derperoo replied to derperoo's topic in ATiTried that unfortunately! The card is not detected at all. I think I am making progress on a custom DSDT to fix this... will post here if I have success.
Hello all, I have a HP Envy 14t-1200 CTO which has an i5-460m with integrated graphics, and ATI Radeon Mobility 5650. OS X does not detect the 5650 at all, and the integrated graphics are not supported. The BIOS is very limited and does not provide the option of switching the primary graphics card. My question is has anyone disabled the integrated graphics and set the discrete to be the primary through DSDT editing? Thanks for any help! Derp
derperoo posted a topic in ATiHello all, I am fairly new to this whole thing. I am attempting to get the ATI Radeon Mobility 5650 working on my HP Envy 14t-1200 CTO, but OS X Mountain Lion (installed via ###### after deleting some IntelHDGraphics kexts) does not seem to detect the card. The BIOS on this computer is very primitive, and I am unable to disable the integrated graphics there. What are my options to make this work? Would a custom DSDT be able to force OS X to notice the existence of the Radeon card? Can anyone point me in the right direction? Thanks very much, Derp
