I found a VGA Biosfile and I am able to compile Coreboot and flash it via a RaspberyPI and an adapter clamp.
Linux and X11 are running fine on this board. I even could get Windows 7 to boot 2 times (out of dozen attempts). So the Hardware is in perfect condition.
But most of the time, while booting Windows the board just stalls after the Windows7 boot animation, or it is showing the Windows loading progress bar animation for hours(!).
So I decided to go back to normal Bios to get this board in a more usable state.
Is this possible without having a backup of the original Bios?
Is there maybe a Bios dump available which I could download and flash onto the chip?
The simplest option by a long shot (considering the relatively large popularity of coreboot for your PC) is indeed flashing someone else's backup (editing the ethernet MAC address back to yours if you care) -
or, since coreboot only edits the BIOS part of the full rom AFAIK and you have a known working hardware flasher, it could be possible to manually paste the .FL1 bios image at the right address of the full image - if the FL1 isn't a compressed or encrypted format, at least!

I agree with you there, but I am unable to find an SPI dump.
I could find an X230 SPI dump, but this does not help.
This seems to be not possible because I'm unable to extract the bios from the FL1 file. The FL1 seems to be no simple UEFI container.Ryccardo wrote: ↑Mon Oct 09, 2017 12:30 pmor, since coreboot only edits the BIOS part of the full rom AFAIK and you have a known working hardware flasher, it could be possible to manually paste the .FL1 bios image at the right address of the full image - if the FL1 isn't a compressed or encrypted format, at least!
Could this be?
Only the EC is, but that's not enough.
Also, your title says you're looking for X220, so why bother with a (totally different) X230 dump?
If you need extensive changes in your X220 BIOS, look at McDonnell's stuff: http://x220.mcdonnelltech.com/resources/

Since this device can't boot Windows, I can't use the standard Bios update utility.
I'm unable to extract a Bios dump from official or unoffical X220 Bios update (*.FL1).
But, I could flash this Bios via RaspberryPi and flashrom, for this I would need a Bios dump.
I could not yet find an X220 Bios dump on the net.
Could someone please provide me a X220 bios dump?
In case you haven't solved your problem yet, try these instructions for getting the BIOS part of the FL1 file. You should apply them to a BIOS version which came with the same EC firmware version, preferably to the last version you had on the X220 before flashing Coreboot.
