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

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

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

1384 This is the driver for the Berkshire Products ISA-PC Watchdog card.
1385 This card simply watches your kernel to make sure it doesn't freeze,
1386 and if it does, it reboots your computer after a certain amount of
1387 time. This driver is like the WDT501 driver but for different
1388 hardware. Please read <file:Documentation/watchdog/pcwd-watchdog.txt>. The PC
1389 watchdog cards can be ordered from <http://www.berkprod.com/>.

1391 To compile this driver as a module, choose M here: the
1392 module will be called pcwd.

1400 This is a driver for the Mixcom hardware watchdog cards. This
1401 watchdog simply watches your kernel to make sure it doesn't freeze,

1414 If you have a WDT500P or WDT501P watchdog board, say Y here,
1415 otherwise N. It is not possible to probe for this board, which means
1416 that you have to inform the kernel about the IO port and IRQ that
1417 is needed (you can do this via the io and irq parameters)
1418
1419 To compile this driver as a module, choose M here: the
1420 module will be called wdt.

Wim Van Sebroeck9b901ee2009-06-19 09:32:57 +00001450 If you have a PCI-WDT501 watchdog board then you can enable the
1451 temperature sensor by setting the type parameter to 501.

1453 If you want to enable the Fan Tachometer on the PCI-WDT501, then you
1454 can do this via the tachometer parameter. Only do this if you have a
1455 fan tachometer actually set up.
