How to Install Puppy Linux On a USB Flash Drive
Puppy Linux is a family of distributions that provide a simple way to use Linux on lower-end machines. Unlike regular distros, Puppy Linux uses popular versions of existing distributions and it modifies them to run with lower system requirements. This allows you to install this distribution on just about any system and storage medium possible. For example, you can install and boot a working copy of the latest version of Puppy Linux on a 512MB flash drive. This article shows you how you can do just that.
