Okay, this maybe the dumbest question.  But I found some source
code to write to the video card usingt he VESA...blah...blah.
and once switched to the mode, it sets up a selector using the PhysbasePtr,
with*height of the mode, stuff like that.

to write to the screen it uses a command called _farpokeb or something like
that.  Anyway, I was wondering,  how can you address the base memory fromt
he selector?


say the selector is  VideoRam, its type is an Int and its not a pointer, so
you can do this  VideoRam[place on screen] = color
so, how do you do it without that poke thingy?
