   6         bool "Watchdog Timer Support"
   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 <file:Documentation/watchdog/watchdog.txt>
  19           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.

  32         bool "Disable watchdog shutdown on close"
  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.

 787           /dev/temperature yields one byte, the temperature in degrees
 788           Fahrenheit. This works only if you have a PCI-WDT501 watchdog board
 789           installed.

 791           If you want to enable the Fan Tachometer on the PCI-WDT501, then you
 792           can do this via the tachometer parameter. Only do this if you have a
 793           fan tachometer actually set up.

 806           This is the driver for the Berkshire Products USB-PC Watchdog card.
 807           This card simply watches your kernel to make sure it doesn't freeze,
 808           and if it does, it reboots your computer after a certain amount of
 809           time. The card can also monitor the internal temperature of the PC.

 812           To compile this driver as a module, choose M here: the
 813           module will be called pcwd_usb.

 815           Most people will say N.
