Sorry, you lost me. Presumably your system would not be an IBM system.
Nothing prevents you from adding a more specific DMI entry (or more
than one). Many DMI matches are for the system vendor, the board vendor,
the product name, or even the BIOS vendor, date, and/or version. Every
value in enum dmi_field can be matched.
