When this option is selected, it enables an extra 128K of memory in an area normally reserved for system use from 832K-960K or D000H-EFFFH. Split memory can be enabled only if the starting address on the board is 128K or 256K. Also, this memory must be accessed directly; it is not available to the operating system. The table below shows the four memory configurations supported with split memory. One of them (576K) is a standard configuration and may be used with or without the split memory option.
