Four additional shadow options allow you to shadow 32KB at
the memory addresses listed
on
the screen. You may want to
enable one or more of these shadow options if, for example,
you are using option cards that contain ROM. You
can
shadow
the memory on the card to your system’s RAM using these
options. Check the memory map on page A-6 and the
documentation that came with your option card to determine
which addresses your option card can access. You may also
need to set some switches or jumpers on the option card.
