Make the blank screen saver work with MDA and CGA. The fade and green
savers are also modified so that they behave in the same way as the blank saver on MDA and CGA, although it's not the way these screen savers are supposed to work, but fading monitor and tickling green monitor cannot be done on MDA and CGA, AFAIK. So, this is the second best solution. As of this change, the current state of support of screen savers is summarized in the following table. MDA CGA EGA VGA blank OK OK NA OK daemon OK OK OK OK fade * * NA OK green * * NA OK snake OK OK OK OK star OK OK OK OK OK: works NA: doesn't work, the module cannot be loaded for this adapter. *: behave the same way as the blank saver. As you can see, EGA is left out for now. But, we can do no better, as EGA registers cannot be read... Reviewed by: sos
