I've written a document about how to build a bootable Squeaky OS. 
http://swikis.ddo.jp/umejava/27

Squeakware is based on SLAX - a compact, customizable Linux 
distribution.

You can burn Squeakware to a mini CD, or USB memory stick. You can 
also customize Squeakware by a few simple steps.

Enjoy! Always with Squeak!
