+          This is the driver for the built-in watchdog timer on the fit-PC2,
+          fit-PC2i, CM-iAM single-board computers made by Compulab.
 
           It`s possible to enable watchdog timer either from BIOS (F2) or from booted Linux.
           When "Watchdog Timer Value" enabled one can set 31-255 s operational range.
