You need to add the VGA Option ROM (VGA BIOS -> Add VGA BIOS image).
I've extracted it from the UEFI, but you also could use these:

http://www.coreboot.org/index.php?title=ASRock_E350M1&oldid=11114

at the end of the page or you also may be able to use the default AMD
fam14 (Persimmon) vbios. You will need to agree to the click through:

http://wwwd.amd.com/support/vbioslic.nsf/userverify?openform

http://www.coreboot.org/AMD_DB-FT1_PERSIMMON

It's a pity, that bios_extract didn't work for now.
You could use the AMI Aptio EFI MMTool with wine:

http://win-lite.de/benutzer/fernando/BIOS-Tools/AMI_Aptio_EFI_MMTool_v4.50.0...

You need to extract OntarioEFIVbios with PCI ID 1002,9802 as Option ROM.

I simply forgot to extract the vga bios. now I don't know how to fix it
without graphical output from the machine.

Question about internat flashing over existing coreboot payloads - x220

[diffusae]

Hello!

"Once you are running coreboot any subsequent flashes can be done
internally, however you will have to force flashrom"

https://www.coreboot.org/Board:lenovo/x220

Is that really possible, without any risk? Doesn't it irritating the
embedded controller? Can I ignore the flashrom warnings?

Yes. No (which EC do you mean? why would it be irritated? why is the
output of a random program automatically correct?). Yes.

Flashrom contains imprecise blanket statements.

Be careful, and always have a way to recover from a non-working image.

Thanks a lot for your answer.

I mean the EC firmware of the x220, for keyboard, power management and
battery, etc. Or is it located on a different chip? I see, it's not part
of the flash chip layout.

Yes, you are right, but the warning sounds so strange. ;-)

Good to know

An external SPI Flasher and a working image should be one way.

BTW: USB 3.0 is working, but one can't boot it via SeaBIOS.

Keyboard and power management tends to be split into two on
Thinkpads, but in any case yes, those controllers generally either
have separate flash for firmware or are ASICs without firmware.

It originates from good intentions of course, "better safe than
sorry", but I think it is a bug to display it when it actually does not
apply.

Flashrom could be improved to not display some of them when they are
known not to apply, such as in your case, but there are other cases
where flashrom can't really know if the warning is needed or not.
That's more difficult.

Yep - excellent!

Maybe send a message to the SeaBIOS mailing list about that. I don't
know if that is actually expected to work. Sorry.
