OSDev.org

I've been trying to get my osdev environment (GRUB, and my simple kernel.bin) setup on my new Linux system, but have been having troubles with my lack of floppy drive. I created a floppy image. (A simple file.) Yet, to copy my kernel to / of the mounted file, I have to mount the image under root, and then copy the file over, which means that I can't test my OS under my normal user.

Is there any way to copy a file into a virtual file system without using root or any real hardware? Any ideas?

Edit: Reading the wiki might have been a good idea. mcopy was what I needed...Sorry...
