	This is a VGA issue (including SVGA).  The screen border (the
displayed portion of the screen that you cannot write your own pixels in) 
is always displayed in color 0 in paletted modes and black in non-paletted
modes.  Unfortunately, the only way AFAIK to make sure the border is black
is to rearrange your palette such that color 0 is black.
