I will try to explain. I have multiboot Windows/Linux/OS X - two versions: with classic and stable Mavericks and newish El Capitan . In the slot PCI E2 inserted GTX 950, in the slot PCI_E4 - GX 650, Win, Lin and Capitan work fine with both cards, but for Mevericks, I have to pull out 950 to boot with GTX 650, so I would like to turn slot with 950 off and drag the display to 650 card. So I decided that method to patch DSDT.
MaLd0n, thanks I will try.
Ok, PCI_E2 completely disabled in mac (if I boot with integrated graphics), but if I try boot with GTX 650 white screen appears while loading login screen
Maybe disable PCI_E4 slot and rearrange video card from it to the PCI_E2 or somehow swith to nvidia while booted with integrated graphics?
Upd: Finally got it working! lilu+whatevergreen switch my video and picture login screen appears! Now Maver fully on 650. Thanks again.
