Epson EL 486UC - Manual (Page 36)

Using Other Shadow Options
Eight additional shadow options are available, allowing you to
shadow 16KB at the memory address listed on the screen. You
may want to enable one or more of these shadow options if you
are using option cards that contain ROM. Using these options,
you can shadow the memory on the card to your system’s RAM
or external cache (if one is installed). Check 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 your option card.
If you enable the
Memory Remapping
option, you cannot
enable the last four of these
Shadow
options because they
access the same memory addresses.
