If you install x86 then chose BIOS.fd from x86 folder) - Open CMD, run command "cd C:\PMPatch" - Patch bios, run command "pmpatch C:\PMPatch/BIOS.fd C:\PMPatch/patchedBIOS.fd" - Rename patchedBIOS.fd to BIOS.fd and replace for the original once in "sk1wv360\os2012321a_360\Madrid20R20RG_BIOS_WIN_V360\ x64 \ BIOS.fd " (pls take note x86 or x64) - Flash your bios: run InsydeFlashx64.exe in "x64" folder (or InsydeFlash.exe in x86 folder).
