Damn Small Linux or DSL is a free operating system for the x86 family of personal computers. It was designed to run graphical applications on older PC hardware—for example, machines with 486/early Pentium processors and very little memory. DSL is a Live CD with a size of 50 MB. What originally started as an experiment to see how much software could fit in 50 MB eventually became a full-fledged Linux distribution. It can be installed on storage media with small capacities, like bootable business cards, USB flash drives, various memory cards, and Zip drives.
