+Remain in the “Advanced → Boot Feature” page and select “Watch Dog Function”.
+The watch dog function serves to reboot the server if it experiences an error it cannot recover from (and so hangs) for more than 5 minutes. It works by starting a 5 minute count-down timer when the server hangs. When this timer reaches zero the system is forced to reboot.
+When I first tried this in FreeNAS it caused my system to spontaneously reboot every 5 minutes even though the system was not hanging, so I disabled it.

+==== AES-NI Encryption ====
+If you intend to encrypt the information on your storage drives then you need to enable this in the BIOS.
+This can be useful as it allows a failing HDD in a vdev to be discarded without worrying about wiping the information before disposal.
+Go to the “Advanced” page.
