| 4 | Description: | |
| 5 | The firmware provides DMI structures as a packed list of | |
| 6 | data referenced by a SMBIOS table entry point. The SMBIOS | |
| 7 | entry point contains general information, like SMBIOS | |
| 8 | version, DMI table size, etc. The structure, content and | |
| 9 | size of SMBIOS entry point is dependent on SMBIOS version. | |
| 10 | The format of SMBIOS entry point and DMI structures | |
| 11 | can be read in SMBIOS specification. | |
| 12 | ||
| 13 | The dmi/tables provides raw SMBIOS entry point and DMI tables | |
| 14 | through sysfs as an alternative to utilities reading them | |
| 15 | from /dev/mem. The raw SMBIOS entry point and DMI table are | |
| 16 | presented as binary attributes and are accessible via: | |
| 17 | ||
| 18 | /sys/firmware/dmi/tables/smbios_entry_point | |
| 19 | /sys/firmware/dmi/tables/DMI | |
| 20 | ||
| 21 | The complete DMI information can be obtained using these two | |
| 22 | tables. |
