Hi Jim,
I am working with primarily arm computers (Raspberry Pi primarily) and as of 
now the virtualization is poor to nonexistent.  Since I have several programs I 
worked with when I was employed (before retirement) I ended up with a couple of 
dell thin systems which also are short on the memory and speed for using a 
virtual system.  So I stay with my multi-boot process and it seems to work for 
me.  One thing I do not understand is why I install FreeDOS-Live onto one of my 
x86 systems and it uses eltorito to do the install and no problems.  Next I 
boot from the hard drive and running the same exact code as was used during 
install it cannot find the cdrom at this time. I am hitting my head against a 
brick wall as to what I am doing wrong.

Using a boot manager is an excellent idea when you need to boot
multiple operating systems from one physical PC. I used to do this all
the time from the 1990s to the early 2000s to try out different
things.

But the idea of a virtual machine is to *isolate* operating systems to
their own virtual space. With a virtual machine system like QEMU, you
don't need to use multiboot -- just set up one virtual machine for
FreeDOS, and a new virtual machine to run Oberon.

While multiboot should work, you seem to be making this harder than it
needs to be.

Maybe you answered this in a previous email (I'm starting to get
caught up on email) but why not set up a separate virtual machine for
Oberon?
