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

Enabling flash write on PIIX4/PIIX4E/PIIX4M...OK
