'Damn Small Linux', and 'G-Zapper'

Damn Small Linux

Damn Small Linux is small enough and smart enough to do the following things: Boot from a CD as a live Linux distribution no matter what OS you're running, boot from a USB pen drive, boot from within a host operating system (that's right, it can run *inside* Windows), run very nicely from an IDE Compact Flash drive via a method we call "frugal install," transform into a Debian OS with a traditional hard drive install, run light enough to power a 486DX with 16MB of Ram, run fully in RAM with as little as 128MB (you will be amazed at how fast your computer can be!), Modularly grow -- DSL is highly extendable without the need to customize.
