Hello 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

Tried 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.

Post your unedited DSDT here with your IOreg (From the IOreg app) and I will inject your GPU into your DSDT. I just need to know what frame buffer the card uses.

Also if you can not disable the onboard intel GPU it will never work... Sorry for the bad news...
