Configuration of the Watchdog card

Note: To use the reset and automatic startup, ensure that the Reset

button signals the PC to restart, instead of signalling Windows to restart.

If the reset button signals for Windows to restart, and Task Manager is

running, Task Manager blocks the restart command.
