# Default drive semantics:
#
# By default you get a single empty floppy drive. You can override it with
# -drive and using the same index, but if you use -drive to add a floppy to a
# different index, you get both of them. However, as soon as you use any
# '-device floppy', even to a different slot, the default drive is disabled.
