+ * 'core' (which is 'diskboot' concatenated with 'kernel' and
+ * all the modules, this is created by grub-mkimage).  This resulting

+ * of a partition.
+ *
+ * The initial 'diskboot' block acts as a loader for the actual GRUB
+ * kernel.  It contains the loading code and then a block list.
+ *
+ * The block list of 'core' starts at the end of the 'diskboot' image
+ * and works it's way backwards towards the end of the code of 'diskboot'.
+ *
+ * We patch up the images with the necessary values and write out the
