Hopefully someone else can come along and help you (I can't =(, sorry), but until then, check this out:
http://wiki.osdev.org/Loopback_Device#Creating_an_image. It may do what you need.

Hello Raynesax,
I myself also use linux and I use this code to put my bootloader on a floppy:
I DO have a floppy drive thats what this code is aimed for!
But you could create a empty floppy image and mount it and then write to it
Here's a little example (Taken from James Molloy's website)
You need /sbin in your $PATH for losetup to work!
Code: Select all
sudo losetup /dev/loop0 floppy.img
sudo mount /dev/loop0 /mnt
sudo cp src/kernel /mnt/kernel
sudo umount /dev/loop0
sudo losetup -d /dev/loop0
This script is ofcourse for his tutorial series but with the code I gave you earlier you could write them together and work that way
Hope I was of any help!
