Hi,
I have been working on multi booting for some time and let me say that
Microsoft has NEVER made life easy for we who try. The first install of
freedos will write the loader info in the MBR. If you install something else
in the same partition you will overwrite the existing loader. According to
stuff I read years ago, you need a boot manager which is what you are trying to
get. The easiest boot manager I love to use is grub4dos. I usually load it
via puppy linux (very small os) and install puppy at the end of the disc. once
it is installed you can have work with the menu.lst to control how the various
systems are to be loaded. Another thing I remember is that if you want dos in
its own partition you need to hide its partition when you are using some other
one, because dos gets confused if it is available. I have tried to make the
first partition a puppy one, but you want the menu.lst file to reside on a fat
partition so everyone can see it. I found out that using grub4dos and hiding
and unhiding partitions allows each system to think it has the whole systen o
itself (which it does - except that the system is only its own partition and
any other partitions which are unhidden fat partitions).

I let the installer work under Qemu. FreeDOS was installed
to the first part of the drive. Part 1 of Qemu parameter /dev/sdb.
Ie. /dev/sdb1
Then rebooted and FreeDOS came to life. Good. =8~)
Still wanted to multiboot and therefore installed Boot Manager.
That allowed booting Oberon in /dev/sdb2.
So the FreeDOS installer didn't cobber /dev/sdb2.
Then tried booting FreeDOS via Boot Manager. No luck.
Screenshot here. https://easthope.ca/BootManager.jpg
Note "Loading FreeDOS No KERNEL sys".
Anyone else have FreeDOS working in a multiboot setup?
Ideas? Any clues in the screenshot?
Thx, ... P.
