8 If you say Y here (and to one of the following options) and create a
9 character special file /dev/watchdog with major number 10 and minor
10 number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
11 subsequently opening the file and then failing to write to it for
12 longer than 1 minute will result in rebooting the machine. This
13 could be useful for a networked machine that needs to come back

16 reboot the machine) and a driver for hardware watchdog boards, which
17 are more robust and can also keep track of the temperature inside

21 The watchdog is usually used together with the watchdog daemon
22 which is available from
23 <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
24 also monitor NFS connections and can reboot the machine when the process
25 table is full.

34 The default watchdog behaviour (which you get if you say N here) is
35 to stop the timer if the process managing it closes the file
36 /dev/watchdog. It's always remotely possible that this process might
37 get killed. If you say Y here, the watchdog cannot be stopped once
38 it has been started.

1092 This is the driver for the Berkshire Products ISA-PC Watchdog card.
1093 This card simply watches your kernel to make sure it doesn't freeze,
1094 and if it does, it reboots your computer after a certain amount of
1095 time. This driver is like the WDT501 driver but for different
1096 hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC
1097 watchdog cards can be ordered from <http://www.berkprod.com/>.

1123 otherwise N. It is not possible to probe for this board, which means
