Yep, you pretty much described the dosemu2, which was already mentioned
here. Itś a continuation of the old DOSEMU project. The original DOSEMU
relied on the V8086 virtualization mode that was introduced in the 386 CPU,
but V8086 mode isn't available in 64-bit (Long) mode. So instead, dosemu2

I am not sure if you really want to do that...

Hello Pablo,
Sorry, now I understand what you say. I also works on UML source code too.
Yes, UML intercepts system calls through ptrace, but instead of calling the
host kernel, it calls the UML kernel. Therefore, no host system call is
excecuted by the application process running

Hello Pablo,
User Mode Linux actually works more like dosemu than it may seem. UML
runs as a normal application under a host Linux system, of course. But
when you run, say, /bin/ls within a UML session, UML will indeed
intercept the syscalls made by the /bin/ls and transform them into the

Good day Pablo,
Unikernels: they are minimal Library operating systems embeded with the
application code. They provide networking, filesystem and virtual devices
support.
I think that if Linux could be converted in a executable (User Mode Linux) or
in a library (LKL), FreeDOS may also be

Hi PAP,
I assume unikernel means replacing hardware I/O by

DOS already does that by using BIOS. So you could
make a BIOS-Unikernel and then run FreeDOS as app
