Mod Bios installed and build info updated
I've successfully installed ML and updated to 10.8.2, but it works only with the integrated graphic card With the gtx 480 he keeps show me the black screen after the loading screen (verbouse or not) I've read that ML have same problem with the voltage of the Fermi gpu...
