Method (_DSM, 4, NotSerialized)  // _DSM: Device-Specific Method                {                    Store (Package (0x06)                        {                            "hda-gfx",                             Buffer (0x0A)                            {                                "onboard-1"                            },                             "layout-id",                             Buffer (0x04)                            {                                 0x1C, 0x00, 0x00, 0x00                            },                             "PinConfigurations",                             Buffer (Zero) {}                        }, Local0)                    DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))                    Return (Local0)                }

Not wok, try to patch HPET:

Name (BUF0, ResourceTemplate ()                    {                        IRQNoFlags ()                            {0}                        IRQNoFlags ()                            {8}                        IRQNoFlags ()                            {11}                        IRQNoFlags ()                            {15}                        Memory32Fixed (ReadWrite,                            0xFED00000,         // Address Base                            0x00000400,         // Address Length                            _Y10)                    })
