chris7519 Posted September 4, 2009 Share Posted September 4, 2009 I have NVDarwin and a patched DSDT.aml (via DSDT Patcher GUI) and my 9600M GT currently runs fine. However, I am attempting to patch the DSDT for full support without the need for injectors. I just started my DSDT patching journey yesterday and I feel completely lost. I felt as though I was one step closer when I saw that the nice folks at EvOsx86 team released DSDTSE. However, with my noob skills, I wasn't able to enable graphics support even with the laid out Hacks provided. It simply seemed like a matter of copy and paste into the right section, but I encounter total blackness after the splash screen. The suggested hack is as follows: Nvidia Laptop. Locate the graphic section of your DSDT (laptop/mobile) Example: (PEGP), it could also be AGP or IGP or something similar. (Use the ACPI search feature to locte the section, or "Registry Info" from the menu). Device (PEGP) { Name (_ADR, 0x00010000) Method (_PRT, 0, NotSerialized) { If (GPIC) { Return (Package (0x04) { Package (0x04) { 0xFFFF, Zero, Zero, 0x10 }, ......... the code continues............... We place the hack just below of the following: Device (PEGP) { Name (_ADR, 0x00010000) Device (GFX0) /* <-------------------------- Hack Begins */ { Name (_ADR, Zero) Name (_SUN, One) Method (_DSM, 4, NotSerialized) { Store (Package (0x1A) { "@0,compatible", Buffer (0x0B) { "NVDA,NVMac" }, "@0,device_type", Buffer (0x08) { "display" }, "@0,name", Buffer (0x0F) { "NVDA,Display-A" }, "@1,compatible", Buffer (0x0B) { "NVDA,NVMac" }, "@1,device_type", Buffer (0x08) { "display" }, "@1,name", Buffer (0x0F) { "NVDA,Display-B" }, "NVCAP", Buffer (0x18) { /* 0000 */ 0x04, 0x00, 0x00, 0x00, 0x00, 0x00, 0x01, 0x00, /* 0008 */ 0x06, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, /* 0010 */ 0x00, 0x00, 0x00, 0x00 }, "NVPM", Buffer (0x20) { /* 0000 */ 0x01, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, /* 0008 */ 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, /* 0010 */ 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, /* 0018 */ 0x00, 0x00, 0x00, 0x00 }, "VRAM,totalsize", Buffer (0x04) { 0x00, 0x00, 0x00, 0x20 /*<----------- Ram Amount: 0x40 = 1024mb, 0x20= 512mb, 0x10= 256mb */ }, "device_type", Buffer (0x0D) { "NVDA,GeForce" }, "model", Buffer () { "Nvidia GeForce 8600M GS 256 MB" }, "rom-revision", Buffer (0x20) { "DSDT ROM v.1a #irc.osx86.es ©" }, "reg", Buffer (0x78) { /* 0000 */ 0x00, 0x00, 0x01, 0x00, 0x00, 0x00, 0x00, 0x00, /* 0008 */ 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, /* 0010 */ 0x00, 0x00, 0x00, 0x00, 0x10, 0x00, 0x01, 0x02, /* 0018 */ 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, /* 0020 */ 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x01, /* 0028 */ 0x14, 0x00, 0x01, 0x42, 0x00, 0x00, 0x00, 0x00, /* 0030 */ 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, /* 0038 */ 0x00, 0x00, 0x00, 0x10, 0x1C, 0x00, 0x01, 0x02, /* 0040 */ 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, /* 0048 */ 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x02, /* 0050 */ 0x24, 0x00, 0x01, 0x01, 0x00, 0x00, 0x00, 0x00, /* 0058 */ 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, /* 0060 */ 0x80, 0x00, 0x00, 0x00, 0x30, 0x00, 0x01, 0x02, /* 0068 */ 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, /* 0070 */ 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x02, 0x00 } }, Local0) DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0)) Return (Local0) } } Here we can change the name: Buffer () { "Nvidia GeForce 8600M GS 256 MB" }, Here the NVCAP: "NVPM", Buffer (0x20) { /* 0000 */ 0x01, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, /* 0008 */ 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, /* 0010 */ 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, /* 0018 */ 0x00, 0x00, 0x00, 0x00 }, Here the Ram amount of the card. "VRAM,totalsize", Buffer (0x04) { 0x00, 0x00, 0x00, 0x20 /*<----------- Ram Amount: 0x40 = 1024mb, 0x20= 512mb, 0x10= 256mb */ }, I inserted the hack in the same location but no dice. I'm looking for suggestions of either what I did wrong or maybe pointed in the direction of a thread which includes someone patching their DSDT successfully for graphics support and showing how they found the needed information and where.
