1. I never got NetZero to work with Linux. In fact, when I checked, their web page specifically said that it did not support linux. Problem with NetZero, Juno, AOL and the other mainstream dialups is that they have their own proprietary shells for running, and if they don't write them for Linux, you're stuck.

2. Easiest thing would be to boot from an ISO image using the bootfrom= cheatcode. If you downloaded knoppix for burning to a CD-R, you may still have the ISO file on your HD. If so, integrate the bootfrom= cheatcode into your startup at the boot prompt. E.g., if your ISO is at hda2, and you're installing the 2.6 kernel, restart with CD and type 'knoppix26 bootfrom=/dev/hda2/k*.iso" at the boot prompt. Better yet, save the compressed image to a non-NTFS partition, and use the "tohd" and "fromhd" cheatcodes. If you do either, you can remove the Knoppix CD after booting, and use your CD drive for whatever you wish. I did a step by step in the to/fromhd cheatcodes in a recent thread, which may help. You may also want to set up a persistent home and save configuration, so that what you install will stay there. http://www.knoppix.net/forum/viewtopic.php?t=11856
