I have Knoppix installed, hdd, on a HP Pavilion ze5600. 2.6ghz, 768 RAM, 30GB HD. Everything is working, CDROM, network (obviously). I previously installed an older version, I forget which one off hand, it was sometime last year in the spring, and had no issues either. Actually, I lied, the wireless card was fubared. Anyways, just thought I would post and let people know that it can work.
