# The timeout period of the BIOS Watchdog must be long enough to ensure that Windows has enough time to boot up and starts the Watchdog service
== Watchdog Usage in Windows ==
1.1. Command Prompt: <br>
* Open the Command Prompt (CMD) in Administrator Mode
* Click on the Uninstall Watchdog
* Restart the computer
 
== Watchdog Usage in Linux ==
* '''NOTE!''' Not supported in mainline Linux kernel yet. '''[http://fit-pc.com/wiki/index.php/Fitlet:_Linux:_Kernel Linux Kernel for Fitlet]''' should be installed to make this feature work
* The AMD FCH (Fusion Controller Hub) supports a user configurable watchdog
* Once the watchdog is enabled the system restarts once the timeout period elapses, in order to prevent it the user needs to either feed the watchdog or to disable it
$ sudo apt-get install watchdog
* Uncomment watchdog-device line in /etc/watchdog.conf
watchdog-device = /dev/watchdog
* Set responsible kernel module to sp5100_tco in /etc/default/watchdog
watchdog_module="sp5100_tco"
* By default the timeout value is 60 sec and the watchdog deamon feeds the watchdog every 10 sec
* As example you can simulate kernel panic (as root user):
$ echo c > /proc/sysrq-trigger
* As a result, the watchdog is not fed and the system will reboot after 60 sec
