I'm kind of wanting to do the same thing in an A2000 (have a Gotek but also have the ability to boot from the real floppy too).
With an A2000, which has provision for two floppy drives internally, would this be any easier?
I'm just thinking, maybe I should just put the Gotek as DF1: (drive 2) and use the early startup menu in KS3.1 to boot from DF1:
That would be just as good as making some hardware switch, no?
