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. |
