Slax

Slax is a Linux Live CD based on the Slackware distro. It does not need to be installed on a computer system's hard drive, as it boots and runs from removable media (either a CD or a USB drive). There is also an option to run SLAX from RAM. SLAX Standard and KillBill editions use KDE as their desktop environment, while Popcorn uses XFCE. Fluxbox is an option in all versions except Frodo which is for users with a low amount of RAM.
