949 you a thermometer inside your computer: reading from
950 /dev/temperature yields one byte, the temperature in degrees
951 Fahrenheit. This works only if you have a WDT501P watchdog board
952 installed.

954 If you want to enable the Fan Tachometer on the WDT501P, then you
955 can do this via the tachometer parameter. Only do this if you have a
956 fan tachometer actually set up.
