AT89C51ED2: Selecting external vs internal flash

I would like to set a (fuse?) bit to select the external Flash/PEROM as program memory instead of default Flash internal to the AT89C51. Is the BLJB bit the one I want to set? How do I set it?

Try putting a zero in front of your F800h. That may eliminate the error.
