Personal Computer User Manual

The addresses of the gap or overlap are shown in hexadecimal
numbers. (Hexadecimal is a base-16 numbering system used in
programming.) The message tells you the starting and ending
addresses of the gap or overlap and recommends two starting
addresses for the memory you added on the memory card.
The first recommended starting address is the starting address of
the 384KB of on-board extended memory. The second
recommended starting address is the ending address of that
384KB of memory. If you reset your memory card to the first
recommended starting address, your system cannot use the
384KB of on-board extended memory in your configuration
since its address is used by memory on the memory card. By
choosing the second recommended starting address, you can
include the 384KB of memory in your configuration because the
memory you add on the memory card begins where the 384KB
of memory ends.
Some memory cards limit the possible starting addresses you can
set. See the manual that came with your memory card to
determine which starting address to use.
