I am unable to use flashrom utility in my system. I am using EP80579 processor by Intel ans having one flashchip SST25VF061B which is connected to the processor by SPI interface.

You are using a very old flashrom version. Please use at least 0.9.1 (this will give better error messages) or latest code from svn (this might will tell you exactly what's wrong).

This message means that probing for most chips is not possible because the BIOS has forbidden the classic probe command.

Interesting. I wonder whether these messages appear even with latest flashrom from svn.

please tell me what should I change to work this utility.
Try very latest flashrom from svn. I think it will not find your chip, but "flashrom -V" will tell us if there is a chance to get it working for you.
