I'd like to contribute but I don't know where to start.
Sounds interesting, but this needs some thought on how to design it. I suppose what you want is change the 'default' variable. Perhaps increase it by 1? But then, where do you do this? grub_machine_init is too early as 'default' hasn't been set yet. Maybe we could have a global 'int default_offset' variable that is initialized in grub_machine_init and later on used by normal.mod? -- Robert Millan The DRM opt-in fallacy: "Your data belongs to us.
