Not all Super I/O chipsets provide a Floppy Disk Controller. Without this change, using a Super I/O with no FDC would abort QEMU with: Initialization of device isa-fdc failed: ISA controller does not support DMA Signed-off-by: Philippe Mathieu-Daudé <philmd@redhat.com> --- hw/isa/isa-superio.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-)
