flashed 7900GTX to quadr fx5500 efistring

[jediha]

Hi,
I used the 5500.rom from this forum to flash my NVIDIA7900GTX card. It's now a quadro FX 5500 card. Flashing went well, works great in win7. I've a dual boot machine (AMD opteron 2.7 dual processor, 4GB rAM) with snow leopard 6.0 (HAZARD version).

I generated a EFI string in OSx with the GFXUTIL script and inserted it the com.apple.boot.list .

When I restarted I got dual screen and good resolution. But the system was almost like thick syrup. Everything goes reaaallly slow. And my mouse pointer moves almost uncontrolable.

Can someone or can you(aquamac) give some support or right directions. I read somewhere that generating the EFI string in snow leopard was no good because snow gives the wrong PCI string??

Anyway, here is my PCI string from the graphic board and the generated EFI string:

PciRoot(0xb)/Pci(0xe,0x0)/Pci(0x0,0x0)

How are you getting to boot into osx with your 5500? I can't even work on my EFI string because I can't get into the system.

Where did you download the .rom from whenever i try to download it from (http://www.s155158671.websitehome.co.uk/nvidia512cardrom.html) I get a message as follows (Forbidden
