    attention, I don't know what will... (nonblinking 'transparent'

    that blinks at twice the rate....)

    On the standard VGA, the [hardware] cursor color is obtained
    from the foreground color of the character that the cursor is
    superimposing. On the standard VGA, there is no way to modify
    this behavior.
