actual bios settings

[Bart Swinnen]

Hi

Does flashrom normally also reads actual BIOS setting of a board?
I'm trying flashrom on IEI Wafer-LX-800
It finds PMC Pm49FL004 device and I can read it.
It gives me a 512k bin file. If I write this file to another board of 
its kind, I still have the actual settings of that board and not the one 
stored in the board where I had the bin from.
Am I missing something?

Kind regards

some settings are maintained in CMOS, and flashrom can not/should not
change them as part of flashing.

Is there a way to read CMOS, and write CMOS with linux?
