Abstract

La présente invention concerne un terminal doté de multiples systèmes d'exploitation (multi-OS). Le terminal prend en charge un premier système d'exploitation (OS) et un second système d'exploitation (OS). Des fichiers de système du premier OS et du second OS sont mémorisés respectivement dans une première partition et une seconde partition d'un espace de mémoire interne du terminal. Les fichiers de système du premier OS sont mémorisés dans la première partition à partir d'une adresse nulle. Également, les fichiers de système du second OS sont mémorisés dans la seconde partition à partir d'une adresse nulle. La présente invention réduit la complexité de la conception de logiciel de l'OS installé dans le terminal.
