http://rapidshare.com/files/82696074/flashrom_files.tar.gz.html

the file random_original.rom is the file i writed to the chip, where this file 
was created using dd and /dev/urandom.
the file random_read.rom is the file which i've read with flashrom after 
writing the random_original.rom to the chip.
