 Booting from a network device
 -----------------------------
 
-Beside the normal guest firmware (which is loaded from the file ``s390-ccw.img``
-in the data directory of QEMU, or via the ``-bios`` option), QEMU ships with
-a small TFTP network bootloader firmware for virtio-net-ccw devices, too. This
-firmware is loaded from a file called ``s390-netboot.img`` in the QEMU data
-directory. In case you want to load it from a different filename instead,
-you can specify it via the ``-global s390-ipl.netboot_fw=filename``
-command line option.

-The ``bootindex`` property is especially important for booting via the network.
-If you don't specify the ``bootindex`` property here, the network bootloader
-firmware code won't get loaded into the guest memory so that the network boot
-will fail. For a successful network boot, try something like this::
