KNOPPIX 6.7.1 is an updated version of the popular Debian-based live CD and DVD featuring the LXDE desktop. Despite the minor version bump, this release contains a rather large number of updates. It has been updated from Debian 'Squeeze' with the usual picks from Debian 'testing' and 'unstable'; it uses Linux kernel 3.0.4 and X.Org Server 1.11; experimental free nouveau graphics modules supporting NVIDIA cards; OpenOffice.org replaced with LibreOffice 3.4.3; Chromium 13.0.782.220 and Firefox 6.0.2 web browsers; optional 64-bit kernel via 'knoppix64' boot option, supporting systems with more than 4 GB of RAM and chroot to 64-bit installations for system rescue tasks; new boot option for mounting the KNOPPIX compressed file system from a stored ISO file; boot option 'grub' for starting a bootloader shell in system rescue tasks.
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.
