Occasionally need to create floppy image, and an easy way to do it is to use Linux to create it. And you can mount it right there to add any files to it to.
The following command is to create a blank floppy, filled with zero.
/bin/dd if=/dev/zero of=/root/BlankFloppy.flp bs=512 count=2880
And this blank floppy can be formatted in Linux too.
/sbin/mkfs.vfat -v -c /root/BlankFloppy.flp
Mount the floppy image so that you can put files into it.
mount -o loop /root/BlankFloppy.flp /media/floppy
In Windows, you can use some Winimage, Floppyimage, undisker to create image of floppy.
