This error occurs because the programs you're trying to run happen to require more than the 640KB of usable memory that MS-DOS has access to by default. (Optional) Fixing the "Not Enough Memory" Error If, after the steps above, booting into MS-DOS now allows you to see your programs, but attempting to run them results in a Not Enough Memory error, follow the step below to solve it. Once you're done, you should now be able to see and boot your programs in MS-DOS. I prefer WinSetupFromUSB for this part of the process. mds files serve, but for ours at least, it can be discarded.įrom here on, you can use your bootable media creator as normal to create your bootable USB or CD, using the image that we just created as a source.

Note that although I only tested this process using MS-DOS 6.22, the process outlined below should be identical for any version of MS-DOS so long as you download and use the boot disk for your intended version. Instead, the programs need to be "injected" directly into the boot disk, from which an ISO can then be made.īelow is a longer guide to the process, as well as the solution to the memory problem you may run into when trying to run the newly-visible programs in DOS. For whatever reason, this doesn't change the files available to you once booted into MS-DOS. In short, my initial mistake was packaging the executables into the ISO directly. Booting into MS-DOS 6.22 worked, but just as it had done when I used the unaltered boot ISO, displayed only the 40 files that came packaged with DOS 6.22 by default, completely ignoring the extra files I added to the new ISO.Īfter a lot of work, research and guidance from I finally managed to accomplish the goal of packaging the legacy executables I needed into an ISO and successfully run them from within MS-DOS 6.22. Inserting the flash drive booted into grub4DOS as it should have. The operation ran successfully, and I used WinSetupFromUSB to load the newly-created ISO onto a bootable flash drive. I then added ISO9660 and UDF volume labels, and selected the Build button.
I downloaded the boot floppy/diskette image for DOS 6.22 ( Dos6.22.img) from here, and selected it as the Boot Image in Advanced > Boot Manager, with the below settings: I then opened ImgBurn's Build mode, and then selected the 40 DOS files and my executables as the source, totalling 57 files. To do this, I extracted all 40 files from the original boot disk ISO using WinRAR.
