+ ---help---
+ 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.
