About This File
For Mountain Lion DP2 - OSInstall framework and OSInstall.mpkg patched so you can install on hard drives with DOS MBR-style partition tables, instead of GUID. board-id check is also removed, so no requirement is needed in an smbios.plist.
Tested and works just fine.
Just unpack to the root of the Install media?s volume with sudo. Example:
sudo tar xzvf ~/Downloads/MountainLion_DP2_MBR_Patch.tar.gz -C /Volumes/Mac\ OS\ X\ Base\ System
Or graphically unpack with Archive Utility and drag and drop. I just always show the command line method because it reserves the original root:wheel ownership. bleh.
