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 | |
e0845bf4 | 15 | on-line as fast as possible after a lock-up. There's both a watchdog |
1da177e4 LT |
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 | |
e403149c DH |
19 | your computer. For details, read |
20 | <file:Documentation/watchdog/watchdog-api.txt> in the kernel source. | |
1da177e4 LT |
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. | |

1664 | This is the driver for the Berkshire Products PCI-PC Watchdog card. | |
1665 | This card simply watches your kernel to make sure it doesn't freeze, | |
1666 | and if it does, it reboots your computer after a certain amount of | |
1667 | time. The card can also monitor the internal temperature of the PC. | |

1681 | If you have a PCI-WDT501 watchdog board then you can enable the |
1682 | temperature sensor by setting the type parameter to 501. | |

1683 | |
1684 | If you want to enable the Fan Tachometer on the PCI-WDT501, then you | |
1685 | can do this via the tachometer parameter. Only do this if you have a | |
1686 | fan tachometer actually set up. | |
