+Hardware Interfaces
+^^^^^^^^^^^^^^^^^^^
+
+The ``ilo`` hardware type supports following hardware interfaces:
+
+* boot
+    ``ilo-virtual-media`` and ``ilo-pxe``. They can be enabled via the
+    ``enabled_boot_interfaces`` option:
+
+    .. code-block:: ini
+
+        [DEFAULT]
+        enabled_hardware_types = ilo
+        enabled_boot_interfaces = ilo-virtual-media,ilo-pxe
+
+    .. note::
+       ``ilo-virtual-media`` is the default ``boot`` interface for ``ilo``
+       hardware type.
+
+* inspect
+    ``ilo`` and ``inspector``. They can be enabled via the
+    ``enabled_inspect_interfaces`` option:
+
+    .. code-block:: ini
+
+        [DEFAULT]
+        enabled_hardware_types = ilo
+        enabled_inspect_interfaces = ilo,inspector
+
+    .. note::
+       ``ilo`` is the default ``inspect`` interface for ``ilo``
+       hardware type. `Ironic Inspector <https://docs.openstack.org/ironic-inspector/latest/>`_
+       needs to be configured to use ``inspector`` as the inspect interface.
+
+* management
+    ``ilo``. It can be enabled via the
+    ``enabled_management_interfaces`` option:
+
+    .. code-block:: ini
+
+        [DEFAULT]
+        enabled_hardware_types = ilo
+        enabled_management_interfaces = ilo
+
+* power
+    ``ilo``. It can be enabled via the
+    ``enabled_power_interfaces`` option:
+
+    .. code-block:: ini
+
+        [DEFAULT]
+        enabled_hardware_types = ilo
+        enabled_power_interfaces = ilo
+
+The following command can be used to enroll a ProLiant node with
+``ilo`` hardware type:
+
+    .. code-block:: console
+
+        openstack baremetal node create --os-baremetal-api-version=1.31 \
+            --driver ilo \
+            --deploy-interface direct \
+            --raid-interface agent \
+            --driver-info ilo_address=<ilo-ip-address> \
+            --driver-info ilo_username=<ilo-username> \
+            --driver-info ilo_password=<ilo-password> \
+            --driver-info ilo_deploy_iso=<glance-uuid-of-deploy-iso>
+
+Please refer to :doc:`/install/enabling-drivers` for detailed
+explanation of hardware type.
+
+To enable the same feature set as provided by all iLO classic drivers,
+apply the following configuration:
+
+    .. code-block:: ini
+
+        [DEFAULT]
+        enabled_hardware_types = ilo
+        enabled_boot_interfaces = ilo-virtual-media,ilo-pxe
+        enabled_power_interfaces = ilo
+        enabled_console_interfaces = ilo
+        enabled_raid_interfaces = agent
+        enabled_management_interfaces = ilo
+        enabled_inspect_interfaces = ilo
+
+The following commands can be used to enroll a node with the same
+feature set as one of the classic drivers, but using the ``ilo``
+hardware type:
+
+* ``iscsi_ilo``:
+
+    .. code-block:: console
+
+        openstack baremetal node create --os-baremetal-api-version=1.31 \
+            --driver ilo \
+            --deploy-interface iscsi \
+            --boot-interface ilo-virtual-media \
+            --driver-info ilo_address=<ilo-ip-address> \
+            --driver-info ilo_username=<ilo-username> \
+            --driver-info ilo_password=<ilo-password> \
+            --driver-info ilo_deploy_iso=<glance-uuid-of-deploy-iso>
+
+* ``pxe_ilo``:
+
+    .. code-block:: console
+
+        openstack baremetal node create --os-baremetal-api-version=1.31 \
+            --driver ilo \
