|  | 332 | The TCO (Total Cost of Ownership) timer is a watchdog timer | 
|  | 333 | that will reboot the machine after its second expiration. The | 
|  | 334 | expiration time can be configured with the "heartbeat" parameter. | 
|  | 335 |  | 
|  | 336 | On some motherboards the driver may fail to reset the chipset's | 
|  | 337 | NO_REBOOT flag which prevents the watchdog from rebooting the | 
|  | 338 | machine. If this is the case you will get a kernel message like | 
|  | 339 | "failed to reset NO_REBOOT flag, reboot disabled by hardware". |
