Hi everyone,

For all those having problems with Geforce 8800GT 512 MB , here are the files that will make your card work fully. After struggling for two weeks , these kexts works flawless. Here is the link to the kexts. Just install using kext utility and set Graphicsenabler = yes

DOWNLOAD


Hurray , I got this finally working on my PC. Please let me know if the kexts works for all. :angel_not:

Hi Sharon,
I'm going to try your kexts, However I have this card... info from bdmsg....

GeForce GT 230M 1024MB NVa5 [10de:0a28]-[103c:7001] :: PciRoot(0x0)/Pci(0x3,0x0)/Pci(0x0,0x0) device number: 1

GeForce GT 230M:

Chipset Model: GeForce GT 230M
Type: GPU
Bus: PCIe
Slot: PCI-1
PCIe Lane Width: x16
VRAM (Total): 1024 MB
Vendor: NVIDIA (0x10de)
Device ID: 0x0a28
Revision ID: 0x00a2

If your kexts don't work, what would the line in the kext be for my card ?

EDIT

They didn't work ......

@peter_sm, the above files are specific to Geforce 8800GT , You just need to inject your device id in all more than one files in the zip, just replace "0x061110de" everywhere in the kexts with your device id.

  <key>IOPCIMatch</key>
  <string>0x061110de&amp;0x0000ffff</string>

Seems correct !


0A28 = "NVIDIA GeForce GT 230M"
0A2A = "NVIDIA GeForce GT 230M"

Not sure .. which is 1024 MB .. try both and see which one works

Just inject your Device ID in NV* kexts properly, it works. I was also struggling with the same issue from last 2 weeks before I got it solved. Just device ID inject worked perfect. and also make sure you have set graphicsenabler = yes. The Kexts I posted are 8800GT specific sop will not work on any other card.

@shaorn

What do you mean with "

Just device ID inject worked perfect"



Is that the way I was doing? or is it another way to do this ? ;-)

And I'm using

graphicsenabler

=Yes

Cheers everyone for your help. Only just got round to testing tonight and I have just used the nv kext from DP4 as suggested and this is now all good.

Actually that might have been a thread I am on. I had to remove the NV stuff in my DSDT also in order to get my graphics back.

Hold the phone. My 8800GT works in 10.8 flawlessly. OP, which brand 8800GT do you own?
