+          Hardware driver for the TCO timer built into the nVidia Hub family
+          (such as the MCP51).  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".
+
+          To compile this driver as a module, choose M here: the
+          module will be called nv_tco.
