 *
 *	To enable Watchdog function:
 *	 1. BIOS
 *	  For P4SBx:
 *	  BIOS setup -> Advanced -> Integrated Peripherals -> Watch Dog Feature
 *	  For P4DPx:
 *	  BIOS setup -> Advanced -> I/O Device Configuration -> Watch Dog
 *	 This setting enables or disables Watchdog function. When enabled, the
 *	 default watchdog timer is set to be 5 minutes (about 4m35s). It is
 *	 enough to load and run the OS. The application (service or driver) has
 *	 to take over the control once OS is running up and before watchdog
 *	 expires.
 *
 *	 2. JUMPER
 *	  For P4SBx: JP39
 *	  For P4DPx: JP37
 *	  This jumper is used for safety.  Closed is enabled. This jumper
 *	  prevents user enables watchdog in BIOS by accident.
 *
 *	 To enable Watch Dog function, both BIOS and JUMPER must be enabled.
 *
 *	The documentation lists motherboards P4SBx and P4DPx series as of
 *	20-March-2002. However, this code works flawlessly with much newer
 *	motherboards, such as my X6DHR-8G2 (SuperServer 6014H-82).
 *
 *	The original iTCO driver as written does not actually reset the
 *	watchdog timer on these machines, as a result they reboot after five
 *	minutes.
 *
 *	NOTE: You may leave the Watchdog function disabled in the SuperMicro
 *	BIOS to avoid a "boot-race"... This driver will enable watchdog
 *	functionality even if it's disabled in the BIOS once the /dev/watchdog
 *	file is opened.
