Chaos and older version of Quantian, just like clusterKnoppix itself, all
_defaulted to loading the openMosix-ready 2.4 kernel_.

Newer versions of Quantian default to the 2.6 kernel, so you have to
explicitly load the 2.4 kernel.  If and when you do that, it should
plug-and-play with Chaos, clusterKnoppix and other systems running the same
old 2.4 kernel with openMosix.

openMosix for 2.6 has been "ready any time now" for the last few years, but
there is still no real release.

Could you try again and make sure you get the 2.4 kernel from the boot
prompt? 

Good luck,  Dirk
