9 ---help---
10 If you say Y here (and to one of the following options) and create a
11 character special file /dev/watchdog with major number 10 and minor
12 number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
13 subsequently opening the file and then failing to write to it for
14 longer than 1 minute will result in rebooting the machine. This
15 could be useful for a networked machine that needs to come back
16 online as fast as possible after a lock-up. There's both a watchdog
17 implementation entirely in software (which can sometimes fail to
18 reboot the machine) and a driver for hardware watchdog boards, which
19 are more robust and can also keep track of the temperature inside
20 your computer. For details, read <file:Documentation/watchdog/watchdog.txt>
21 in the kernel source.
22
23 The watchdog is usually used together with the watchdog daemon
24 which is available from
25 <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
26 also monitor NFS connections and can reboot the machine when the process
27 table is full.

34 help
35 The default watchdog behaviour (which you get if you say N here) is
36 to stop the timer if the process managing it closes the file
37 /dev/watchdog. It's always remotely possible that this process might
38 get killed. If you say Y here, the watchdog cannot be stopped once
39 it has been started.

516 Say Y here to support the hardware watchdog capability on Sun RIO
517 machines. The watchdog timeout period is normally one minute but
518 can be changed with a boot-time parameter.

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

538 To compile this driver as a module, choose M here: the
539 module will be called pcwd.

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

573 Saying Y here and creating a character special file /dev/temperature
574 with major number 10 and minor number 131 ("man mknod") will give
575 you a thermometer inside your computer: reading from
576 /dev/temperature yields one byte, the temperature in degrees
577 Fahrenheit. This works only if you have a WDT501P watchdog board
578 installed.
579
580 If you want to enable the Fan Tachometer on the WDT501P, then you
581 can do this via the tachometer parameter. Only do this if you have a
582 fan tachometer actually set up.
