I downloaded this code and burned it to a DVD, and all the md5s agree, but I can't get that DVD to boot on either a 64bit system or on a 32bit system. The bootloader does not recognize the cheatcodes "knoppix64" or "knoppix32", nor will it boot with no cheatcode at all. I have used Knoppix distros for ten years now but have never encountered a problem such as this. Is anyone else having such a problem?
