Since nothing except your code talks to the EEPROM, it is all 'reserved', till you start to change it.
You can preset values in it during programming, using the #ROM directive. It is at address 0x2100, on 16 chips, and 0xF00000 on 18 chips.
The normal practice, would be to preload a 'marker' byte, that says that the area is not yet programmed. Perhaps something like 0X55, which you change to 0xAA once you have saved the required calibration.
