Ray,
Sorry, but I did read around first. I made a boot floppy off the CD. But it is just an install floppy and not, as far as I can see, a rescue one.
I think that the rescue floppy that the install generates (and is generated from your command that you supplied) is a bit different, having enough additional information to boot a running server (there are various posts with people using a boot floppy to get past lilo).
