Hi,

I'm trying to get an NVidia K3000m Kepler/gk104 graphics card working in a Dell Precision M6700.

After installing the 10.8.2 update for later 2012 macs, the NVDAStartup.kext seems to get the GPU recognised... and it detects that it has 4 display ports, but the displays aren't initialised.. This is the same as trying to get the HD4000 going too.  The driver sees the IGPU, but doesn't initialise the displays.. but anyway, the K3000M is the important one.  Optimus is disabled in the BIOS...  I've included the text ioreg dump with the NVidia driver half loaded..  If anyones interested in taking a look.  I'd be happy to try out DSDT edits if anyone has suggestions..  I suspect it's a question of injecting the right values.. or waiting for a new driver..

Thanks.

PS. I also posted a question about this here: http://www.insanelym...w/#entry1877698  Which has a bit more info about what I've tried.

OMG!  I think all the problems I was having were due to having Direct IO (VT-d) turn on in the BIOS.  I disable it and now HD4000 is working..  I'll write more when/if I get the K3000M going.

Before disabling VT-d.   The machine would boot in safe mode with HD4000 and K3000m.   But when booting in normal mode weird stuff would happen.  Like partially initialising the graphics system.  I would often get things like this in the log file

Which looks a bit like the CPU or memory is duff.
