[Bernie E. <be...@gm...>]

This is probably more useful than just 'intel NUC i7'::

System-manufacturer :  Intel(R) Client Systems
System-product-name :  NUC10i7FNH
Bios-release-date :  04/09/2021
Bios-version :  FNCML357.0052.2021.0409.1144

Let me know if you need more detailed info.  regards,bernardo
