[coreboot] Need Help

[Reihane kamaly]

Hello,
My name is Seiede Reyhane Kamali and I am a Phd student. For my project, I need to run different configurations of coreboot. I read all the tutorials and tried them but I still can't figure out how to run different configurations. I will appreciate it if you can help me with this issue.

Thanks in advance,Reyhane
