    a boot floppy has a boot loader (grub or lilo) and is used to point to an
    existing kernel image (usually on the hdd). It can be used to boot a system
    that for some reason cannot boot from the hdd mbr. For example, I used to
    have a 486 that ran scsi drives but could not boot them with the (cheap) card
    I had, so i just left a boot floppy in the drive. The boot floppy had lilo
    point to the scsi drive for the os.

    A rescue disk will have it's own kernel and support files so it can boot linux
    without using anything from the hard drive. This would be used for example,
    if something happens like a fatal change to a file like inittab on the hard
    drive, preventing it from booting. You can boot with the floppy, possibly
    chroot into the hard drive, and fix whatever is broken.

    hope that helps.
