Then the PGN game probably did not contain any score information. During 
game load
the engine is not active; XBoard just displays the game as loaded.

There is no need to specify an initial mode; you can load the game, move 
to the start
posiiton of it, (<< button), and then select Analyze Game. In Analyze 
Game mode
it does run the engine, to annotate the game with its output during the 
auto-stepping,
and because the game then will have scores in it, you will see them in 
the Eval Graph.
