Connaître sa carte mère sous Linux

Parfois on a besoin de connaitre toutes les infos concernant la carte mère de son ordinateur, pour se dépanner ou pour changer des composants.
Ses informations ne sont pas toujours présentes dans le manuel.
Il existe sous Linux une commande à taper dans un terminal qui vous affichera les précieuses informations.

La commande est à taper dans un terminal en tant qu'administrateur, c'est à dire en "root"
Sous ubuntu par exemple ce sera :

sudo dmidecode

Une fois que vous aurez tapé votre mot de passe vous aurez le résultat de la commande qui se présente comme ceci (c'est assez long):

chris@chris-pc:~$ sudo dmidecode
[sudo] password for chris:
# dmidecode 2.11
