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.
