MAC OS X Lion USB installer error

[Vahagn-Doc]

I'm trying to install Lion on my Dell N5110

 

Specs:

CPU: Core i5 2410M

RAM: 8GB

HDD: 500GB (GUID), 2 Partition (Windows 7 + Mac OS X 10.6.3)

 

I followed this tutorial: http://www.insanelymac.com/forum/index.php?showtopic=256729

 

So I run the installers "Extra Lion" and "Chameleon RC5". Also I copied

> disk_label

> boot.efi

> kernelcache

> mach_kernel

> MacOSX_Media_Background.png.

files to the root of a USB Drive and placed DSDT.aml into Extra folder. Without DSDT.aml it just restarts after loading kexts.

 

but when I try to boot from USB it gives me this error.

 

My DSDT.aml dsdt.zip

Maybe my DSDT.aml is wrong???

Try to add

<key>GenerateCStates</key>
<string>Yes</string>
<key>GeneratePStates</key>
<string>Yes</string>

into "/Extra/org.chameleon.Boot.plist" (or "/Extra/com.apple.Boot.plist")

 

If that not works, then try to copy NullCPUPowerManagement.kext into "/Extra/Extensions/":

NullCPUPowerManagement.kext.zip
