d a m n-Small Linux
DSL is a very versatile 50MB mini desktop oriented Linux distribution.
d a m n Small is small enough and smart enough to do the following things:
Boot from a business card CD as a live linux distribution (LiveCD)
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
DSL has a nearly complete desktop, and many command line tools. All applications are chosen with the best balance of functionality, size and speed. d a m nSmall also has the ability to act as an SSH/FTP/HTTPD server right off of a live CD. In our quest to save space and have a fully functional desktop we've made many GUI administration tools which are fast yet still easy to use. What does DSL have?
