Thanks for sharing! Is that on your GA-G31M-ES2L rev:1.x, or another computer's DSDT?

 

dell inspiron 1520 ..

 

on the g31m i changed _ADR 1 to 0.. has _UID allready down 3 lines from _ADR

 

also if i use macbookpro 3,1 or 4,1 i loose wifi and lan. i think its the way MCHC handles through smbus the pci-e depending if windows.

 

if i use macbook5,1 (not pro) or 6,1 PRO i get good graphics loading time ( no beachball on safari) and wifi and temps are good.. some people report no speedsteps with plain macbook4,1 but wireless works.

 

i suspect the pci bus addressing or ram changes a little when osx osid in dsdt.

 

i added a empty Device (MCHC) with _ADR 0 under pci beginning but it doesnt load AppleMCCS*** (something i saw in graphics nvidia driver ioreg of real mbpro4,1)

also the mbp4,1 uses RP03 , 5, 6 .. my inspiron uses 1, 2, 4.
