting 4500 and 4600 ait kext etc etc

 

also -x doesnt work either. When i use "?video" at chameleon boot to see all the supported video type, 1920x1080x32 is there, all weird resolutions? :(

Hi all,

 

@muff : you also should install in your /extra directory the netkas LegacyATI4800Controller.kext.

 

 

I've got QE/QI working, my HD4850 is well recognized. But when I wake my mac after hibernation, I've got a video artefact ( blue images and mixed screen), I have to shutdown my system to restart it.

I also installed EVOEnabler.kext in /Extra.

 

Do I have to change something in the dsdt.aml file?

 

Thanks for your help,

i do have legacyAti4800controller in /volumes/OSX/Extra

 

but the resolution that osx uses 1920x1080 @60 hz is ntsc format? My montiro says it doesn suppor it.

 

Whn i use remote managment i tried to change to a different resolution, but no change. I hve my sapphire connected wih vi to a dvi input on my samsung 22 inche 1920 x 1080 monitor.

 

Is there a way for me to fix this?

How to run ATI Radion 4850 HD 10.6.4 x86_64 ?

 

On arch=i386 working 1920x1080@32

 

HDMI - No signal

(VGA-->VGA) The VGA output only works when the HDMI cable is pluged in, when I unplug it, VGA output stops working.

 

On x86_64 Kernel Panic ... :blink:
