Hi,Thanks for tips. The problem with dsdt is that I could not compile dsdt last time so Mald0n compiled it for me. So even if I inject for alc272 there is no gurantee that I can re-compile it successfully. However, sound was working flawlessly in OS X Lion. Can I use the same kext for ML? If I have to use dsdt injection, can you give me a link of dsdt injection tutorial? Have you also tried to connect your computer with TV using HDMI? IF yes, how did you manage it? I get black screen after connecting HDMI cable with TV. sorry for asking lots of question.

Hi artur-pt, It seems we have same configuration in our computer. My sound isn't working after installing Mountain Lion. I too have Alc272. How did you manage it to work?Also, I used unishit method to install ML but wont recognize my graphics card. Graphics card run fine with Chameleon after internal lcd forced edid. My Elantech trackpad works fine when I boot using unishit USB but wont work when booting through Chameleon!!! I copied all kexts from Extra/Extension folder from unishit to Chameleon but no success? any suggestion?

Solved using "Internal LCD Forced EDID" and by using chameleon 2.1svn-r2003. Now need to fix trackpad and sound. Suggestions are welcome. I have Realtek ALC272 sound card. Broadcom Netlink Gigabit Ethernet BCM 5788 (Devicd ID 14E4:1692) Elantech PS/2 TouchPad

Hi, I installed Mountain Lion. I have ATI Radeon HD5470 512MB Now, I am getting only 1024 x 768 resolution with 3 mb video ram. While using 'kextstat', I can see 'AMDRadeonAccelerator', 'AMDSupport', and 'AMD5000Controller' kexts loaded. I had no problem with graphics issue in Lion but not getting proper resolution now. I'm using unishit USB installer to boot and during boot, I can see it identifies my card as ATI 5400 family card. I tried to use chameleon "Enoch-rev.2042" but got scrambled desktop so couldnt login. However, while booting through chameleon, it identifies as correct graphics card during boot up. I can see one of the staff has same card like mine. would be very happy to get your advise. Thank you.

Thanks mald0n. I will try and let you know. Hope for the best.

hi, Thanks for the reply. Actually, I am trying this for almost a month now. If my graphics card does not work then it is very difficult to use Lion. Are you using the same ATI kexts that comes with Lion or did u use some other kexts? what about DSDT? I can boot my computer without DSDT too but does not know if the problem is due to DSDT or not? Which Chameleon are you using to run your Lion? Hope to hear from you soon.

hi, My laptop is: Acer eMachines E730G Intel core i3-350M, 3GB DDR3, 320GB ATI Mobility Radeon HD5470 512MB Initially, I get 8 errors but after clicking 'fix errors', I do get only 1 error. The error says "Invalid object type for reserved name(found Zero requires Package)". I have installed Lion 11A51 with working wifi (atheros), sound (VoodooHDA), batterymanager but not graphics. I am using usb mouse coz my trackpad (Elan tech) does not work but its ok. The only problem is due to my graphics card. It did worked once but after restart it didn't work. I tried many things but in vain. I think may be it is due to my DSDT. I even did EDID injection. Interesting thing is that when I boot with Chameleon 1083 (using usb drive), I only get 1024 x 768 resolution with 3 mb but when I use Chameleon 752, I do get 1366 x 768 resolution with 4 mb memory!! I really don't understand what is the problem here. Anyway, I would highly appreciate if you take a look on my DSDT. I extracted this DSDT in my Windows 7 system. I have installed Lion in another partition DSDT.zip
