Just to make sure I understand this correctly... My 1st pof (combined sof and elf) will have the default Altera bootloader in it. This will search for the elf, starting at address 0, and load it into RAM. My 2nd pof, sitting at address 0x200000, is started when I send a reconfig command via NIOS code. I assume this has it's own copy of the default Altera bootloader in it, so it also searches from address 0 for the elf. So I am assuming what I need is the default bootloader in the 1st pof (as it is now) and a modified bootloader in the 2nd pof which starts looking for the elf at address 0x200000.

Does this sound about right?
