Help. Can not create LiveCD

I need to create my own LiveCD. It's based on LinuxFromScratch project (www.linuxfromscratch.org) - so, I compiled all tools from sources. Then I used some manuals "how to create livecd" but it doesn't work. I think that there are problems with kernel options.
Who can give me workable kernel configuration and link to livecd instructions where this kernel will work?
