Hi,

I doubt that this is caused by int 13, as grub2 doesn't change it.
Besides, the boot sector is read properly in grub2, so int 13 should
be working.

I have thought of another possible reason for this. In grub2, %dh is
0, perhaps it should be set to the partition number. Please test if
the new patch works.
