DOS emulators

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?
