   7         ---help---
   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
  14           on-line as fast as possible after a lock-up. There's both a watchdog
  15           implementation entirely in software (which can sometimes fail to
  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
  18           your computer. For details, read
  19           <file:Documentation/watchdog/watchdog-api.txt> in the kernel source.
  20
  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.
  26
  27           If unsure, say N.

  33         help
  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.

 817           are running it on an EPX-C3 from Winsystems with the watchdog
 818           timer at IO address 0x1ee and 0x1ef.  It will write to both those
 819           IO ports.  Basically, the assumption is made that if you compile
 820           this driver into your kernel and/or load it as a module, that you
 821           know what you are doing and that you are in fact running on an
