If you just run `qemu-system-i686` (no other args) you'll see the VM briefly try to boot from a floppy drive; if you run `qemu-system-i686 -global isa-fdc.driveA=` (with an earlier version of qemu, obviously) you'll see it does not do so. + +I can't see a way to do this with `-device floppy`.

If you run `qemu-system-i686 -device floppy,unit=0,drive=`, it still tries to boot from a floppy drive. + +I see there's a -nodefaults option that disables *all* default devices, but I don't think that's what we want here either. We might want the other default devices, we just don't want the floppy drive. \ No newline at end of file |
