	  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.

	  This driver adds watchdog support for the integrated watchdog in the
	  SuperH processors. If you have one of these processors and wish
	  to have watchdog support enabled, say Y, otherwise say N.

	  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 card simply watches your kernel to make sure it doesn't freeze,
