EEPROM clear

I have a UNO and was wondering if I use this program will it work with this board?
Or do I have set it up to see the board as an UNO
I am new at this stuff.

Are you referring to EEPROMClear?

That program will take into account the selected board (tools → board) and hence the size of the EEPROM. The below program will display the size of the eeprom; the function EEPROM.length() is used by EEPROMClear.

#include <EEPROM.h>

void setup()
{
  Serial.begin(9600);
  Serial.print("EEPROM size: ");
  Serial.println(EEPROM.length());
}
