Based on your message, I would assume that PocketDOS is using its own format for Hard Disk Images which is down right silly. So, maybe do some searching on the internet to see if a conversion tool is available that will allow converting between formats. Otherwise, if since PocketDOS will support standard floppy disk images, you have another method. Create a PocketDOS VM. Use the modified FreeDOS Boot Floppy to boot straight to the command prompt. Partition and format the VM HDD. Use the SYS command to transfer the FreeDOS Kernel and FreeCOM. Boot the VM from the Virtual HDD, to make sure it boots to a command prompt and keyboard works. Now switch to Virtual Box and Create and Install FreeDOS. Copy tar to the floppy then onto PocketDOS. Now use tar to ‘archive’ all files on the VM to a Floppy. Use tar to ‘unarchive’ each floppy to PocketDOS. I cannot remember all of the features of the version of tar provided on FreeDOS 1.4. Namely if it supports disk spanning. So, either use the latest Interim Test build of FreeDOS available at https://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/test/ <https://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/test/> Or, download the current version of tar from the repository at https://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/repositories/1.4/html/en/archiver/tar/index.html <https://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/repositories/1.4/html/en/archiver/tar/index.html>
