I just uploaded a new version of the TSMBIOS library with support for Linux via Delphi 10.2 Tokyo. You can found a full description of the project in the Github site.
Check these screenshots of the demo applications running under ubuntu 16.04 LTS
Now just a small note, the TSMBIOS library access to the SMBIOS data reading the /dev/mem device file (which provides direct access to system physical memory). So the applications which uses this library require being executed by an user with access to such file, typically a superuser.
