I am trying to make possible remote Ubuntu boot. I have done one little thing, using this article  , but there is one roughness. I would like to boot Ubuntu Live CD on my client and work in this half-OS (using option Try Ubuntu) , while in this article one tells how to install Ubuntu Server. Definitely, we need to raise DHCP and TFTP. I have done it, but there is problem in /var/lib/tftpboot.   In my case it looks like:tree /var/lib/tftpboot//var/lib/tftpboot/ boot.txt debian  etch      i386          initrd.gz          linux pxelinux.0 pxelinux.cfg     defaultbut it is enough to install Ubuntu Server, while I need to run Ubuntu Live CD. Which files should I download and where to put them to make that possible?
PXE boot Live CD
ubuntu;pxe;tftp
