Hi! I can't read the name of the flash chip on the motherboard. Try to read it later with magnifying glass.
Hi Александр,
that board contains two flash chips actually. Only the second one (1 MB) is used for the x86 firmware. The other one (8 MB) is for the Management Engine (ME). It is not possible to access the second chip alone so flashrom expects the input file to be 8 MB + 1 MB = 9 MB. You could try swapping the last 1 MB of the image you read with the h55ms2.f3 file contents. If you know what you are doing, this should be safe.
You can find out what the first chip is by using "-p internal:ich_spi_mode=swseq".
