[coreboot] 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
