Abstract

La présente invention concerne un procédé de configuration automatique de monocarte, essentiellement pour le domaine des communications. En l'occurrence, une fois qu'on a enfiché sur le châssis la monocarte, qui est au standard PCI compact, la carte système reconnaît automatiquement la monocarte et envoie à l'espace SROM de la monocarte l'information de configuration, avec l'espace de mappage PCI compact. La monocarte accomplit automatiquement la configuration selon l'information de configuration dans l'espace SROM, puis commence à s'exécuter après le lancement. Cela fait que la monocarte peut être reconnue et configurée automatiquement.
