+Vendor Differences
+~~~~~~~~~~~~~~~~~~
+
+While the Intelligent Platform Management Interface (IPMI) interface is based
+upon a defined standard, the Ironic community is aware of at least one vendor
+which utilizes a non-standard boot device selector. In essence, this could be
+something as simple as different interpretation of the standard.
+
+As of October 2020, the known difference is with Supermicro hardware where
+a selector of ``0x24``, signifying a *REMOTE* boot device in the standard,
+must be used when a boot operation from the local disk subsystem is requested
+**in UEFI mode**. This is contrary to BIOS mode where the same BMC's expect
+the selector to be a value of ``0x08``.
+
+Because the BMC does not respond with any sort of error, nor do we want to
+risk BMC connectivity issues by explicitly querying all BMCs what vendor it may
+be before every operation, the vendor can automatically be recorded in the
+``properties`` field ``vendor``. When this is set to a value of
+``supermicro``, Ironic will navigate the UEFI behavior difference enabling
+the UEFI to be requested with boot to disk.
+
+Example::
+
+    baremetal node set <UUID or name> \
+        --properties vendor="supermicro"
+
+Luckily, Ironic will attempt to perform this detection in power
+synchronization process, and record this value if not already set.
+
+While similar issues may exist when setting the boot mode and target
+boot device in other vendors' BMCs, we are not aware of them at present.
+Should you encounter such an issue, please feel free to report this via
+`Storyboard <https://storyboard.openstack.org>`_, and be sure to include
+the ``chassis bootparam get 5`` output value along with the ``mc info``
+output from your BMC.
+
+Example::
+
+    ipmitool -I lanplus -H <BMC ADDRESS> -U <Username> -P <Password> \
+        mc info
+    ipmitool -I lanplus -H <BMC ADDRESS> -U <Username> -P <Password> \
+        chassis bootparam get 5

+fixes:
+  - |
+    Fixes issues when ``UEFI`` boot mode has been requested with persistent
+    boot to ``DISK`` where some versions of ``ipmitool`` do not properly
+    handle multiple options being set at the same time. While some of this
+    logic was addressed in upstream `ipmitool <https://github.com/ipmitool/ipmitool/issues/163>`_
+    development, new versions are not released and vendors maintain downstream
+    forks of the ipmitool utility. When considering vendor specific `selector
+    differences <https://storyboard.openstack.org/#!/story/2008241>`_ along
+    with the current stance of new versions from the upstream ``ipmitool``
+    community, it only made sense to handle this logic with-in Ironic.
+    In part this was because if already set the selector value would not be
+    updated. Now ironic always transmits the selector value for ``UEFI``.
+  - Fixes handling of Supermicro ``UEFI`` supporting BMCs with the ``ipmi``
+    hardware type such that an appropriate boot device selector value is sent
+    to the remote BMC to indicate boot from local storage. This is available
+    for both persistent and one-time boot applications. For more information,
+    please consult `story 2008241 <https://storyboard.openstack.org/#!/story/2008241>`_.
+  - Fixes handling of the ``ipmi`` hardware type where ``UEFI`` boot mode and
+    "one-time" boot to PXE has been requested. As Ironic now specifically
+    transmits the raw commands, this setting should be properly appied where
+    previously PXE boot operations may have previously occured in
+    ``Legacy BIOS`` mode.
+other:
+  - Adds a ``detect_vendor`` management interface method to the ``ipmi``
+    hardware type. This method is being promoted as a higher level interface
+    as the fundimental need to be able to have logic aware of the hardware
+    vendor is necessary with vendor agnostic drivers where slight differences
+    require slightly different behavior.
+upgrade:
+  - An automated detection of a IPMI BMC hardware vendor has been added to
+    appropriately handle IPMI BMC variations. Ironic will now query this and
+    save this value if not already set in order to avoid querying for
+    every single operation. Operators upgrading should expect an elongated
+    first power state synchronization if for nodes with the ``ipmi``
+    hardware type.
