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
24 <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
25 also monitor NFS connections and can reboot the machine when the process
26 table is full.

1030 It`s possible to enable watchdog timer either from BIOS (F2) or from booted Linux.
1031 When "Watchdog Timer Value" enabled one can set 31-255 s operational range.
1032
1033 Entering BIOS setup temporary disables watchdog operation regardless to current state,
1034 so system will not be restarted while user in BIOS setup.
1035
1036 Once watchdog was enabled the system will be restarted every
1037 "Watchdog Timer Value" period, so to prevent it user can restart or
1038 disable the watchdog.

1973 This is a driver for the Mixcom hardware watchdog cards. This
1974 watchdog simply watches your kernel to make sure it doesn't freeze,
1975 and if it does, it reboots your computer after a certain amount of
1976 time.

1987 If you have a WDT500P or WDT501P watchdog board, say Y here,
1988 otherwise N. It is not possible to probe for this board, which means
1989 that you have to inform the kernel about the IO port and IRQ that
1990 is needed (you can do this via the io and irq parameters)
