Making Diskette Images without Diskettes

So far we have been preparing boot diskettes by writing to real diskettes. This sounds like the most logical way to do it, but there can be reasons why we want to prepare an image file of a diskette without using real diskettes. Several reasons could be:

Basically we could create a diskette image as follows:

The last part is the trickiest especially for LILO. It's fairly trivial for SYSLINUX and using the device command it can be done with GRUB. There is also another trick for SYSLINUX and GRUB (it does not work with LILO):

On Timo's Rescue CD Page there is a good explanation of how to create 2.88MB diskette images for a bootable CD-ROM, using all boot loaders. I could not explain it better. Of course these recipes apply also to other types of disk images.
