nVIDIA Quadro 2500M (DevID x029a)

[scrotty]

NOTE: The Quadro 2500M is based on the Go 7900 GTX, I think.

 

I have tried just about everything to get QE/CI running with my nVIDIA Quadro 2500M notebook graphics card under Leopard.

 

What is working:

Full resolution (1920x1200)

Full memory (512MB)

 

Tried "just about everything" includes:

- *Reading every forum post I can find on the subject*

- using various NVinjectors (NVinjectGo, NVInstaller)

- using no injectors, but EFI Strings instead (using EFIStudio)

- various versions of Leopard (10.5.2, 10.5.4)

- various versions of NV* and GeForce* kexts

 

But no matter what I do, I can't get QE/CI to show as "supported" in the System Profiler.

 

The one thing I have not tried is flashing the ROM on the card. But, from what I've read, that's really only for memory issues - not QE/CI. But I could be wrong about that.

 

So a couple questions to anyone who can offer some guidance:

1. Can a Quadro 2500M utilize QE/CI in Leopard?

2. If so, can it be done without flashing the ROM?

3. If the ROM must be flashed, does anyone have any pointers?

4. Do I need to try to flash the card as a "7900 GTX"?

5. Would doing #4 be super dangerous?

 

I would so appreciate any advice!

I'm very impatient. I went ahead and flashed my 2500M to a 7900 GTX. It worked! Under 10.5.2 I now have QE/CI, full resolution, and full memory. And, you can see here, my DeviceID changed from 0x029a to 0x0299:

 

 

Now the next hurdle - doing the 10.5.3 combo update and 10.5.4 update. We'll see if QE/CI stays...

I did lose QE/CI immediately after applying Kalyway's 10.5.3 combo update. But I followed Krazubu's advice and set the IOProbeScore to 0 in my injector. Again, QE/CI is back!

 

Now up to 10.5.4...

Doubt your still around here, but THIS IS KILLING ME..

 

 

i've got a m90 w/ the quadro 2500m i had been running with qe/ci on my old 10.5.7 but can't replicate it in 10.6.

 

any help would be greatly appreciated.
