By default, XBoard tries to use Fairy-Max by running the command “fairymax”. That’s why if you don’t have Fairy-Max, you get the error message “Failed to start first chess program fairymax on localhost: fairymax: No such file or directory.” If you have GNU Chess 5, the command should be “gnuchess xboard” instead.
