bool "Watchdog Timer Support" ---help--- If you say Y here (and to one of the following options) and create a character special file /dev/watchdog with major number 10 and minor number 130 using mknod ("man mknod"), you will get a watchdog, i.e.: subsequently opening the file and then failing to write to it for longer than 1 minute will result in rebooting the machine.

The watchdog is usually used together with the watchdog daemon which is available from <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can also monitor NFS connections and can reboot the machine when the process table is full. If unsure, say N. |

help The default watchdog behaviour (which you get if you say N here) is to stop the timer if the process managing it closes the file /dev/watchdog. It's always remotely possible that this process might get killed.

It`s possible to enable watchdog timer either from BIOS (F2) or from booted Linux. When "Watchdog Timer Value" enabled one can set 31-255 s operational range. Entering BIOS setup temporary disables watchdog operation regardless to current state, so system will not be restarted while user in BIOS setup. Once watchdog was enabled the system will be restarted every "Watchdog Timer Value" period, so to prevent it user can restart or disable the watchdog. To compile this driver as a module, choose M here: the module will be called sbc_fitpc2_wdt. Most people will say N. |
