Well both chips failed verify. Read and Erase seems to work fine, yet verify
seems to fail at the same place for both chips 0x2f. Doing less on written
binary it seems that there are areas that were left zeroed, and unwritten.
For both chips pattern seems to be the same.

Do I blame eeprom and return them or problem is elsewhere?

./flashrom -r ATC-6220.Award.1-1-03-WB.orig.bin
Calibrating delay loop... ok
No LinuxBIOS table found.
Enabling flash write on PIIX4/PIIX4E/PIIX4M...OK
W29C020C found at physical address: 0xfffc0000
Flash part is W29C020C (256 KB)
Reading Flash...done
