+<title>Additional steps to enable the Secure Boot firmware option</title>
+<para>
+On some systems, the firmware option to switch the Secure Boot state
+is not always active and cannot be selected.  The following additional
+measures are worth a try.

+    <para>
+      Set a non-empty supervisor password in the firmware.  This may
+      enable the Secure Boot option.  After toggling this option, you
+      can remove the supervsior password again.  Depending on the
+      firmware, you may have to set the password to an empty string to
+      disable it.

+      Firmware may only allow changing the Secure Boot settings after
+      a physical presence check.  The following keyboard options may
+      not pass the physical presence check:

+	  a USB keyboard connected to a laptop

+      The Secure Boot option might be protected, but access to the
+      Secure Boot key store is not.  Removing all keys in the key
+      store can disable Secure Boot even if the separate option for
+      this purpose cannot be switched off.
