I'm bringing this post back to life, since I don't own the only supported EEPROM, 24lc256.
Like I said in the first post, I found a library called EEPROM24. the libries are well documented,(http://rweather.github.com/arduinolibs/classEEPROM24.html
But since the library don't come with some example code, I finds it really hard understanding how to write code with it.
I've included all the library files posted at the developers github in a zip-file, if some are willing to help. If I can get this library working, I can use the whole 24lcXX EEPROM series easily
