antiX Linux

A Debian-based live-CD system perfect for burning it on a USB drive and using it to access a non-working PC. There are versions for 32 and 64bit (no ARM) and four options based on the number of included packages: core, net (both without a desktop environment), base and full.

Minimum required specs (for “antiX-base”):

  • Pentium II
  • 192MB RAM
  • 3GB hard disk storage

32bit version uses a non-PAE kernel, that’s useful for using on very old computers. There are several window managers included (Menu -> Desktops -> Other Desktops, try one of the “minimal” versions to reduce RAM usage to the minimum).
