Allegedly, Win10 doesn't come with a system MS-DOS (EBD) floppy image anymore, but older Windows like 7 have it in DISKCOPY.DLL (optionally used by RUFUS).

Creating a FAT image is easy on Win7 since it can mount such .VHD files into Explorer as a drive. (You can also use QEMU-IMG, but the one I tried was buggy, so Win7 didn't like it. I have no idea how to isolate that bug or to whom to report it.) Under Win7, I did so twice for MetaDOS (FAT16 and FAT32) and put both of them in HARDDISK.ZIP (albeit empty of any actual useful data).

Since 2014 (11.0), FreeBSD has also supported its own hypervisor (VT-X with EPT required), bhyve. But I've never used it. They also had a utility for disk creation / manipulation, but I forget the name (and a quick search doesn't show anything obvious).
