Memory Management
The best use of memory depends on the application that is using it, and the
types of memory available to the application.
Data storage
Drive E is recommended for data storage if less than 256K is
required. 1MB, 2MB, or 4MB SRAM PC cards are recommended if more
memory is required.
Applications and lookup tables
Drive E is recommended for storing all
applications and lookup tables. If more memory for applications is required, an
Intel flash block-erasable card, available in sizes of 1, 4, 10, and 20MB, is
recommended.
Large applications
If you develop a large application that requires more
conventional memory to run in than is presently available, remove any device
drivers and TSRs, such as ANSI.SYS or SRAMDISK.SYS, that are not required
by your application. If that still does not provide enough conventional
memory, then you might consider using HIMEM.SYS and EMM386 and load
some device drivers or TSRs into the upper memory blocks and high memory
area. Another possibility is purchasing a DOS extender and developing your
application so it can run using both conventional and extended memory.
See Chapter 11, “Advanced Operations,” for information on making more
conventional memory available on the JANUS 2050.
