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.

29 If unsure, say N.

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.

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

571 Saying Y here and creating a character special file /dev/temperature
572 with major number 10 and minor number 131 ("man mknod") will give
573 you a thermometer inside your computer: reading from
574 /dev/temperature yields one byte, the temperature in degrees
575 Fahrenheit. This works only if you have a PCI-WDT501 watchdog board
576 installed.
577
578 If you want to enable the Fan Tachometer on the PCI-WDT501, then you
579 can do this via the tachometer parameter. Only do this if you have a
580 fan tachometer actually set up.
