For this kind of debugging, it is better to use the grub shell rather than the
native version, because that is much faster and safer.

For example, you can assign a file to a drive like this:
grub> device (fd0) /dir/file

Then, you can read (fd0) as usual. You can even attach gdb in the same way as
you debug ordinary programs.

Yes. Take a look at the memory map in the manual and the script "size_test" in
the directory "stage2".
