Question about which tools to use, bugs, the best way to implement a function, etc should go here. Don't forget to see if your question is answered in the wiki first! When in doubt post here.
Above is a grub formated floppy, replace kernel.bin and it should boot fine. If you are on windows use rawwrite or similar to write to a physical disk.
You have file management utilities that work on images.
On linux you can use the loopback device, you can compile and use mtools on windows. That way you can replace the kernel binary without having to write to disk.

Another great tool for windows is vfd (download) which allows you to mount a disk image as a virtual floppy drive. Bochs can then boot from this drive as if there was a real floppy disk. The tool also saves you from having to patch your image with a new kernel as it allows you to access the files nativly from your explorer.
