I replaced my logic board but I am missing my settings like serial numbers. How do I restore these?

You can't. Only Apple has the proper equipment and software to burn the new serial number to ROM. Why did you have to change out a logic board on a new iMac? Wasn't it under warranty? And if Apple replaced the board, take the machine back to them and have them set the new serial number for you.

I don't think that you understand. The serial number is "burned" so to speak onto the logic board. It is not a "setting".
