Something else I don't understand.
In win10, the card works fine in optimus mode.
I ran furmark, everything works correctly.

But if the peg mode is set in bios, I get 8 beeps.
Why is that?

Thanks @Klem! 
gm204mod.rom still works and does not hang.
I will be testing more.
Another question: driver 471.41 is not installed ("This graphics driver did not find a compatible graphics hardware"). 
The last driver we managed to install is 399.24. Is this a feature of vbios-mod?
Is it possible to install 471.41 without modifying the inf file?

Hi!

You can post here your stock vbios from your 980M, I can take a look.

Try to flash attached vbios.

Hi guys! 

@Klem , can you upload the file gm204mod.rar that you gave for Skyl3r again? 

@Skyl3r, maybe you still have this file?  I have the same laptop (m17xr4), I am also trying to upgrade to 980m (dell, 8gb) and I have a very similar problem. 

Thanks
