	  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. This
	  could be useful for a networked machine that needs to come back

	  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.

	  The default watchdog behaviour (which you get if you say N here) is

	  The TCO (Total Cost of Ownership) timer is a watchdog timer
	  that will reboot the machine after its second expiration. The
	  expiration time can be configured with the "heartbeat" parameter.

	  On some motherboards the driver may fail to reset the chipset's
	  NO_REBOOT flag which prevents the watchdog from rebooting the
	  machine. If this is the case you will get a kernel message like
	  "failed to reset NO_REBOOT flag, reboot disabled by hardware".

	  This is the driver for the hardware watchdog timers present on
	  Sun Microsystems CompactPCI models CP1400 and CP1500.

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

	  If you do not have a CompactPCI model CP1400 or CP1500, or
	  another UltraSPARC-IIi-cEngine boardset with hardware watchdog,
	  you should say N to this option.

	  Say Y here to support the hardware watchdog capability on Sun RIO
	  machines.  The watchdog timeout period is normally one minute but
	  can be changed with a boot-time parameter.

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

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

	  Most people will say N.

	---help---
	  If you have a WDT500P or WDT501P watchdog board, say Y here,
	  otherwise N. It is not possible to probe for this board, which means
	  that you have to inform the kernel about the IO port and IRQ that
	  is needed (you can do this via the io and irq parameters)

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

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

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