10 character special file /dev/watchdog with major number 10 and minor
11 number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
12 subsequently opening the file and then failing to write to it for

22 The watchdog is usually used together with the watchdog daemon
23 which is available from

25 also monitor NFS connections and can reboot the machine when the process

772 When "Watchdog Timer Value" enabled one can set 31-255 s operational range.

774 Entering BIOS setup temporary disables watchdog operation regardless to current state,
775 so system will not be restarted while user in BIOS setup.

1538 so that the timer has a chance to clear the overflow counter. On
1539 slower systems (such as the SH-2 and SH-3) this will likely yield
1540 some performance issues. As such, the WDT should be avoided here
