   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.

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

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

 846           Saying Y here and creating a character special file /dev/temperature
 847           with major number 10 and minor number 131 ("man mknod") will give
 848           you a thermometer inside your computer: reading from
 849           /dev/temperature yields one byte, the temperature in degrees
 850           Fahrenheit. This works only if you have a WDT501P watchdog board
 851           installed.
 852
 853           If you want to enable the Fan Tachometer on the WDT501P, then you
 854           can do this via the tachometer parameter. Only do this if you have a
 855           fan tachometer actually set up.
