boot.img gone / how can we make and edited boot cd with 3kb for knoppix v3.4?

I was used to make costum boot cd's with the floppy drive and boot.img, 
that would boot knoppix from the harddisk.
-cheatcodes i entered in syslinux.cfg (knoppix fromhd=/dev/hda5 lang=nl 
etc) and made an costum boot cd , so to safely run an kiosk internet 
knoppix-
Now with the new version ( V3.4 ) it would be nice to do the same, make 
an costum only boot disk to boot knoppix from harddisk. And i would like 
to use K3B for it. Can this be done? And how?

thnx for the time.
