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.:

16 reboot the machine) and a driver for hardware watchdog boards, which

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.

42 The default watchdog behaviour (which you get if you say N here) is
43 to stop the timer if the process managing it closes the file
44 /dev/watchdog. It's always remotely possible that this process might
45 get killed. If you say Y here, the watchdog cannot be stopped once

Wim Van Sebroeck9b901ee2009-06-19 09:32:57 +00001399 If you have a PCI-WDT501 watchdog board then you can enable the
1400 temperature sensor by setting the type parameter to 501.

1402 If you want to enable the Fan Tachometer on the PCI-WDT501, then you
1403 can do this via the tachometer parameter. Only do this if you have a
1404 fan tachometer actually set up.

1420 This is the driver for the Berkshire Products USB-PC Watchdog card.
1421 This card simply watches your kernel to make sure it doesn't freeze,
1422 and if it does, it reboots your computer after a certain amount of
1423 time. The card can also monitor the internal temperature of the PC.
