   Seeing as how I just did this procedure myself and it's fresh in
my mind...
   The manual says definitely NOT to use 768K on the board.  Fill the
bottom row all the way or not at all.  If you put 512K on the board
(top row full), close the LOWER jumper.  If you fill the board, close
BOTH jumpers.  It's that simple.  The DRAMS you're using should be
fine.
