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

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

676 ---help---
677 Hardware driver for the TCO timer built into the nVidia Hub family
678 (such as the MCP51). The TCO (Total Cost of Ownership) timer is a
679 watchdog timer that will reboot the machine after its second
680 expiration. The expiration time can be configured with the
681 "heartbeat" parameter.
682
683 On some motherboards the driver may fail to reset the chipset's
684 NO_REBOOT flag which prevents the watchdog from rebooting the
685 machine. If this is the case you will get a kernel message like
686 "failed to reset NO_REBOOT flag, reboot disabled by hardware".

705 This driver can be used with the watchdog timer found on some
706 single board computers, namely the 6010 PII based computer.
707 It may well work with other cards. It reads port 0x443 to enable
708 and re-set the watchdog timer, and reads port 0x45 to disable
709 the watchdog. If you have a card that behave in similar ways,
710 you can probably make this driver work with your card as well.
