Hi all, I'm trying to run a DOS program under Linux, and have tried these: DOSbox: fails because the program needs SHARE.EXE QEMU/FreeDOS: fails immediately with message about interrupt QEMU/MS-DOS 6.22: fails after a while with internal error code DosEMU (2): fails after a while with same internal error code Virtualbox/MS-DOS 6.22: works However, I need to get data in and out, so Virtualbox is not optimal, and I'd like it to be simple and minimal, like QEMU. Are there any other options? /Tomas
