+          This is the driver for the hardware watchdog found on the IEI
+          single board computers EPIC Nano 7240 (and likely others). This
+          watchdog simply watches your kernel to make sure it doesn't freeze,
+          and if it does, it reboots your computer after a certain amount of
+          time.
