OK, so instructions followed from fms_20.lha, installed and I can mount and unmount the floppy drives. However, I have no idea how to use these to mount .adf images to them.
I've tried using adf2disk to write adfs to ff0, but get errors like "'DOS' is not a valid word". Mounting them, such as "C:Mount foo.adf FF0:" gives the same error.
Ami I missing something? The manual is very sparse on actual usage.
