I thought someone had sent me a fix for this in the distant past, but I can't find the "MSDOSxxx" label in the source. However the custom generator should be easy to fix: https://gitlab.com/nbdkit/nbdkit/-/blob/a2fe619c45a97fd89063cc8d9106264c5adf6018/plugins/floppy/virtual-floppy.c#L454 https://gitlab.com/nbdkit/nbdkit/-/blob/a2fe619c45a97fd89063... However one definite restriction is it only serves FAT32 (not FAT16), which would be a dealbreaker for really old guests like this.
