You could borrow bximage from Bochs too to generate them easily :D.

Or in a Unix platform, with just dd and vnconfig under OpenBSD or kpartx under Linux.

    >dd if=/dev/zero of=a.img bs=1440k count=1

    >vnconfig vnd0 a.img

    >newfs_msdos -F 12 /dev/rvnd0c

    >vnconfig -u vnd0

    >file a.img

a.img: x86 boot sector

That's under OpenBSD, under Linux is similar.

As far as i can tell bximage can only create empty images, which isn't what i was after (86box, the fork of PCem i am using, has a command to generate empty images too). What i wrote about was creating floppy image files with files inside them.

Also i'm using Windows and wanted a GUI tool.
