Hi Mark and welcome!

I'm afraid there is no simple answer, that why there is no response yet.
I got an ethernet bootloader running, but you cannot just copy it, unless you use

-WIZ820IO module
-ATmega1284
-external EEPROM 24A1025

BTW it would take me hours to strip down my prog to leave only the BL part.
Here's how it works:
A little proggy on a PC loads up the .hex file to the ATmega1284 line by line.
Data of each line is stored away to the EEPROM.
Then the bootloader is started and writes data from the external EEPROM to the megas flash.
