zoliky Posted January 21, 2013 Share Posted January 21, 2013 Hi, I added this code to Device (GFX0). I need it for AppleHDA. Â Method (_DSM, 4, NotSerialized) { Store (Package (0x04) { "hda-gfx", Buffer (0x0A) { "onboard-1" }, "AAPL,snb-platform-id", Buffer (0x04) { 0x00, 0x00, 0x01, 0x00 } }, Local0) DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0)) Return (Local0) } Â After adding that code, I'm getting a lot of DSDT errors. I would like to mention, it's a RAW dsdt of my HP4540s laptop. The only thing I added is HDEF and that patch posted above. I'm stuck and need your help, please. I attached my DSDT. I would be very grateful for any suggestion! Your time is appreciated. HP4540s-dsdt.dsl.zip Quote Link to comment Share on other sites More sharing options...

zoliky Posted January 21, 2013 Author Share Posted January 21, 2013 DTGP is already in the file, at the end. The problem is something else. Quote Link to comment Share on other sites More sharing options...
pernacabeluda Posted January 21, 2013 Share Posted January 21, 2013 There is probably a method _DSM in scope GFX0 already. You can remove it, or inject the properties in EFI string (device-properties) instead of DSDT.
