eeprom address for node id

[Mickey]

Hi
I want to develop a node that need to save some data to local node eeprom. but I wouldn't want to erase the node id and other params that the mysensors library saving.
how much room is available for my node ( arduino pro mini 328 ) and from where can I write to eeprom without erasing anything?

If you use the MySensors provided functions (saveState) you can store 256 bytes without overwritnig anything.
