I have to admit that I still do not quite understand your concerns here.
Real hardware either has to have a patched TOS, or an AUTO folder program
for doing Maddalt() and installing a _FRB cookie. So either way, there
should be a _FRB cookie, otherwise the floppy disk is unusable, isn't it?
Or is there a hardware extension for the Falcon that really works without
the _FRB cookie? If so, how did they manage to get the floppy disk working
in that case?
