@ Jon lachonis Well

AppleIntelSNBGraphicsFB.kext and AppleHDA.kext both need to be installed with kextuutilty.app other wise they will not work.

Secondly reasons for distortion issues can be many things, presence of nvidia kexts, intel gma 950, intel gma x3100 and intel hd kexts. Just remove all unnecessary kexts also remove ATI kexts. After deleting these kexts u need to clear the kernelcache. Then simply run kextutility.app it will generate a new kernelcache for the existing kexts. Just follow the guide exactly without skipping any steps.

By the way do u have 1920x1080 or 1600x900 resolution ? i have added 1920x1080 as default screen resolution in org.chameleon.boot.plist, if u have smaller resolution please change it accordingly.

Frankly speaking its not recommended to use i7 DSDT and SSDT on i5 processor. In i7 DSDT the code includes 8 cores where as i5 has 4 cores and in SSDT the p states differ due to difference in processor speeds. But with rapid development in chameleon boot loader v 2.1, We no longer need SSDT in the root of the lion partition. Just make sure u have enabled generate P states= yes generate C states= yes in org.chameleon.boot.plist and then u can delete SSDT with confidence.

I will patch ur i5 processor with applicable patches, Can u please post ur i5 DSDT.aml or DSDT.dsl generated with the help of DSDTparser DSDTEditor_Linux_Windows. Please post the vanilla ( i mean original DSDT without any modifications, patches) DSDT. Also please post the hardware details of ur laptop, i mean sound card is it ALC 665 or some other), do u have optimus ? As i need to know what i am patching.

@ RDGnome

U need to format ur hard drive to MBR not GUID partition. One more thing i would recommend u to install lion on the same hard drive where Windows 7 is installed in order to mitigate the problems. Just shrink ur current Windows 7 partition and install lion on it.


Great thanks! This is the raw DSDT.dsl, I did not attempt to compile or error fix it at all. I had some problems compiling it before, I wound up commenting some lines per your instructions.

I really appreciate you taking the time to do this. Here are my specs

Dell XPS 17 L702x X17L-3333ELS
i5-2430M 2.4GHz processor
1GB NVIDIA® GeForce® GT 550M graphics with Optimus

The audio seems to be working fine, so I'm guessing this is 100% compatible. I wasn't able to find any listing suggesting that there was a model with a different sound card.

Also, the bus ratio for the process is 24 so I've adjusted that as well as the res in org.chameleon.boot.plist.

@ Jon Lachonis

Well u have attached my i7 DSDT instead of ur i5 DSDT, Have u generated DSDT from Lion or Windows 7 ? if ur running the DSDT Parser from Lion, make sure delete DSDT.aml from the root of the lion partition and then run the DSDT parser app, otherwise it just picks the DSDT.aml from the lion partition ( which is my i7 DSDT).

If ur running the DSDT parser from Windows 7, just make sure there is no other DSDT.aml or DSDT.dsl in that drive, also check the folder of DSDTEditor-Linux-Mac-Win just remove any DSDT's from the folder and then finally run the app and generate the DSDT.dsl.

Mahesh I resinstalled and the good news is that I know have a boot loader when I boot :)
However, The resolution problem still stands. It really shouldn't be happening.
Funnily enough, in chameleon settings in system preferences, I took off graphics mode and my resolution dropped to 1024x768. Graphics enabler doesn't do anything either..
Please, I am begging you, find a solution, I even have wifi working! So close to the perfect Hackintosh!

EDIT: I have found the solution!! My XPS 17 is a 3D version so has no Intel integrated graphics! Thats why it isn't working. And seeing as I deleted all the Nvidia kexts I'm going to have to reinstall for the 5th time :(
Cheers

@ RDGnome

Can i know ur screen resolution and laptop specs ? U are not suppose to use graphicsenabler if u have optimus, it should be used only when u have 3d screen.

Have u removed all unnecessary kexts and have u cleared the kernelcache ? And then install

AppleIntelSNBGraphicsFB.kext and then install latest chameleon v2.1 bootloader and restart, it should activate graphics acceleration with QE/CI ( then it automatically switches to the native resolution of the laptop)


Update:

Check this thread http://tonymacx86.co...pic.php?t=23185 , as my guide will only help people with no 3D screen.

Screen resolution: 1920x1080
Laptop: Dell XPS 17
CPU: i7 2630qm
GPU: Nvidia GT 555m 3D 1920 x1080
RAM: 6GB
2 HDDs.

Should I reinstall or is there something I can do now to allow me to get full resolution based on the facts that have just emerged?
Thanks

Strange. I have deleted all instances of dsdt.dsl from windows, and it still seems to be generating an 8 core cpu reading. Do second gen I5's have 8 cores maybe? Regardless, here is one pulled from my windows after removing all appearances of DSDT.xxx

@ Jon Lachonis

Check this thread http://ark.intel.com...Cache-2_40-GHz).

Intel core i5 2430M is a dual core cpu with 4 threads. So it should show 4 cores cpu0, cpu1, cpu2 and cpu3 in the DSDT not 8 cores ( cpu0, cpu1, cpu2........cpu7). I dont know why u are not able to extract ur OEM DSDT.

I tried to follow that thread but its a little confusing.. I'm not so sure what to do and I don't want to mess anything up.
What BIOS do you have? I'm assuming A12, but I just updated my BIOS to A16. Will I be able to still use your resources with A16 BIOS? Just because the other method seem soo complicated when yours is so simple..

Thanks

I have 2670qm 1920x1080 10gb ram. I do have the 3d display. so I've got graphicsenabler=yes with gf1000 kext.
I've followed the guides with success everything seems fine. but i have a low geek bench score of 7449
http://browse.geekbe...ekbench2/572154
any suggestions would be appreciated.

thanks

Sorry I just read your earlier posts and realised your a few steps behind me. I also did a clean load for the 5th time. this time I also selected the gf100 driver and added GraphicsEnabler=Yes to my smbios in the extra folder. I agree with you, the tonymax guide is very confusing, I tried a A16 dsdt from there and it left me with no USB or sound. Overall this guide has worked perfect, minus the graphics bit. But my system appears to be a third slower than its supposed to be???? I found someone with a similar problem and he was advised it could be a speedstep issue. So I'm going to update to 10.7.3 and try the powermanagement kext he was given.

I'll try that. So you can use this dsdt with the A16 BIOS? If you can I'll be happy because I was very close to getting a great Hackintosh.

WOOO HOOOO Geekbench score 10404
My bad, I forgot to delete Nullcpupowermanagement.kext.
so just to recap: if you have a 3D L702X, follow this guide but also pick gf100 driver, don't delete Geforce kexts and add GraphicsEnabler=Yes to org.chameleon.boot.plist in the extra folder.

Oh and Ive updated to 10.7.3

@ RDGnome, Jupitersmoon

Well please dont use my DSDT as it has dual Graphic cards ( Intel HD 3000 & Nvidia GT 555M) code. Where as 3D screen has a single Nvidia graphics card.

Please use StarbuckSteves A.16 DSDT & kexts and use my guide if it works for u.

sorry i just saw your post. i don't seem to have any issues at the moment. have you looked at starbucksteves post it has 47 pages. I tried his a16 dsdt, that was the one that stopped my usb and audio from functioning.

i am just stating it as a precaution, if something goes wrong please don't account me. Well 3D Screen DSDT code is different from Optimus DSDT. Specially in the Graphics or video card sections, if some conflicts arises then it might reduce the life of ur laptop. So be careful.

Can u send me ur Laptop DSDT or steve's DSDT, i will patch the DSDT. Preferably ur own vanilla DSDT.

Jupitersmoon, Do you choose the gf100 kext when installing? And do you follow the intelsnbgraphicfb.kext steps?
Cheers

Mahesh, Are you trying to patch the dsdt to suit our laptops? That would be awesome cheers.And what is a vanilla dsdt?

Hi. After some trial and error, I believe I have the vanilla DSDT for the i5.
