it optional as I'm not able to confirm the eeprom format is the same on earlier cs89x0's. Certainly the my 8920M and the data sheet for 8900A use the same format. This allows my RiscStation to examine the cs's eeprom to find it's mac address, previously it was unable to do this, as the eeprom offsets were hard coded for locating the mac address.
