Finally I managed to download a correct MiB iso and test it on my laptop.
It lacks drivers, unlike PCLinux and does not support old hardware and it hangs up on my desktop. It is heavy and lacks games.
It is very slow to boot and configure.
K3B is missing and I prefer its 2007 edition from which it has not improved due to commercial interests, I believe.
I hope I am wrong.
Knoppix 6.2 is thousands time better with many additions including virtual box and games.
