Gigabyte U2442N Ultrabook


Specs are:


Intel Core i5-3210M CPU @ 2.50GHz (Ivy Bridge)

Intel HM77

Intel HD Graphics 4000 (0x8086 (0x1458))

Realtek ALC269

nVidia GeForce 640M

Intel Centrino Wireless-N 2230


BIOS: U2442.F0A


Working: LAN (Realtek) using Lnx2Mac RTL

Not working: Intel and Nvidia, Touchpad


So far I have created a USB install using ###### and Mountain Lion (10.8.0)


I have installed to an external USB drive and then updated to 10.8.1


I have used [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] to make the HDD bootable and also created a DSDT.aml


The issue I have is that if I boot normally, the boot hangs on "nVidia GeForce GT 640M 0MB NVe7 [10de:0fd2] :: PciRoot (0x1)/PC1(0x1,0x0)/PC1(0x0x0x0)"


There is no option to disable the nvidia GPU in the BIOS.


Has anyone gotten any idea how to disable it using DSDT.aml? Or could I enable it somehow to get it to work? I would prefer that.


If I boot with -x -v GraphicsEnabler=No I can boot into X.


If I boot with -v GraphicsEnabler=No it then hangs on "NTFS volume name...". I tried deleting the nvidia KEXT but now it wont boot any further anyway.


I haven't tried deleting the Intel ones, presumably I need those.

Thing is, NullCPU is installed! I just tried removing the NV* Kext's and it boots without safe mode.


I don't have HD4000 working. I still get the message about AppleCPUIntel timing out.


I'm guessing I need to inject ig-platform-id but I can't find the specific thread about it.

I am in the same place as you are with u2442n. I am trying to get it out of safe mode. It boots in safe mode and everything seems to work except touchpad and wifi.


I got an external wifi adapter and have wifi working.


I am wondering if a dsdt can help with booting in regular mode.


Can you provide yours?


I am using Clover bootloader in UEFI mode.
