Maybe I didn't include the VGA option in the make menuconfig process. How can I solve this problem?
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. Regards, Reiner --

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

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. //Peter
Thanks a lot for your answer. On 12.09.2017 01:29, Peter Stuge wrote:

Yes. No (which EC do you mean? why would it be irritated? why is the output of a random program automatically correct?). Yes.
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. ;-)
Flashrom contains imprecise blanket statements.
Good to know
Be careful, and always have a way to recover from a non-working image.
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. Regards, Reiner -- .

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

Good to know
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!
BTW: USB 3.0 is working, but one can't boot it via SeaBIOS.
Maybe send a message to the SeaBIOS mailing list about that. I don't know if that is actually expected to work. Sorry. //Peter
