Method of setting addresses of memories

摘要

A method of installing add-on memories capable of setting continuous addresses over the add-on memories and already existing memories comprises the steps of selecting a desired memory mounting portion among a plurality of memory mounting portions, judging the presence or absence of each memory in the selected memory mounting portion, and setting top and end addresses in the memory mounting portion so that the address of each memory mounted on the selected memory mounting portion continues to addresses of the memories mounted on other memory mounting portions when it is judged that each memory is mounted on the selected memory mounting portion.
