I'm able to set the display into graphics mode by using the VIO functions.
However, the function to get the selector for the screen fails with an
"invalid display mode" message. How can I write graphics directly to the
screen? All I need is the selector to the screen ram, how do I obtain it?

This is not a PM program.
