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.

1341 This is the driver for the hardware watchdog on the W83977F I/O chip
1342 as used in AAEON's PCM-5335 SBC (and likely others). This
1343 watchdog simply watches your kernel to make sure it doesn't freeze,
1344 and if it does, it reboots your computer after a certain amount of
1345 time.

1369
1370 *Note*: This hardware watchdog is not probeable and thus there
1371 is no way to know if writing to its IO address will corrupt
1372 your system or have any real effect. The only way to be sure
1373 that this driver does what you want is to make sure you
