Hi Tobias,
I used UEFItool to extract the Nvidia option ROM, that wiki page under
"UEFI method":
https://www.coreboot.org/VGA_support
On the T430 I found two blobs, one of about 60k in size and one that's
about double the size, but I wasn't able to properly test yet which one is
needed.
Hello Michał,
which size got your option ROM for the Nvidia card?
Regards,
Tobias.

Hey Christoph,
I had also a first tryout with the UEFItool and had one ROM extracted.
But afterwards did this with PhoenixTool and got two ROMs with the same
size. Thanks for the hint afterwards, because one ROM seems not working
after all. I'll have a look in the dumped list from PhoenixTool.

Hello everybody!
I have problems with getting coreboot running on a Lenovo ThinkPad
T430.
Better to say: Running with the integrated second graphics adapter NVS
5400M. The Intel HD 4000 is working fine and from the wiki I know that
NVidia Optimus is not supported for now. So what to do exactly
