This section is geared to users who thoroughly understand the preceding information, and would like to learn some more advanced techniques for gaining the optimum amount of memory. The MEM command, which you run from the DOS prompt, shows the amount of memory that is available in the different areas of the system. The MEM command displays the locations and sizes of all loaded programs. By looking at the list of programs in Figure 6, you can see which programs are still being loaded into conventional memory. In Figure 6 are several pieces of information.
Regions are basically upper memory blocks.
This created an additional block of memory in the upper memory area. The addresses located within this range are represented in Figure 7, as well as other blocks of memory that EMM386 has found. In all, Figure 7 shows four regions, or four different UMBs, into which programs can be loaded. Armed with this information, you can selectively load programs into different regions of memory. This size is too small for relocating any more moveable files.
