[flashrom] Difference of factory bios and dumped image

[Paul Menzel]

Dear Parkash,


please do just send plain text messages to mailing lists [1]. Since you
are using KMail this should  be easily configurable.

Unfortunately this question seems not be listed in the FAQ. Most of the
time some areas differ because the MAC address and other configuration
data of the downloaded images differs [2]. I hope you mean the
downloaded image by factory/vendor image.
