Graynomad:
use to expand flash memory of the my arduino mega 2560?
The Rugged Circuits expansion board was for RAM not flash, on an AVR there is no way to execute program from external memory AFAIK.
If your program really needs to be that big you better start looking at a different platform. It maybe that you could optimise it a lot, but at that size I'm not going to suggest that you post your code
