Knoppix 7.4.2 will boot my flashdrive to the XOS but Knoppix 7.2 won't. And I worry the 7.4.2 bloat will make it an online target. (A major problem for me) I've tried just directly copying the 7.4.2 files and folders in various increments to 7.2, but still can't get the 7.2 flashdrive to boot the MacBook. Are there other files that need to be copied to 7.2 as well?

I'm so very grateful to have you folks helping here. Linux is very difficult for me. But Knoppix shows such promise that I'm compelled to try to learn it. Thank you for the help.
