+      The <command>insmod</command> commands load the
+      <application>GRUB</application> modules named
+      <filename>part_gpt</filename> and <filename>ext2</filename>.
+      Despite the naming, <filename>ext2</filename> actually supports
+      <systemitem class='filesystem'>ext2</systemitem>,
+      <systemitem class='filesystem'>ext3</systemitem>, and
+      <systemitem class='filesystem'>ext4</systemitem> filesystems.
+      The <command>grub-install</command> command has embedded some modules
+      into the main <application>GRUB</application> image (installed into
+      the MBR or the GRUB BIOS partition) to access the other modules
+      (in <filename class='directory'>/boot/grub/i386-pc</filename>) without
+      a chicken-or-egg issue, so with a typical configuration these two
+      modules are already embedded and those two <command>insmod</command>
+      commands will do nothing.  But they do no harm anyway, and they may
+      be needed with some rare configurations.
