+Here are the 5 sections of node['dmi'] that are returned on my Ubuntu workstation, and what I believe are the Win32 equivalents.
+
+chassis: https://docs.microsoft.com/en-us/windows/win32/cimwin32prov/win32-systemenclosure
+processor: https://docs.microsoft.com/en-us/windows/win32/cimwin32prov/win32-processor
+bios: https://docs.microsoft.com/en-us/windows/win32/cimwin32prov/win32-bios
+system: https://docs.microsoft.com/en-us/windows/win32/cimwin32prov/win32-computersystemproduct
+base_board: https://docs.microsoft.com/en-us/windows/win32/cimwin32prov/win32-baseboard
+
+I think these are the equivalents.
+
+Note the first one is what is in the system_enclosure plugin today. We can copy that pattern into the dmi plugin and use it to pull all of the sections. The system_enclosure plugin should then be set for future deprecation.
