Attempting to patch DSDT for 9600M GT support

[chris7519]

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:

                   Method (_DSM, 4, NotSerialized)
                   {

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.
