I developed a DOS program using Clipper 8 years ago, there were many users of it and look very satisfied already using it. however, since we can't stop people from upgrading hardwares and softwares, the installation of Windows ME and 2000 gave a bit of a problem in running my DOS program. The program needs some DOS environment settings under autoexec.bat and config.sys in order for it to run properly. But it seems that WinME is not using these files upon start-up, unlike Win98 and older OS. In this case, with your kind hearts and technical know-how, I would like to seek your help regarding "HOW TO SET AUTOEXEC.BAT AND CONFIG.SYS UNDER WINDOWS ME and later OS?". I would greatly appreciate any help that you may offer to me. Thank you very much and more power!!!

No technical no-how, but I thought this interesting and maybe of use to you: http://www.geocities.com/mfd4life_2000/

Modification to Windows ME to support back level DOS might cause problems on your users systems. So avoid that method if possible. Most DOS based applications will work on Windows ME without any special setup. You just can't do it through the old Config.sys and Autoexec.bat files. What you need to do is set up a new Short Cut on the DeskTop to the programs BAT, COM or EXE file. Then edit the Program tab for any additions required on the CMD line to start it (parameters picked up by the program), Set its working directory if different from its load directory. And then create a Batch file with any of the statements that are still required to run in the AUTOEXEC.BAT such as SET statments that were in the old autoexec.bat file and enter its path and name into the Batch file line, so that it runs when the DOS VDM is started. If you need a specific size Environment this can be set in the Memory section. Windows ME should detect and automatically support most memory management requirements, and provide standard interfaces to devices like CD-ROM. Your only problems come in if you require special hardware drivers or a few of the old DOS mode SYS files. Microsoft has a very good write ups on different parts of this including Config.sys restricions list.

...Also, remember, as part of the program exiting, to add a .bat file or within the program itself, add apropriate cmd's for restoring the original settings/environment.
