We are sorry but the Voltalinux linux distribution is discontinued.
As old reference to the project we still store this page: http://voltalinux.sicurezzarete.com/
If you would like to experiment with something similar to Voltalinux but updated you could follow those 4 simple steps:
1) download the minimal installation Slackware iso image (about 40 MB) from Alien:
2) install it
3) download the terrific piece of software pgksrc from NetBSD project:
4) bootstrap it and continue with the compilation of the packages you like…
Good luck !
