When reading from BIOS I got 1024kB file.

Maybe I will send you both files so you can compare them ?

Hello Marek,

thanks for your report!
Please do not send html(-only) message to mailing lists. The board was
locked down by intel so that only bios code can access the flash chip.
There may or may not be a way to enable access to the host software
(like flashrom), but this would need to be reverse engineered.
Regarding the image size: flashrom  just writes the file it gets as
input to the device. It must be prepared so that it fits, else it wont
continue as you have seen. Maybe your image contains actually 2
firmwares or is the wrong one...

I have added your board to our list of (un)supported board for now and
will commit that later.
Kind regards/Mit freundlichen Grüßen, Stefan Tauner
