                       MISCELLANEOUS TECHNICAL NOTE

            The board may be configured for any combination of
            conventional, expanded, and extended memory. When
            conventional memory is enabled, be sure to subtract 128KB
            from the remaining memory. When configured for both extended
            and expanded memory, be sure that the amount of extended
            memory is a multiple of 4MB.
