+# Set the screen's video resolution. Pass this option two values,
+# corresponding to the X and Y resolutions. Note that not all resolutions
+# are supported. On UEFI systems, passing an incorrect value results in a
+# message being shown on the screen to that effect, along with a list of
+# supported modes. On EFI 1.x systems (e.g., Macintoshes), setting an
+# incorrect mode silently fails. On both types of systems, setting an
+# incorrect resolution results in the default resolution being used.
+# A resolution of 1024x768 usually works, but higher values often don't.
+# Default is "0 0" (use the system default resolution, usually 800x600).
