dual gfx card

[Karoly Laszlo Konya]

Hi all,

I want to start one AMD Parmer board with an external GFX card and integrated GPU.

The original AMI BIOS with 
 - Primary Video Device [NB PCIe slot Video] and 
 - Integrated Graphics [Auto] 
options works fine, but I can't set up the coreboot for the same configuration.
My operation system is linux and I have prepared an ELF executable payload too.
I tried to start my coreboot with SeaBios or with the kernel payload, without success.

Anyone, who have experience in this field, could help me?

Thanks in advance
Karoly

Dear Karoly,

welcome to coreboot!

(Please note that the official spelling is SeaBIOS.)

What is the actual error?

Unfortunately not a lot. What coreboot hash/revision did you build your
image from? Please paste the verbose log of coreboot and Linux, so we
can actually see what the error is.

On the AMD Fam 14/SB800-based ASRock E350M1, I am also not able to use
an external graphics card. The free Radeon driver developers told me,
that coreboot does not disable the internal card enough [1].

Thanks,

Paul
