No, that's all you need to do! The KERNAL will automatically recognize 
more moemory - expect ~ two times slower startup with unmodified KERNAL 
because it tests each memory cell.

You can install BASIC 256 ROMs after memory expansion, but this is not 
strictly necessary, BASIC 128 will work just fine but will not use the 
extended memory of course.
