Hello
I tested your dsdt,
Now it is not functional because if used
black screen
the AppleHDA kexts do not work
Why inject the HD2000 in your dsdt? For sound can be?
LEt when I try to use it, the HD2000 is not recognized correctly
is your say 64MB instead of 384MB
and no CI / QE
I tested on my E5420
Intel i5 - 2520
4GB of Ram
OCZ-VERTEX3
