            Note: Board accepts EDO memory. The table reflects only some
            of the possible configurations. Rules follow: 1) when only
            SIMM bank 0 is filled, DIMM bank 2 or DIMM banks 2 & 3 can be
            used, and 2) when SIMM banks 0 & 1 are both filled, only DIMM
            bank 3 can only be used.
