mosi Posted August 3, 2013 Share Posted August 3, 2013 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 http://db.tt/V5O2HJID which is obtained from this graphic bios http://db.tt/ZmNvJVEl 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 http://db.tt/2m7mwKJW for further reference: EDID from ubuntu: http://db.tt/7KBvztOY io registry from mac (with graphicsenabler=no as a flag) http://db.tt/dg6OEeon i followed this guidehttps://rampagedev.wordpress.com/guides/inject-your-amdati-graphic-card-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.

Slice Posted August 10, 2013 Share Posted August 10, 2013 I didn't insert your video but I corrected DSDT to be compilable. Your videocard seems to be \_SB.PCI0.GFX0 DSDT.aml.zip Link to comment https://www.insanelymac.com/forum/topic/290973-a-little-help-in-patching-dsdt-for-ati-dev_9555-framebuffer/#findComment-1938039 Share on other sites More sharing options...
