I just put the Fedora KDE Live CD on a USB stick, and succeeded in booting 2 machines with it, one a very small VIA EPIA machine. Both worked fine I followed the instructions at <http://fedoraproject.org/wiki/FedoraLiveCD/USBHowTo> but found one part didn't work for me. You are advised to write the MBR with cat /usr/lib/syslinux/mbr.bin > /dev/sdb This didn't work, and I did what I would have done anyway: dd if=/usr/lib/syslinux/mbr.bin of=/dev/sdb The other point is that rather surprisingly the instructions did not point to the ISO required. Finally, I found the USB stick was (perhaps not surprisingly) mounted read-only, so one could not eg add a user; or rather, one could, but it was not there on re-booting.
