NVCAP // Basic Questions

Hello!

The Story before:

Since i have a few Problems with some Zotac GeForce Cards i tried making my own EFI-String for it.
The Cards i am talking about are the Zotac GeForce 9800GT 1024MB and the Zotac GeForce 9500GT 1024MB.
The Cards have the same Layout: VGA | HDMI | DVI

I got both Cards working with 10.6.4 with VGA-Output. QE/CI fully working.
I had the Cards working with NVEnabler 64 / GraphicsEnabler / GraphicsEnabler + NVIDIA.ROM/ EFI-String
but
The System will just give me output on the Display if i boot with VGA.
The DVI Port will only work if i boot from VGA, then connect DVI, and unplug VGA. Dual Display wont work with this.
Since i want to set up a dual (or even triple / if possible /) Display-Config it is kind of important to me that at least 2 Outputs work.

I made a Custom EFI-String based on the data i got from NVCAP (using a selfmade ROM-Backup) and it worked same as before. QE/CI working but only VGA-out and DVI with some "tricks".

So here are my questions about NVCAP:

- There seem to be two diffent styles of NVCAP Values

<key>NVCAP</key>
<data>BAAAAAAAAwAMAAAAAAAABwAAAAA=</data>
or
<key>NVCAP</key>
<data>04000000000003000c0000000000000700000000</data>

- Does it make any difference what style the values are in?
- Are they even a different Style, and even if they are, how do i convert them?
- Is there a NVCAP/EFI-String based workaround to get all Outputs ( VGA | HDMI | DVI ) working?


The main reason i need info on this is that i need at least dual-display support. The other Reason is that the GPUs are working way to slow (CineBench/OpenMark) when connected via VGA or DVI/VGA-Adapter.

If anyone got info to this, or any suggestions how i can get at least 2 outputs to work, it would be great if you could help me or just post a link to the solution.

The next thing i will try in a few days will be a HDMI to DVI Adapter, but if this works there is still the Problem with the slow VGA-out.

Things i have already tried are:

NVEnabler 64.kext >> QE/CI working / bad performance / VGA-Only
GraphicsEnabler=y >> QE/CI working / bad performance / VGA-Only
GraphicsEnabler=y + NVIDIA.ROM >> QE/CI working / bad performance / VGA-Only
EFI-String from EFI-Studio 1.1 >> QE/CI working / bad performance / VGA-Only
EFI-String Custom from NVCAP >> QE/CI working / bad performance / VGA-Only
GraphicsEnaber=no >> no QE/CI / VGA-Only
NVinject.kext >> no QE/CI / VGA-Only
Natit.kext >> no QE/CI / VGA-Only

Is there any other Enabler that could get Dual-Displays or even Triple-Displays to work?

Is this NVCAP valid?
<key>NVCAP</key>
<data>04000000000003000c0000000000000700000000</data>

Any suggestions or Solution for this would be welcome.

Thanks in advance!
