It's referring to the configuration tool version 1. Version 2 of the 
configuration tool doesn't yet have support for the memory layout. Until 
then you have to edit the mlt*.ldi and mlt*.h files by hand.

Probably ;-). Have a look at both the .ldi and .h files for the addresses 
*throughout* the files. I guess you may have only changed the "MEMORY" 
bits at the top of the .ldi file.
