Hi!

>> the installer has no way to install it as a multi boot choice.

We once had logics to add FreeDOS to Windows 98 and similar
boot menus to share one partition, but it has been a while
since Windows stopped using classic FAT and the logics are
too complex to automatically give the desired result in a
sufficiently large subset of existing installations. Compare
to Linux which can even resize Windows partitions and then
create a GRUB menu with Linux and Windows - a lot of effort!

It would be cool if somebody could give Tech Republic a hint
that FreeDOS is not at all limited to 2 GB partition sizes
but only to 2 TB harddisk size and MBR partition schemes ;-)

Note about my earlier comment: GPT partitioning is related
to UEFI but should not be confused with the OTHER problem
of UEFI which is "no BIOS interrupts available unless you
activate some legacy support / load some CSM at boot"...

If you already have GRUB, you can use SYS with suitable options
to generate a boot sector file to add FreeDOS to multi-boot in
situations where several systems will boot from your FAT16 or
FAT32 partition. If FreeDOS is the only operating system on your
FAT partitions, GRUB can automatically find and add it to the
boot menu when you run update-grub in Linux, as far as I know.

If you already have Windows on NTFS, you can probably edit the
Windows boot menu config while in Windows to add FreeDOS, but
I do not know the details about that.

In both cases, FreeDOS would have to manipulate files on NTFS
or Linux partitions to install itself without your manual help,
so it is good that FreeDOS does NOT do that at the moment ;-)

If you want a boot menu to select one of several operating
systems on a single FAT partition, check out my METAKERN
tool, but be aware that it is rather minimalistic, so you
will have to do all "figuring out" by hand to configure it.

Regards, Eric
