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)
DSDT obtained from ubuntu
for further reference:
EDID from ubuntu:
io registry from mac (with graphicsenabler=no as a flag)
i followed this guide
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.
