DOS Memmaker Starting with DOS 6, Memmaker is a utility that optimizes memory on 386s and up by determining the best order to load TSRs and drivers in the upper memory area (UMA). Memmaker may change device= statements to devicehigh= in your CONFIG.SYS file in order to load drivers in the UMA. It may add the loadhigh command to TSRs loaded in your AUTOEXEC.BAT file to load them "high" as well. To run Memmaker, type memmaker. Choosing Express Setup will configure your system automatically. If certain TSRs and drivers placed in the upper memory area cause conflicts, you can exclude them by running Memmaker and choosing Custom Setup or by adding their names to the MEMMAKER.INF file. Use the DOS Editor to open MEMMAKER.INF and read the instructions. Choosing Custom Setup lets you specify further optimization. For example, if you use an EGA or VGA monitor and not Super VGA, answer Yes to "Use monochrome region for running programs." If you run only Windows applications, choose "No" to "Optimize upper memory under Windows?" Memmaker was eliminated in Windows 95. See DOS CHKSTATE.SYS and DOS SIZER.EXE.
