Issue 16: Geforce 8400GS - 512MB

Reported by Chris Story, Feb 19, 2010

I have an EVGA 8400GS-512MB (PCI-E) card that I can't seem to get 
working properly using the latest chameleon (from svn). The device 
id for this card, 0x10DE06E4, is present in the chameleon2 source 
code but the card is never detected. In fact, the VRAM size reported 
in System Profiler is 32MB. I was able to add an EFI string that I 
made using gfxutil and the card detected, but there seems to be a 
problem with screen artifacts when I use this method. 

Could this be an issue with the memory size on the card, or is the 
problem on my end?

Attached is the plist and hex file I used to generate the EFI-String 
that resulted in the card being loaded, but had screen artifacts in 
dashboard.

Hi! 
Same here on 8600 GT 512 mb 
but i solved the problem : 
i had to remove the GrapicsEnabler complete from 
com.apple.boot.plist and add the Efi Studio code into it.
it wont work when u set GrapicsEnabler=No and add the efi studio 
code.

Hi,
I have no problem with EFI string or DSDT code for my 8600GT 256MB 
and nothing in c.a.B.p other than arch=i386, but Graphics Enabler 
doesn't work for this card
this is my gfx.plist:

<key>PciRoot(0x0)/Pci(0x1,0x0)/Pci(0x0,0x0)</key>
