Question

Booting into verbose leaves be at what the attached image shows

Using cpus=1 GraphicsEnabler=No or just graphicsenabler=no goes to the apple logo then tells me to reboot

PCIRootUID=0/1 tells me an error with my Nvidia graphics(630m)

try booting using a hdmi or vga external display(both)..ive had semi success on a i7 toshiba lappy...i had both vga and hdmi connected at the same time to 2 monitors,this let me boot into osx lion successfully albeit other issues then need to be sorted...

i dont know why this combo worked, but think this may trick the graphics to switch because it senses a signal on the video ports.

What I am wondering is if the hardware in the mac's is different, that the HD4000 outputs to the screen and the nvidia outputs to the screen and if this is possible in our laptops. If we were to turn of the HD 4000 will the nvidia take over and output directly to the screen like a mac or will this not work because it is made to first go through the HD 4000. This is just a little though of mine and it is purely theoretical.

EDIT. This might be a handy tool to check what is working http://www.macupdate.com/app/mac/33905/gfxcardstatus

It also seems that you can turn the card switching on and of in os x

EDIT: http://support.apple.com/kb/HT4110. It seems that if you turn off the graphics switching it will only run on the nvidia card. So if we were to switch this off and then install the drivers or install the drivers in safe mode and then turn of the switching this might actually work as the HD 4000 will not be used.

EDIT again (sorry guys): My first "horror" theory witch would make it impossible for us to use the nvidia card isn't true. It says: "The architectural changes through Arrandale and an ongoing lawsuit that has forced Nvidia to halt the development of future chipsets have required PC manufacturers like Apple to rely on proprietary Intel chipsets and their integrated graphics processors." This is good news for us because that means it is possible. However apple does not use optimus but its own system so I think our best bet (if the driver patching doesn't work) is do disable the internal graphics in os x so it is forced to use the nvidia 6xx cards (which should have compatibility when we install the normal drivers). Only down side is that if you would want to switch to the HD 4000 you would have to remove all nvidia drivers and such. So if you would want so switch back to the nvidia card you would have to do the entire process again. This is once again theoretical as I have not tested this nor will I be able to test this very soon. That's why I'm hoping one of you guys can test this. Let me know if this doesn't work, then I will see if I can get an adjusted BIOS where we can manually set the graphics card (I hope I don't have to do this because it will be hard if not impossible to do).

Sorry guys once again a little edit: If the setting in osx doesnt turn of the HD 4000 (it should but just in case) this program will show you what card you are using and lets you set which card you want to use. http://gfx.io/

Little update on my personal work (noting special really). I got ML installed on a external hdd (can't find the internal one (aj fixed this) using the boot flags: cpus=1 GraphicsEnabler=No PCIRootUID=0 -f -x -v. @Aj Hope the work on the tutorial is going well.

Seems like they added support for the GT 630m. {censored} Forum ? Information

Update: I will be testing the Broadcom BCM94322HM8L as soon as it arrives to check the compatibility (should be native) (http://www.amazon.com/dp/B002OB0FPI/). Note as I can't get this one shipped to where I live I ordered one off ebay http://www.ebay.com/itm/300778771732?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649#ht_3697wt_906
