These two "SqueakOS" (http://swain.webframe.org/squeak/floppy/ and
http://www.ira.uka.de/~marcus/Squeak/SqueakOS/) are
actually two different projects, only with the same name...

My "SqueakOS" was a weekend project to build a "real" OS Kernel with
the help of OSKit. This uses a command-line Squeak (called "embedded
Squeak" which was based on Squeak 2.2 and originally done by Paul Fernhout)

OSKit is really nice, see http://www.cs.utah.edu/flux/oskit/ for more
information. They provide lots of little building blocks for a OS kernel
that can be put together as needed.
The SqueakOS Kernel does *not* have a Filesystem, Virtual Memory, Malloc, or
even a scheduler. It's more like a minimal bootloader for Squeak.

My first version of the bootable disk was based (like the "other" SqueakOS)
on Linux (actually a modified Debian Rescuedisc):
