Now, part of my problem is that when I power on my laptop (last operation was a suspend-to-disk in Linux), I don't have to use any resume option or menu entry in grub. When the machine boots, it directly does a resume of the suspended Linux. How to get the grub menu so that I can jump in XP (then decide to resume the suspended Linux later)? Regards, -- wwp
