Sorry Zetro you're wrong here. It's just that the CPU command does not give errors. You can execute the whoƶe set of "cpu cache burst copyback fastrom" on any processor.
FASTROM can not work without MMU unless you have relocation tables, like zkick has. Sometimes CPU allocates memory for the rom image, though there's no MMU. Maybe your observation is based on that bug.
BTW CPU happily maps the Kickstart to Chip RAM when there is no Fast RAM but a MMU.
