Title:
  Unable to install OS/2 Warp v3 past disk 2

Status in QEMU:
  Expired

Bug description:
  To whom it may concern,

  As you may (or may not) be aware, QEMU is currently unable to readily
  install OS/2 Warp v3 (OS2W3) when asked for Installation Diskette 2
  
(http://www.claunia.com/qemu/objectManager.php?sClass=version&iId=132&iTestingId=138).

  QEMU 0.8.2 is the last known (to me) release to successfully install
  OS2W3. QEMU version 1.0 and the latest development version (as of
  2012-01-05) have been verified not to work.

  A 'git bisect' reveals the issue was introduced during a migration to
  new removable media handling prior to the QEMU 0.9.0 release:

        There are only 'skip'ped commits left to test.
        The first bad commit could be any of:
        66c6ef7678939f2119eb649074babf5d5b2666f6
        ea185bbda732dae6b6a5a44699f90c83e21f1494
        19cb37389f4641d48803f0c5d72708749cbcf318
        We cannot bisect more!

  For testing, the 'qcow' hard drive format was chosen due to QEMU 0.8.2
  not having 'qcow2':

          $ qemu -M isapc -m 8 -localtime -soundhw sb16 -hda os2.qcow
  -fda install.img -boot a

  Of note, the ISA-only PC (isapc) was needed for QEMU 0.8.2 to 0.9.0.
  Otherwise QEMU hangs on start-up. Later versions of QEMU, segmentation
  fault when attempting to use '-M isapc' though boot correctly when
  using the default PC machine.

  
  The currently preferred method to install OS2W3 is to use another application 
(such as VirtualBox or VMWare), using a QEMU compatible disk image format. Once 
installed, QEMU can then run OS2W3; which it does phenomenally well.

  However, I've identified a way to install OS2W3 exclusively with QEMU,
  which may also shed additional light on the issue.

  1. Using a relatively new QEMU (I'm on 0.11.1), install OS2W3 as you normally 
would on to a 'qcow2' hard drive.
  2. When Installation Diskette 2 is reached, save a VM snapshot.
  3. Quit QEMU and re-run, loading the VM state *with* the Installation 
Diskette 2 image in the floppy drive.
        $ qemu -m 8 -localtime -soundhw sb16 -hda os2.qcow2 -fda disk2.img 
-loadvm install 
  The installation process will then continue as normal.

  This same method can be used once OS2W3 continues installing from it's
  GUI. Installation Diskette 7 experiences the same issue of not being
  recognised when inserted.

  Of note, as an unrelated issue, I was unable to save VM snapshots in
  QEMU 1.0 or later.

  
  Thank you for a fantastic emulator.

  
  cheers,
  multitude
