Well this is a complicated question.  If your using Allegro then it's
really easy but I suspect you mean without Allegro.  A default pointer
is provided only in standard VGA modes by the mouse driver.  For all
other modes (SVGA / VESA modes) you must hook into or poll the mouse
driver to get information about the current (x,y) coordinate of the
mouse pointer.  This is a whole other subject completely.  After
getting current pointer location you then have to draw the mouse on
the screen.  But this is only in non-VGA modes.  If you want a pointer
in Mode 13h then just initalize the mouse driver and it will magically
appear.  Check out Ralf Brown's interrupt list for exact details on
all this.
