i tried lot's of guides and different methods to get full advantage of my probook 4520 graphic but this mobility radeon hd 4300/4500 still not working.

i tried adding dev id to kext. tried EDID, tried adding it's framebuffer from vbios to shrike in kext.

this is my last try.

i want to add this framebuffer which is already replaced in ATI4600Controller as shrike

which is obtained from this graphic bios

and i wanna patch it to this DSDT:

DSDT obtained inside mac (with graphicsenabler=no as a flag)

http://db.tt/dwCAHBpE

DSDT obtained from ubuntu

for further reference:

EDID from ubuntu:

io registry from mac (with graphicsenabler=no as a flag)

i followed this guide
https://rampagedev.w...rd-into-a-dsdt/

 

the main problem is when i compile original DSDTs it shows lots of errors! and i can't patch! meanwhile i am really not sure where to add codes for GFX!

any help would be really appreciated.

I didn't insert your video but I corrected DSDT to be compilable.

Your videocard seems to be \_SB.PCI0.GFX0
