I've tried this and other many ways, but the problem is that my card it's no been recognized by the OSx. It recognize it on the boot, but when the system is loaded up, only the Intel HD graphics is active. I can disable the Intel HD on the BIOS, for what I've goggled there's no way of setting the Intel as discret.

With the intel I can do much, I cant even watch a video on youtube with this card. It sucks. I must install Windows 7, cause I work with photography and video and can't be without good VGA performance. A real shame because I loved Lion, this week as been so much fun playing with it.

A real shame.

Hey guys, I have Lion 10.7.4 installed on a Hp Dm4 1095br with a ATI Radeon Mobility HD 5450 1gb .. but there's no way I can make the OSX load the ATI Kext files.

On a verbose book I can see that it recognizes the card just fine, but when the system is up I only have my Intel Hd Graphics GPU working.

I tried to disable the Hybrid video in mi BIOS but it's a locked function, even if I switch off the Hybrid, goes back on automatically.

I don't know what else I can do, I've search this forum like crazy and no solution so far. Hope you guys can help me.

I finally got into the Advanced settings on my Bios, but I can't disable the Hybrid Graphics function. Even if I change the option, falls back to Hybrid automatically. I've tried at least 10 different solutions found here on the forum and another forums, and anyone got my ATI card recognized. I know that the bootloader recognizes it because it shows in the boot ATI CARD POSTED, but the osx can't recognize at all.

Yes. the injector is in place, the kexts too. But as I said, it's like the ATI card didnt existed. It doesnt show up in the System Info and the kexts doesnt work.

There is a way to force the system to see the Ati? I saw in other post that a guy used a .rom file, and in the chameleon there's an option to use a ATI Rom, but I have no idea how to do that.

I'm actually using the Intel HD kexts, but even if I delete the intel kexts will not recognize, and I end up with the Intel HD with only 64MB of video.
