The best way to determine if the controller has the new or old boot flash is to compare the serial number on the printed circuit board with the numbers listed below:
UNC New Boot Flash (requires 529)
- UNC-410:Serial number 36218 or greater, shipped 6/16/10
- UNC-520:Serial number 36184 or greater, shipped 6/16/10
ENC New Boot Flash
- ENC-410:Serial number 263187 or greater, shipped 5/18/10
