=== Floppy Disk Images With GRUB and EXT2 ===
First, lets create

Line 69:
mount -t msdos /dev/loop0 /mnt/myfloppy
=== Floppy Disk Images With FAT12 ===
The steps mentioned below will be useful for the BrokenThorn Entertainment tutorials
Create an empty image.
dd if=/dev/zero of=floppy.img bs=512 count=2880▼
Set it up for mounting.
Format it to FAT12.
mkdosfs -F 12 /dev/loop0
Mount!
mount /dev/loop0 /mnt -t msdos -o "fat=12"
Unmount
Destroy loopback device
losetup -d /dev/loop0

Note: mke2fs is smart enough to figure out block size and #blocks for itself, but if you ever want to use multiple partitions you'll need to know how to use those values.

== Loopback Device under FreeBSD ==
FreeBSD uses mdconfig. First, use DD to create an empty floppy image (1.44 MB in size). Memdisks are allocated dynamically, and the name is displayed after the mdconfig command. This assumes that "md0" is printed.

▲ vnconfig vn0 floppy.img
▲ umount /mnt/myfloppy
