j'ai appliqué ce qui est recommandé dans le wiki d'optimisation des 
périphériques ide

mis amd74xx dans le /etc/modules an premier

mais au reboot, ça freeze au niveau de Loading modules

Je dois passer par le LiveCD pour commenter mon rajout pour rebooter.

Un conseil pour pouvoir activer le dma sur mon lecteur ?

Merci d'avance,

DoK
