+	  Hub family 'from ICH0 up to ICH7) and in the Intel 6300ESB
+	  controller hub.
+
+	  The TCO (Total Cost of Ownership) timer is a watchdog timer
+	  that will reboot the machine after its second expiration. The
+	  expiration time can be configured with the "heartbeat" parameter.
+
+	  On some motherboards the driver may fail to reset the chipset's
+	  NO_REBOOT flag which prevents the watchdog from rebooting the
+	  machine. If this is the case you will get a kernel message like
+	  "failed to reset NO_REBOOT flag, reboot disabled by hardware".
