Notes

• Type the following after boot, "KernelBooter_kexts"="Yes" "CsrActiveConfig"="103"

Kernel Extraction

• Install Pacifist on OS X.

• Mount "InstallESD.dmg" file.

• With Pacifist browse to the above volume (use the "Open Apple Installers" menu option) and then open "Essentials.pkg". Extract the folder & file (Kernels/kernel) located at /System/Library/Kernels/kernel location.

ISO Creation

• After extracting the Kernels folder, place it in the same directory as the iso creation script.

• Run the ISO creation script, making sure to use 'sudo' if possible.

• Copy the ISO from your Mac to your KVM machine.

Enoch Bootloader

• Download Enoch bootloader from http://www.insanelymac.com/forum/ (requires registration).

• Using Pacifist open the “Enoch-rev.####.pkg” file and extract the file called "boot" from Core.pkg/usr/standalone/i386/boot

• Rename boot to enoch_rev####_boot.

jar -xf <zipfile> is pretty neat.
