Hardware is sometimes better for running DOS, and sometimes a virtual
machine is better for running DOS. It really depends on what you are

For example, when I'm writing code for FreeDOS, I'll have a copy of
FreeDOS booted in DOSemu. I run Linux, with lots of nifty developer
tools and editors, and I just find it's easier for me to do my FreeDOS
work there (say, in GNU emacs) while I also have a web browser open
for email, or Facebook, or whatever. When it's time to compile, I just
bring up the DOSemu window and compile under FreeDOS.

Doing this in DOSemu is great for my coding because DOSemu can boot an
instance of FreeDOS from a directory on Linux. So when I edit files
under Linux, I'm saving them to a directory under Linux, and they are
immediately visible to the FreeDOS session in DOSemu.

However, let's say I wanted to play DOS games. I might do that under
an emulator like DOSemu (and I have) but in certain cases the emulator
might just get in the way, not emulate the hardware as well as the DOS
game would like. So in that case, it would be better to set up a
dedicated PC to play those games. I've helped several friends to do
this, set up an older machine (which would otherwise be tossed out) to
play DOS games. That old PC may not run the latest version of Windows
very well, but it does a great job of playing DOS games.

Similarly, there are lots of cases where dedicated hardware is better.
Controllers, embedded systems, etc. all require actual hardware to do
the job. You wouldn't set up a Linux box just to run DOSemu + FreeDOS,
to support an embedded application.

You can do a multiboot system with FreeDOS on it, no problem. What
you've described would work. I used to use a program called PC
Commander (I think that was the name) that was a great multiple
operating system loader, and we used this at my work when we first
moved to Windows 95, long ago. GRUB, XaoS, and other free boot loaders
will do the same job.

My personal preference is: if I'm going to set up a hardware system
with FreeDOS on it, I'd rather it be a dedicated system. Nothing wrong
with doing a multiboot system, just my preference. Simpler that way,
less to go wrong.
