- I'm trying to dual-boot W7 and 10.8 on a GA-Z77X D3H/i3570K.

- The i3570k has integrated Intel HD4000 graphics, and I also have a Radeon 7850, which is not supported. I'd like to use HD4000 for OS X.

- I've set the BIOS to keep the HD4000 on at the same time as the 7850 (checked since Virtu MVP recognises both in Windows).

- When I take out the 7850, the HD4000 works fine, but when the 7850 is installed, Chameleon will go for that instead. I have set the BIOS to prioritise the integrated graphics, but that hasn't stopped Chameleon from going for the 7850 and hanging.

Now, I've looked through some of the Chameleon documentation, and was wondering if there's a way to specify which graphics chip it uses. I assume what happens now is that it scans for available devices and is ignoring thee BIOS setting. Is there any way to stop it from doing this?

Any ideas would be much appreciated!

Hi. I found this info http://www.insanelymac.com/forum/topic/282631-hd3000-other-card-solution-by-efi-string-creation/ a while ago and worked for me. I have a GA Z77X-UD5H + 2500K and a HD7850.

Now I'm looking some way to use my HD 7850 in the OSX 10.8.3 and get rid of cable switching an VirtuMVP.  :)
