GA-B75M-D3P with 660 Ti booting problem solved.

[VideoLasVegas]

This is a system with a 3570k cpu and 32gig of ram running Mountain Lion 10.8.2 It would hang on booting past the Apple logo screen on the white screen when i tried to boot using the MSI GeForce 660 Ti card. It would boot fine with the native Intel 4000 built in DVI port. I first tried changing graphicsenabler=no in Multibeast 5.2.1 but that didn't fix it. I next did searches on the forum and suspected that my "system definition" wasn't correct. After changing that to iMac 12,2 - it fixed the problem and it is booting fine.

Hi, I have a problem here and I hope that you can help.

I'm running Gigabyte B75M-D3P and GTX 660 OC, both with latest BIOS, and just cannot boot into clean install of OS X 10.9.1 problem seems to be in graphics.
Can you send me photos of you bios config, please?
I've got Xeon E3-1230v2, so no IGP=>no access to OS X GUI either way.

Thanks.
