9 If you say Y here (and to one of the following options) and create a
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
13 longer than 1 minute will result in rebooting the machine. This
14 could be useful for a networked machine that needs to come back

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

804 When "Watchdog Timer Value" enabled one can set 31-255 s operational range.
805
806 Entering BIOS setup temporary disables watchdog operation regardless to current state,
807 so system will not be restarted while user in BIOS setup.
