Désactiver le mode SATA du controleur

Bonjour,

Je voudrais désactiver le mode SATA de mon controleur de disque dur afin de pouvoir installer win XP sur mon poste exécutant win vista. Voici la configuration de mon BIOS. Quelqu'un peut-il m'aider?
J'arrive à entrer dans le BIOS. Mais je n'arrive pas à modifier le mode SATA. Mon BIOS ressemble à ça:
