	  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

	  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.

	  As a side note, saying Y here will automatically boost HZ to 1000
	  so that the timer has a chance to clear the overflow counter. On
	  slower systems (such as the SH-2 and SH-3) this will likely yield
	  some performance issues. As such, the WDT should be avoided here
	  unless it is absolutely necessary.

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

	  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.
