Unfortunately, at this point I'm getting the infamous "BIOS panic at
rombios.c, line 1558" error:
  $ qemu -hda win98.img -boot d
  Serial port redirected to /dev/pts/3
  QEMU 0.5.5 monitor - type 'help' for more information
  (qemu) BIOS panic at rombios.c, line 1558


  $ ls -l
  total 124784
  -rw-rw-r--    1 jonc     jonc     2048000000 May 25 10:32 win98.img
  -rw-rw-r--    1 jonc     jonc     127647744 May 25 10:37 win98.iso

I created the img file using /dev/zero and then I copy up the win98se
disk to an iso image. I can mount the ISO image via loopback and it
works fine.
