   Recent floppy boot regression in qemu-system-i386

Status in QEMU:
  Fix Released

Bug description:
  In recent versions of qemu-system-i386, booting from an
  emulated floppy no longer works.

  Using bisection, I have determined that the problem appeared
  with the following commit:

    commit 582299336879504353e60c7937fbc70fea93f3da
    Author: Julien Grall <address@hidden>

        hw/dma.c: Replace register_ioport_*

        Replace all register_ioport_*() with the new Memory API functions.
        This permits to use the new Memory stuff like listeners.

  One way to reproduce the problem is using the FreeDOS floppy image
  listed on http://wiki.qemu.org/Testing, by running

    wget http://odin.fdos.org/odin2005/odin1440.img
    qemu-system-i386 -fda odin1440.img

  This successfully boots FreeDOS in qemu version
  258711c6448c44b60b0fecef1d3b09c71e23e304, but not
  in version 582299336879504353e60c7937fbc70fea93f3da
  or newer.
