Just to clarify, testcd is not another kernel. It is the same bootup process as the default, except that Knoppix runs the testcd script during boot up.

Assuming that the md5sum checks out, have a look at the Cheatcodes:Tips&Tricks section. Which of the two boot commands did you try, and how far in the boot process you were able to get?

BTW, what Knoppix version are you using?
