Gigabyte H55M-S2 don't reflashed

[Александр Трубицын]

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".

Hello Александр,

thanks for your report!
I have added your board to our list of supported hardware and will
commit that later together with other small changes.
