4 QEMU can tell QEMU-aware guest firmware (like the x86 PC BIOS)
6 A simple way to set this order is to use the ``-boot order=`` option,
19 not support ``-boot order=``; on those machines you must always
22 There is no way to set a ``bootindex`` property if you are using
23 a short-form option like ``-hda`` or ``-cdrom``, so to use
25 into long-form ``-drive`` and ``-device`` option pairs.
