hi:) i am debuging my kernel . Before the idt_setup of protect-mode , Is it normal that one page_fault exception occures? As I step into this instruction : lss stack_start,%esp , vm fire an page_fault exception, But at the intr vector check step, as the intr-table has not been setup . so it gives this : interrupt(): vector must be within IDT table limits, IDT.limit = 0x0. How to resolve this issure? thanks! _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
