This is a 2-Kbit EEPROM with 16-byte page size. The latter half of the EEPROM is read-only, and the last 48 bits contain a globally unique MAC address. That is to say this is not an ordinary EEPROM. The compatible for this type of EEPROM was introduced later that the board. Switch over to the correct compatible now that it is available.
