dmidecode not working because /dev/mem is missing

[firewave]

/usr/sbin/dmidecode

dmidecode 2.12

/dev/mem: No such file or directory

I think the data parsed and shown by dmidecode is available in Windows itself via WMI and there is also a gnuwin32 version of dmidecode that works natively, so the data it requires should be available.

My Windows version is Windows 10 for Enterprise Version 1607 Build 14393.222
