Booting from a floppy

Hi I just try this latest Autoyast, wondering why the docs say it's recommended not to use a simple boot disk to initiate the install. Seems there've to be some (large) packages on the initial boot media!? Could anyone explain why? I don't want to use a CD or another bigsize media to initiate. All the installation data should be available via nfs or ftp, so why is it needed (from the docs: "... is limited due to the size of the data a floppy can hold"). If it's really not possible how do I use Autoyast without any CD or PXE available at the client machines? Thanks in advance, Jens
