Knoppix is a live CD (700M) or live DVD (3.2G) based on Debian GNU/Linux, with lots of ready-to-run programs (web browser, office suite, a few games, and more), using KDE as desktop environment. It can be booted directly from CD, without any installation needed. You can download it from knoppix.org.
As Knoppix runs completely from CD/DVD, you don't need to setup a hard disk. You just need to set up the location of the downloaded ISO image in your bochsrc, and make Bochs boot from it. Because Knoppix contains a graphical user interface, and has no other storage space but the emulated RAM, it needs at least 128MB of it, see megs option. Furthermore, you need to enable VBE support in Bochs (see Section 8.16).
There is nothing more to do! Just start Bochs and wait for Knoppix to load...
