“I reply to myself, maybe some other is interested to know.. I finally have sound with a simple solution: I take back (from a snow leopard installation) 2 kext: applehda and voodoohda. Run kext utility and.. sound! I have tried that before, …”

“Great! Happy for you. For me I'm testing a new Lion iatkos 10.7.1 on a new harddrive. The problem is when I update to 10.7.2. No sound. Even if i use the old kext, still no sound. Can you please explain how you get audio for our alc890 ?”

“Hi everybody here, someone had try Lion on that system? Best!”

“today so many changes, but at the end, I have audio now! I have installed the voodooHDA from the Multibeast package, and voila': input and output analog and digital! Installed in System/Library/Extensions. Deleted any other audio like HDAen…”

“Update: i confirm my system can boot as before without NullCPUPowerManagement.kext. I just update the kernel with the X.6.3 from original apple combo update. Still no sound & sleep, all the rest work fine. Clavieramolette: I use articooling…”

“I forgot the temperature issue: my cpu about 45° never over 50, after 20 min of handbreake with full 8core load. best.”

“My bios is 2.30 and i agree that maybe my 2GB of RAM are not what your DSDT expect to see! Let's hope you can finally work at your best, without that only theory.. About NullCPUPowermanagement I agree, but for sound still do not understand.…”

“Wow 12gb of ram! Congratulations! Actually I have just 2GB.. hope to improve the ram soon. About your Boot.plist, do you think the string " Kernel Flags -force64 GraphicsEnabler=Yes " is correct? I have nothing in kernel flags and graphics …”

“adrian, what kind of kernel are you using? I just drop the mach_kernel from the empirecd.”

“Great! Are you using all core or just one? I only need a DSDT for that.”

“Hi, I have ONLY Legacy HDA with 6 other kext that I need. In order to build a mkext file, I have used MkextTool.app. Than I have manually put Extension.mkext file on the extra folder. Still no sound. I have also try to boot with -f, still n…”

“In my case, still no sound. LegayHDA and DSDT from page 3, but no way. Maybe some other kext in the extension folder need to be removed?”

“Ok, can you please confirm what kext I need for audio? LegacyHDA, LegacyAppleHDA or some other? Thank you.”

“hi adriangb, i have now all working in 64bit with x.6.3. But, audio do not work.. even if i put your attached files: DSDT and LegacyAppleHDA. Off course I have HDA enabler also. Why ? For the atheros - i7 problem, I have connected my fonera…”

“Restart and shutdown fixed, I'm still not understand why my audio do not work, with Hda enabler and legacy HDA... ?! by the way, I can use the system even if, the 2 BIG not solved problems are: WiFi (only one core working) and Sleep. Actual…”

“ok, understand for atheros I have read about new iMacs with i7, they have also some problem, so let's hope in some solution, as it's very frustrating boot with one core only... with this machine.”

“Adriangb thank you for your work, waiting for your sleep progress and dsdt-tutorial. Concerning atheros the problem is that is some way the IO80211family.kext do not accept multicore (or multithread) as the new cpu's do. I'm not able to fin…”

“just to report that I'm on a working X.6.3. I have followed a different way, using the EFI partition as boot. I have used the terminal just to mount the EFI on the desktop, than every files manually. I think this Munky can be still interest…”

“I get that error with all asereBLN boot-loaders, but chameleon. About kext I have only the 4 kext you suggest. In order to boot without prompt cpus=1 ecc.. can I put some text in the boot.plist?”

“Ok, about DSDT I have your with out CPU alias. Now, after Asere BLN119 install, I have the same situation as before. I post the picture, maybe you understand better than me..”

“now I have a new interesting situation. After soo many try, i have bee able to boot my X.6.2 using chameleon rc4. But only if at the boot I promt: cpus=1 busratio=20 arch=i386. The boot process is very speedy, about 8-10 seconds. Off course…”

“Adriangb, I have re-write a new com.apple.Boot.plist file, as you can see from the attached file. But at the boot, off course I need some kind of bootloader. How to proceed in order to boot with out the Empire CD? Or: how to install ASERE B…”

“There is a way to rebuild a new .plist? That's because i have accidentally deleted the original one. At the moment my config is X58 with Chameleon 2 on a first drive. On the second I have X.6.2 but i can boot with the Empire CD inside only.…”

“well, I can boot with the Empire EFI CD only. It's possible for you to adjust the .plist so that I can just use? I do not know AsereBLN's booter. If you have any suggstion is welcome.”

“Stephen.Eidson thank you for the help, actually I have some trouble with the boot.plist file, I think my need some more command. Best”

“Adriangb definitely, can you post again your Extra folder? I think the only two differences from your configuration, are video and Wifi. Anyway thank you for your helps!”

“I have finally a S.L. X.6.2 installation on my second drive. Sound is working and also wifi is recognized. My only BIG problem is that I need to use the Empire efi CD, without no way to boot. My step by step install from the first X.5.8 dri…”

“Adriangb, can you write a list of all kext for our board? Concerning the DSDT.aml actually I use DSDTSE ver.1.2. The point is that I'm not sure if that progr install the DSDT in the extra folder of Chameleon or just in the root.”

“Hi. Actually no way for me to use snowleopard, i can only start with iAtkos x.5.7 with one core only. In order to have all cores working I have deleted alias from my DSDT but I was able to start one time only with all 8 cores enabled. Can y…”

“"You'll need to use GraphicEnabler=Yes or an EFI string." how you suggest to do that? Can you please post your spec? I actually use iAtkos v7 with asrock X58 extreme, i7 920, 9500GT. I'm trying with Snow, do you have any suggestion? Again t…”

“Great! Do you think I can use your DSDT for my system? The only difference is the Graphic card, s I have the 9500GT. Thanks!”

“Thank you so much for your last post! I have a EP35-DS3R board and I have almost killed myself getting it to work with SL and your dsdt did the trick. I now have working ethernet, audio, USB ports and I no longer have to use NullCPUPowerMan…”

“I'm a bit confusing regarding kext and locations of them. By the way, as soon I would like to try a new SL install on a second drive. Some one here have been success with sleep on this board? Tks”

“about sound, no way for me. I have your last DSDT and the kext you post attached, but no. I can have audio only if i install Voodoohda.kext but only i I boot in cpus=1. I have DSDT at the root and all kext in the extension folder. No extra …”

“I have found the wifi-crash soltution. Maybe some one interested because it seem that a lot of people with atheros-based PCI card are experiencing problems. Now from an old post, I found the IO80211Family.kext from a 10.5.1 iatkos DVD, the …”

“Hi, yes I'm using your last posted DSDT. Now I'm finally found the problem I have with all cores enabled. When I use airport enabled, the system crash. I think can be some kind of atheros kext, but if you have some suggestions I appreciate.…”

“Ok we can wait your vacation for the GUIDE! Concerning your indications, are you referring to SL or X.5.8? Just because I'm quite happy with 10.5.8, the only point is to be able to use all cores, off corse.. Right now I'm using your DSDT, a…”

“Hi adriangb, why you do not write a quick guide with kext and DSDT, for Asrock x58 extreme users? I think that can be very needed from the most part of us. For my case, I'm only able to start with 10.5.8 with 1 core and busratio 20. With 8 …”

“Two separate drive 500”

“That's my com.apple.boot.plist”
