[Help]White Screen After Boot

[KavinZhao]

I have OS X 10.10 installed on my Dell Precision T5400 Workstation.

If I boot with -x flag it works all right. But if I don't it stucks on white screen with a cursor(can move) when it is supposed to show the login screen.

 

Previously the OS X 10.9 works fine.

 

I have:

Intel Xeon E5410 x2

Nvidia Quadro FX 1700 PCI-E  (no built-in graphics)

Samsung SSD

 

Someone says that is is a problem of my graphic card driver, but I don't know which kext is causing the problem. I removed all AMD kexts.

 

I have Windows installed but it is on another disk so it shouldn't be the reason.

 

Any ideas?

 

And P.S. I use Chameleon Bootloader

find the Vendor-ID and Device-ID of your "NVIDIA Quadro FX 1700" and thus patche the NVDAFG100HAL.kext, perhaps you still need to create an EFI string and submit these EFI string in your org.chameleon.boot.plist (see example) possibly generating in additional a ROM-file of your graphics card and add the ROM-file in the /Extra/ folder. how to do that, just google.


here's an example:

    Yes
    VBIOS
    Yes
    device-properties
    device-properties
