I wrote the way i had build coreboot. Tianocore is not the default
payload. The default payload recently is (i checked now) SeaBIOS
1.11.2
.
I have not touched anything at the payload. I just leave everything
default and would like to be able to see the output of coreboot so
that
i can choose for example to boot from a usb-pendrive.
What should i do now to get the <everything at default coreboot> to
show
output on the screen?
