Knoppix contains scripts (which you can access from the Knoppix menu) for saving your configuration settings (e.g. X setup, passwords, etc. -- the config files you'd find in /etc) and for saving a "persistent home" (i.e. the /home/knoppix directory, which would include your Firefox browser).

The easiest way to do that, if all you've got is an NTFS partition, is to use a USB key/thumbdrive. Now the problem with that is, if you're using the 2.6.9 kernel, a new USB filesystem driver's been implemented, but the Knoppix scripts haven't been rewritten to take the new filesystem into account. Meaning, your USB key/thumbdrive won't show up as a place to save your persistent home or configuration to.

(Using kernel 2.4, your USB key = /dev/sda1; using kernel 2.6.9, your USB key = /dev/uba1.)

The good news is, you can run the 2.4 kernel, save your configs and your persistent home on your USB key/thumbdrive, and then use them with the 2.6.9 kernel with no problem.

You can also save your configuration to a floppy (it's very small).

Anyway. Choose "Knoppix menu > Configure > Create a persistent KNOPPIX home directory" or "Knoppix menu > Configure > Save KNOPPIX configuration" to do either one. Do not try to save them on an NTFS partition.

As far as accessing a floppy goes: Put the floppy in the drive and click on the floppy icon on the desktop. Knoppix has something called an automounter that will, er, automatically mount the floppy if there's one in the drive. It'll show up as /mnt/floppy in Konqueror (the file browser).
