Necessary Kext for booting the Installer
NullCPUPowerManagement.kext
FakeSMC.kext
Voodoo
PS2Controller.kext
11.Make a Org.Chameleon.Boot.Plist with following
If you are HP user like me then simply Add cpus=1 along with kext-dev-mode=1 for botting OS X to avoid Kernel Panic related to LocalACPI
12.Create the new folder name as “Kernels” on the USB/System/Library/ and place your kernel here
OSInstall.mpkg replace to
/System/Installation/Packages/OSInstall.mpkg
OSInstaller replace to
/System/Library/PrivateFrameworks/OSInstaller.framework/Versions/A/OSInstaller
Note:-Always boot with kext-dev-mode=1 to use unsigned kext like above
