Hi
i've been working with a Mac Pro 1.1 with 2 graphic cards for a while :
- NVIDIA GeForce 7300 GT (helper)
- GeForce GTX 260
Each connected to a different screen.
But since I upgraded to Lion, the 260 does not work any more, I can see it in the system info but nothing on the screen :

NVIDIA GeForce GTX 260 :

  Jeu de composants:   NVIDIA GeForce GTX 260
  Type:   Processeur graphique (GPU)
  Bus:   PCIe
  Logement:   Slot-1
  Longueur de la voie PCIe:   x16
  VRAM (totale):   512 Mo
  Fournisseur:   NVIDIA (0x10de)
  Identifiant du périphérique:   0x05e2
  Identifiant de révision:   0x00a1
  Révision de la ROM:   netkas.org
  Moniteurs:
Connecteur pour le moniteur :
Connecteur pour le moniteur :

Any ideas / guide how I could get it to work again ?

Thank you

Did you update to the 64 bit ATY_Init for Lion?

yes, dumb me, looks like he did

On that case, I would think that perhaps the problem may lie with that pesky "NVCAP" thing.

I think they have altered how this functions somewhat in Lion.

Or maybe he needs to see if his 7300 is still given 4 PCIE lanes?

Have a look at "Expansion Slot Utility" and see if perhaps this setting went bad.

The "Helper" card needs at least 4 lanes for trick to work.

I have the exact same issue as this guy. I bought my Card through ebay and having difficulties getting help from the seller. I'm coming at this blind - having not flashed the card myself, but I can't help but think maybe I can get it going myself. Any help would greatly be appreciated!

Yep. Tried that. No change for me. That is assuming that you just click and drag it into your system extentions folder overwriting the old one.

Can you post the screen shot again with new ATY?

There is something that should change from the shot you did before.

Hey, I just realized what I forgot.

You need to delete "ATY_Init896.kext"

I had created a custom version to report the RAM right.

It would nopt have been replaced by newer ATY_Init, in fact they are probably DUELING for control.

(Your screen shot should show 512 Megs of RAM unless Netkas got the "Auto RAM detect" working.)

Hi thank you for your help
here's the sys info :

NVIDIA GeForce GTX 260 :

  Jeu de composants:   NVIDIA GeForce GTX 260
  Type:   Processeur graphique (GPU)
  Bus:   PCIe
  Logement:   Slot-1
  Longueur de la voie PCIe:   x16
  VRAM (totale):   512 Mo
  Fournisseur:   NVIDIA (0x10de)
  Identifiant du périphérique:   0x05e2
  Identifiant de révision:   0x00a1
  Révision de la ROM:   netkas.org
  Moniteurs:
Connecteur pour le moniteur :

But it still doesn't work, but maybe I haven't installed the kext ATY_Init (July 22) the right way.

Could you explain the right steps to intall a kext ? I copied it in the extensions folder and used kext utility ...

What can I do to stop the cards DUELING ?

Thank you
