Accelerated-KNOPPIX and the Acceleration Kit for cloop Live CD was released under GPL (GNU Public Licence).
The development of Acclerated-KNOPPIX is developed by Alpha Systems Inc. and adopted as a "Project of Infrastructure Building for OpenSource-Software 2005" by Information-Technology Promotion Agency, Japan.
We evolve live CD to not only trial, but the base of open source software.
"A LiveCD is an operating system stored on a bootable CD-ROM that can be executed from it, without installation into a hard drive. Live CDs have a reputation for supporting advanced auto-configuration and plug-and-play functionality. This is necessary so as to avoid requiring the user to configure the system each time it boots, and to make them easily usable by those who are new to the operating system. " (Wikipedia.com)
It is not only KNOPPIX to benefit from the development of boot time improvement, but also other Live CDs which use cloop file system.
A cloop profiler is developed in order to grasp the access situation of CD.
Although various files are referred to in Live CD in the case of a system startup, since each position of media is dotted with the file, a lot of seeking will generate it at the time of reading. If the seek time of this CD is lost, it will be said that data can be transmitted at a stretch from CD. Then, the seek time of a pickup is reduced by rearranging the file read at the time of starting on a block level.
Live CD performs automatic recognition of the peripheral equipment of PC at the boot sequence.
Although the cache of the file required for starting of a desktop are predicted and carried out in the meantime, if there are few memories which can be used for cache, starting will become slow conversely. By this development, memory capacity is examining making it an effect show up at least because the predicted data carries out the cache of the compression image of cloop as it is.
!ATTENTION! Thank you for your interest in Acclerated KNOPPIX. Due to heavy demand, it is now very hard to download iso image. Please try again later.
English version KNOPPIX can be used by inputting the following boot option. boot:knoppix lang=us
