Puppy Linux
Tiny, runs from RAM, and boots almost anywhere.
What is Puppy Linux?
Puppy Linux is a family of very small distributions assembled with the woof-CE build system from Ubuntu, Debian, or Slackware packages. It loads into memory at boot, which makes it quick even from a USB stick, and can save sessions to a file. It is ideal for rescue work and ancient hardware rather than a modern full-time desktop.

Puppy Linux system requirements
For a comfortable desktop with a modern web browser, plan for about 1 GB of RAM, and less is workable with a light desktop. Puppy Linux is available for x86_64, i686, including 32-bit PCs. Leave at least 25 GB of storage for the system and applications. These figures are editorial guidance; check the official documentation for minimums.
Try Puppy Linux before you install
Write the image to a USB stick and boot it as a live session to test Wi-Fi, graphics, sound, and suspend on your own computer. A browser trial on DistroSea shows the desktop, but cannot verify your hardware.
