  8         ---help---
  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
 15           on-line as fast as possible after a lock-up. There's both a watchdog
 16           implementation entirely in software (which can sometimes fail to
 17           reboot the machine) and a driver for hardware watchdog boards, which
 18           are more robust and can also keep track of the temperature inside
 19           your computer. For details, read
 20           <file:Documentation/watchdog/watchdog-api.txt> in the kernel source.
 21 
 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.

 28           If unsure, say N.

 34         ---help---
 35           Say Y here if you want to use the new watchdog timer driver core.
 36           This driver provides a framework for all watchdog timer drivers
 37           and gives them the /dev/watchdog interface (and later also the
 38           sysfs interface).

 40 config WATCHDOG_NOWAYOUT
 41         bool "Disable watchdog shutdown on close"
 42         help
 43           The default watchdog behaviour (which you get if you say N here) is
 44           to stop the timer if the process managing it closes the file
 45           /dev/watchdog. It's always remotely possible that this process might
 46           get killed. If you say Y here, the watchdog cannot be stopped once
 47           it has been started.

1143           *Note*: This hardware watchdog is not probeable and thus there
1144           is no way to know if writing to its IO address will corrupt
1145           your system or have any real effect.  The only way to be sure
1146           that this driver does what you want is to make sure you
1147           are running it on an EPX-C3 from Winsystems with the watchdog
1148           timer at IO address 0x1ee and 0x1ef.  It will write to both those
1149           IO ports.  Basically, the assumption is made that if you compile
1150           this driver into your kernel and/or load it as a module, that you
1151           know what you are doing and that you are in fact running on an
1152           EPX-C3 board!

1532           and if it does, it reboots your computer after a certain amount of
1533           time. This driver is like the WDT501 driver but for different
1534           hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC
1535           watchdog cards can be ordered from <http://www.berkprod.com/>.

1546           This is a driver for the Mixcom hardware watchdog cards.  This
1547           watchdog simply watches your kernel to make sure it doesn't freeze,
1548           and if it does, it reboots your computer after a certain amount of
1549           time.

1560           If you have a WDT500P or WDT501P watchdog board, say Y here,
1561           otherwise N. It is not possible to probe for this board, which means
1562           that you have to inform the kernel about the IO port and IRQ that
1563           is needed (you can do this via the io and irq parameters)

1579           This is the driver for the Berkshire Products PCI-PC Watchdog card.
1580           This card simply watches your kernel to make sure it doesn't freeze,
1581           and if it does, it reboots your computer after a certain amount of
1582           time. The card can also monitor the internal temperature of the PC.

1595 
1596           If you have a PCI-WDT501 watchdog board then you can enable the
1597           temperature sensor by setting the type parameter to 501.
1598 
1599           If you want to enable the Fan Tachometer on the PCI-WDT501, then you
1600           can do this via the tachometer parameter. Only do this if you have a
1601           fan tachometer actually set up.
1602 
1603           To compile this driver as a module, choose M here: the
