Help text

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.
