He's talking about the LiveCD - he hasn't said anything about an installation, and this: "Burned the ISO... restarted comp... hit enter at boot screen." looks very much like he's using the LiveCD.
Either the iso was corrupted, the disc wasn't burned properly, or it's a hardware issue. You can check if the disc is the problem with "knoppix testcd" at the "boot:" prompt. If there's no error in the CD, check out the cheatcodes, which (at least on my 4.0 DVD version) are in D:\KNOPPIX\knoppix-cheatcodes.txt
