Re: ETA for nV GeForce GTX 675M w/2GB
There aren't any video-related options in the BIOS at all, unfortunately. I suspect you are right that the Quadro is just a different daughter card connected to the same hard-wired mobo. I've sent them an email to check.
I'm reading up on vga_switcheroo right now. It looks like a less kludgy solution than bumblebee.
I'll keep the thread posted with my discoveries...
