Is it possible to use the HD3000 through the motherboard to drive one monitor and a PCIe graphics card to run a second monitor?

I have a Gigabyte Z68XP-UD3 (using MacMini system definition) which has an HDMI output on the motherboard only (comes with an HDMI to DVI adapter). I also have a GeForce GT210 video card with HDMI, DVI, and VGA. (I know I can't use the VGA.)

I can use one graphics source or the other, but not both at the same time. When I set the BIOS to use the PCIe as the primary an Onboard always on, the system doesn't even see the HD3000 in the System profiler. If I set the BIOS to use the Onboard as the primary, right between Chimera loading and the grey Apple loading screen, I get a flash of
ERROR: dcbtable_version is 0x3
ERROR: nvidia ROM Patching failed
The system boots fine after that, and in System Profiler it sees both graphics sources, but when you click on the nVidia the specs aren't correct and it isn't even trying to use the card.

Is this even possible to use both simultaneously? Seems like it should be, but I'm newish at Hackintosh and haven't tried this before.

NOTE - I do realize that I can use the DVI and HDMI on the nVidia at the same time to drive two monitors (which I am currently doing), but I just don't like the way the HDMI signal looks on my monitor, which has a native HDMI input. Smaller text is very pixely. I would use that HDMI to DVI adapter so as to send it via DVI, but there isn't enough room on the card to plug both in at the same time. If I had a short HDMI pigtail extender I could probably pull it off, which I might explore.
 
Pretty much having the same issue/question. System recognizes the HDMI video when operational, however no graphics output to the HDMI just to the discret card.
 
Works on my board when HD3000 is patched in to dsdt and onboard is set as primary graphics. It's funny to run Cinebench on that combination since OpenGL results depend on which screen it is running at.

Please, do tell how you patched in the HD3000 to the dsdt for us semi-noobs?

I stand corrected. Thanks for solving the problem and sharing. By the way, install this AppleHDA.kext http://www.tonymacx86.com/viewtopic.php?f=16&t=45413, set dsdt/HDEF/layout-id to 0x85 0x01 0x00 0x00 and reboot to HDMI audio on both displays as well as 889 onboard audio.

Thanks, I did have HDMI audio working at some point but since I don't use onboard audio at the moment I haven't bothered with keeping AppleHDA.kext updated.
