Recently, I’ve needed to create DOS floppy images to use with
VMWare. Floppy images end up being more convenient than trying to set
up LANMAN or other networking in DOS. I used to use
dd(1), but it’s
come to my attention that the
mkfs.vfat(8) now has a -C option, that
does some of that hard work for you.
mkfs.vfat -C "myfloppy.img" 1440 mount -o loop -t vfat ./myfloppy.img /mnt
Near as I can tell, these images work great with DOS 6.2. I’m not quite sure on earlier versions.
