Le procédé consiste : à initialiser la valeur d'un compteur d'erreurs (S101) ; chaque fois que l'exécution de n'importe quel niveau de programme d'amorçage échoue pendant le processus d'amorçage d'un serveur ARM, à déterminer si la valeur du compteur d'erreurs atteint une valeur seuil prédéfinie (S102) ; tant que la valeur n'atteint pas la valeur seuil prédéfinie, à modifier la valeur du compteur d'erreurs selon une règle prédéfinie et à redémarrer le niveau de programme d'amorçage (S103) ; et dès que la valeur atteint la valeur seuil prédéfinie, à restaurer des informations de configuration d'un processeur ARM à un réglage par défaut et à redémarrer le niveau de programme d'amorçage après restauration des informations de configuration du processeur ARM au réglage par défaut (S104). Grâce au procédé, un réglage d'erreur d'un serveur ARM peut être automatiquement restauré, ce qui permet d'assurer un amorçage normal du serveur. On divulgue en outre un appareil de restauration d'amorçage destiné à un serveur ARM et un dispositif et un support de stockage lisible par ordinateur, présentant tous lesdits effets techniques.
