How to add GPU into DSDT to get rid of graphics enabler=yes

 

At this point on my oldest mac build I am almost done. In my plist I only have kernel cache, quiet boot, and graphics enabler=yes.

 

I was wondering if you could add the framebuffer some how so that graphics enabler=yes is not needed. Thanks.

Sure it's possible, I don't have a code example for a 4850 but you can probably adapt the code from my 6870 to some extent, or at least use it as an example...

 

Device (PEG0)
           {
               Name (_ADR, 0x00030000)
               Device (GFX0)
               {
                   Name (_ADR, Zero)
                   Name (_SUN, One)
                   Name (_PRW, Package (0x02)
                   {
                       0x09, 
                       0x05
                   })
                   Method (_DSM, 4, NotSerialized)
                   {
                       Store (Package (0x0E)
                           {
