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

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

683 ---help---
684 Hardware driver for the TCO timer built into the nVidia Hub family
685 (such as the MCP51). The TCO (Total Cost of Ownership) timer is a
686 watchdog timer that will reboot the machine after its second
687 expiration. The expiration time can be configured with the
688 "heartbeat" parameter.
689
690 On some motherboards the driver may fail to reset the chipset's
691 NO_REBOOT flag which prevents the watchdog from rebooting the
692 machine. If this is the case you will get a kernel message like
693 "failed to reset NO_REBOOT flag, reboot disabled by hardware".

712 This driver can be used with the watchdog timer found on some
713 single board computers, namely the 6010 PII based computer.
714 It may well work with other cards. It reads port 0x443 to enable
715 and re-set the watchdog timer, and reads port 0x45 to disable
716 the watchdog. If you have a card that behave in similar ways,
717 you can probably make this driver work with your card as well.
718
719 You can compile this driver directly into the kernel, or use
720 it as a module. The module will be called sbc60xxwdt.

1151 to have watchdog support enabled, say Y, otherwise say N.

1154 so that the timer has a chance to clear the overflow counter. On
