Looks a lot like mandrake linux and runs entirely from CD/ram. Run it in VMWare or reboot from cd. Any thing you screw up will be corrected with the next reboot. An excellent way to learn about linux without the instal hassles.
http://www.knopper.net/knoppix/index-old-en.htmlWhat is KNOPPIX®?
KNOPPIX is a bootable CD with a collection of GNU/Linux software, automatic hardware detection, and support for many graphics cards, sound cards, SCSI and USB devices and other peripherals. KNOPPIX can be used as a Linux demo, educational CD, rescue system, or adapted and used as a platform for commercial software product demos. It is not necessary to install anything on a hard disk. Due to on-the-fly decompression, the CD can have up to 2 GB of executable software installed on it.
