Finally!

I found out, that doing things in the right order sometimes helps ;-)

After flashing the vBios in the first post in this thread a clean install of the NVidia-Drivers was needed - and suddenly everything (including Display Port and laptop display) work fine.

My mistake was, that I flashed the vbios over and over, but there was no automatic detection of the activated diaplay port.

So thanks a lot svlt7 for providing help and bios!

I've bought it in the bay from eurocom as a special upgrade kit for the m15x, but the bios says DELL. I am confused - Is there any way of determing, who manufactured it, so I can search the net for an apropriate vbios?

Yeah, the GHz and OC edition are based on the Dell vbios, not the best idea to flash such a vbios on your card.

The vbios in my thread isn't a Clevo vbios, I just named it Clevo in order to show that it should be flashed on a Clevo card, I haven't tested a different 660m... I only got one from mxm-upgrade and was tweaking and testing until I found a way to get the internal screen working, DP was working fine for me, not sure what the problem is in your case, might be a slightly different board revision.

When nvidiainspector shows Dell then it's probably looking at the IDs of the board and not the cards IDs, e.g. if you go to the device manager the IDs will also show up as Dell.

So I have got a DELL card - but a newer revision, right? Is there any other Keppler bios around which might fit (650m, 680m)?

Hi,

thanks a lot for this guide. Especially the hint with the copper shim...

I have still got a question though...

I have been fiddeling around with the vbios of my card:

- the card (eurocomm) had an original vbios (see attachment)GTX 660m_org.zip, where - as you said - only the vga port works and the laptop display stays black, though NVidiaInspector says it is a DELL card...

- I was able to flash the card with the Clevo 660m rom provided in your guide. Result: the laptop display works, but the display port has no signal - the vga port neither

- I tried to flash the card with the OC vbios (NVidia GTX 660m VBIOS -Overclocking Edition [DELL]; Source: T|I Dowonloads) and an original DELL vbios (Source: T|I Thread about M18x)but i get two warnings saying:

WARNING: Firmware image PCI Subsystem ID (1028.0551)

does not match adapter PCI Subsystem ID (1028.02A2).

WARNING: Firmware image Board ID (E00B) does not match adapter Board ID (E001).

After confirmation of the PCI Subsystem override with 'y' the nvflash terminates with the message "ERROR: Board ID mismatch" (see output)

C:\Users\wahnfred\Downloads\nvflash_windows_5.118>nvflash -6 "Dell GTX660M 80.07.39.00.0F VBIOS.ROM"

NVIDIA Firmware Update Utility (Version 5.118)

Checking for matches between display adapter(s) and image(s)...

  does not match adapter PCI Subsystem ID (1028.02A2).
WARNING: Firmware image Board ID (E00B) does not match adapter Board ID (E001).

Please press 'y' to confirm override of PCI Subsystem ID's:  y
Overriding PCI subsystem ID mismatch

ERROR: Board ID mismatch

The first warning is not unusual... but the second seems to mean, that I am trying to flash a non supported board, right?

So, do you have any idea, how I could get my Laptop display _and_ the display port up and running?

Kind Regards WAHNfred
