-Access to physical addresses is provided by a kernel-mode driver, virt2phys.
-It is mandatory at least for using hardware PMDs, but may also be required
-for mempools.
-
-Refer to documentation in ``dpdk-kmods`` repository for details on system
-setup, driver build and installation. This driver is not signed, so signature
-checking must be disabled to load it.
+Certain kernel-mode drivers are required to run DPDK applications.
+Refer to `Windows documentation <https://git.dpdk.org/dpdk-kmods/tree/windows>`_
+in ``dpdk-kmods`` repository for common instructions on system setup,
+driver build and installation.
+The drivers are not signed, so signature enforcement has to be disabled.
 
 .. warning::
 
     Disabling driver signature enforcement weakens OS security.
     It is discouraged in production environments.
 
-Compiled package consists of ``virt2phys.inf``, ``virt2phys.cat``,
-and ``virt2phys.sys``. It can be installed as follows
-from Elevated Command Prompt:
-
-.. code-block:: console

-    pnputil /add-driver Z:\path\to\virt2phys.inf /install

-1. From Device Manager, Action menu, select "Add legacy hardware".
-2. It will launch the "Add Hardware Wizard". Click "Next".
-3. Select second option "Install the hardware that I manually select

+NetUIO kernel-mode driver provides access to the device hardware resources.
+It is mandatory for all hardware PMDs, except for mlx5 PMD.

+Refer to `NetUIO documentation <https://git.dpdk.org/dpdk-kmods/tree/windows/netuio/README.rst>`_
