The following will help allow your computer to load programs into memory more efficiently allowing you to have more memory for MS-DOS programs / games.
Ensure you have the following lines at the beginning of your config.sys file.
DEVICE=C:\WINDOWS\HIMEM.SYS
DOS=HIGH,UMB
DEVICE=C:\WINDOWS\EMM386.EXE NOEMS
By placing the DOS=HIGH,UMB on the second line this can in some cases save memory because it is loading DOS into upper memory before loading the memory manager. Additionally the first and third line cannot be loaded into high memory because these lines are the memory managers.
Load all your devices in your config.sys and autoexec.bat into high memory.
How can I comment lines in batch or system files?
Remarking lines within the autoexec.bat or the config.sys allows you to temporarily or permanently prevent a line from loading each time you boot the computer. The method most commonly used is placing "REM " in front of the file you wish to skip.
REM PATH=C:\WINDOWS
If you are encountering issues with a line in the autoexec.bat it is highly recommended that you remark the line instead of removing it. This will prevent issues from arising if the line needs to be placed back into the appropriate file.
