Print mainboard vendor and model for this hardware, if available. This option requires that the dmidecode(8) utility be installed, and must be run as root.
Print the status of EDAC drivers (loaded or unloaded).
Register motherboard DIMM labels into EDAC driver sysfs files. This option uses the detected mainboard manufacturer and model number in combination with a "labels database" found in any of the files under /etc/edac/labels.d/* or in the labels.db file at /etc/edac/labels.db. An entry for the current hardware must exist in the labels database for this option to do anything.
Display the configured labels for the current hardware, as well as the current labels registered with EDAC.
Specify an alternate location for the labels database.
