Download iAtkos Lion, burn it on a DVD/restore it to your USB stick, follow on-screen instructions, select the following at the customization screen:
Install, then boot with -v GraphicsEnabler=No busratio=20 (if you experience some sort of Kernel Panic boot with this extra flag: arch=i686), if you encounter any other problem, boot with rBoot LE CD -v GraphicsEnabler=No busratio=2
SpeedStep in Lion:
*from previous post*
1. Follow those instructions SpeedStepper including the MSRDumper kext (LOAD IT FROM THE TERMINAL DO NOT INSTALL IN EXTENSIONS)
2. Set SMBios to MacBookPro8,2 - you can mess around with others and see your results
3. Make sure /Extra/org.chameleon.Boot.plist has the following flags
<key>GenerateCStates</key> <string>Yes</string> <key>GeneratePStates</key> <string>Yes</string>4. Back-Up and delete Sleep/NullCPUPowerManagement kexts
5. Copy SSDT.aml from archive to Root partition *see bottom of the post*
6. Reboot, use -v flag pay attention to
kernel: AppleIntelCPUPowerManagement: Turbo Ratios <number> kernel: AppleIntelCPUPowerManagement: initialization complete kernel: AppleIntelCPUPowerManagementClient: readythis means AICPUPM got patched correctly and you should have ST working.
I made 2 SSDT files:
-9TS-SSDT.aml.zip uses 9 turbo states like real MBP 8,2 that allows your CPU to reach its max (2.9GHz) but if you are a heavy user like myself rendering and other stuff, this version is not good if you care of your laptops life span because it automatically goes to the max. Keeping it under heavy load most of the time heats up the CPU to 80ºC with no cooler pad. (Also included in pack)
-3TS-SSDT.aml.zip uses 3 turbo states, so your CPU doesn't go to it's max TS (2.9GHz) unless there is a hard core application demanding it so the CPU heats up to only around 60-65ºC (which is better than on windows either way). The CPU will run under average conditions with a TS of 24-26 unlike the 9TS version which would go to 2.9 even from opening youtube. (Also included in pack)
Install the one you want by simply copying it to your root partition (where OS X is installed)
I have installed the iAtkos L2 on my XPS 15 with the customized options. The only thing I could not choose was the 11.0.0 GM Kernel because it was not on the list.
1. Is that because of the L2 version? Should I take L1? Or is L2 alright too?
After installing I booted with rBoot and -v GraphicEnabler=no busratio=20 into my installed Lion.
The system boots but the graphic is of course slow and horrible. I guess now I have to install the kext files.
I can't come further at the Speedstep in Lion.
2. Is that what I have to do next?
I don't know how to include the MSRDumper kext in SpeedStepper and (LOAD IT FROM THE TERMINAL DO NOT INSTALL IN EXTENSIONS).
Can somebody help me?
Thanks in advance,
