  older OS's do not detect CD change

Status in QEMU:

Bug description:
  There are at least two older operating systems, being FreeBSD 2.2 and
  FreeDOS 1.2, that misbehave when the change command is used on the IDE
  CD drive, and work fine on a real machine.  In both cases, changing
  the CD causes the guest to either refuse to read the disc or appear to
  read bad data, and in both cases the guest read the disc without issue
  after a system_reset.

  A HD image that demonstrates this behavior can be produced if
  necessary, however the FreeDOS 1.2 CD can be booted directly and used
  to test:


  (choose install then abort and you get a prompt in which you can type
  "dir D:", say)

  note, running eject before the change command does nothing to help.
