+Description:
+ The firmware provides DMI structures as a packed list of
+ data referenced by a SMBIOS table entry point. The SMBIOS
+ entry point contains general information, like SMBIOS
+ version, DMI table size, etc. The structure, content and
+ size of SMBIOS entry point is dependent on SMBIOS version.
+ The format of SMBIOS entry point and DMI structures
+ can be read in SMBIOS specification.
+
+ The dmi/tables provides raw SMBIOS entry point and DMI tables
+ through sysfs as an alternative to utilities reading them
+ from /dev/mem. The raw SMBIOS entry point and DMI table are
+ presented as binary attributes and are accessible via:
+
+ /sys/firmware/dmi/tables/smbios_entry_point
+ /sys/firmware/dmi/tables/DMI
+
+ The complete DMI information can be obtained using these two
+ tables.
