Recommended Posts

Hello.

 

I have problem with my new build. 

 

Asus X79 Deluxe (0403 BIOS) - http://www.asus.com/Motherboards/X79DELUXE/

i7 4930K (Ivy Bridge-E) - http://ark.intel.com/products/77780/



 


 or      u n i b e a s t     and myhack. 

 


 

All methods have same result. After sucessfully install (only with -v cpus=1 npci=0x2000) I boot from USB and after kext loads screen give me only black screen. (Kernel issue?)

 

Please if you have any tips... Thanks!

I think it is a gfx issue. Have you tried to boot with graphicsenabler=no and possibly added flag -x?

 

You should have a look into the amd gfx-card hardware section.

 

Have fun.

Hi 

Toooorch,

 

I have the same motherboard and CPU as you but a different GPU, however I'm experiencing the same problem. Did you ever resolve it? If so, it would be most appreciated if you would not mind sharing.

 

Many thanks,

Koo

I've got a:

 

Gigabyte GA-X79-UP4 (rev 1.1) bios F4

i7-4930x

GeForce 610

 

I ran into similar troubles. Solved with:

 

-v -f -x cpus=1 npci=0x2000

 

try GraphicsEnabler=yes/no with various cards as well as PCIRootUID=1 if the above doesn't work.

I noticed that with the USB installer, my card wasn't recognized without GE=yes looking at the text on the screen but once it loaded into 10.9 all worked.

Adding -x is what finally did it. Alternatively you'd need to remove a whole bunch of unneeded kexts from the installer.

Hi Toooorch, 

 

I am facing the same issue, also -v -f -x cpus=1 npci=0x2000 didn't work. Using [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url], I got a successfully installation by putting the mach_kernel in the root dir of the USB and using:

 

-v npci=0x2000 cpus=1

 

After the reboot I get to where it passes the boot flags and it just gives a black screen.

 

My Build:

 

i7 4930k

Asus Sabertooth x79

32 GB RAM

 

I will look into this some more and get back to you. If you find anything out please share.

boot to single user mode with -s switch!

 

at the command prompt give this commands line-by-line

fsck -fy
mount -uw /
mkdir /kext_backup
cd /System/Library/Extensions/
mv AppleIntelHD* AppleIntelSNB* ATI* GeForce* NVDA* /kext_backup
reboot

now you removed the all Graphics related kexts, you will have to boot your mac normally (in 1024x768) without graphics driver. ;) Good luck!
