Nvidia driver does not work.

 

Last one I tried: 10.8.5, with myHack installer. Boot options don't seem to change the outcome. I either get a blank screen or get stuck at the verbose boot.

 

 

Could it be related to BIOS settings or a hardware issue? I recently upgraded the machine to 30GB of RAM, could it be related?

 

I'm trying various BIOS settings. Nothing changes. BIOS is F4D.

 

Also interesting is that the linux nvidia driver does not work either. Nouveau driver works.

 

The video had worked for a good while on 10.8.0, BTW. 

 

I couldn't try the windows driver. Because I couldn't install windows 7 on a GPT partition.

 

Could a DSDT help? How can I debug this issue, can anybody help me please? I am at a loss!

Pandora and Kakewalk installers with 10.8.5.... same problem continues.

 

NVDAGF100HAL loads successfully, then either blank screen or freeze,  for any boot flags!

Ok, this is a mega silly behavior.

 

I swapped the card with my old GT 240 and it works on 10.8.2... just like that. Only GTX 480 is borked.

use flags GraphicsEnabler=Yes PCIRootUID=1,2,3,4,5 for the gtx 480 the reason is due to roms/memory on gfx card

No... Another case of not understanding what Boot Flags actually do...

 

 

 

Driver issue with the installer are to blame. On the USB installer remove (and backup) the Nvidia drivers from SLE. Then install with:

 

-v npci=0x2000 GraphicsEnabler=No

 

Then post install reinstall the drivers and boot with:

 

-v npci=0x2000 GraphicsEnabler=Yes

i see no point in giving him a flag for pci config begin for a gfx issue also i tested on several users with PCIRootUID flag i gave z77 x58 x79 example the 470 used the uid of 4 please show me a post where the npci flag fixed a gfx issue thx
