slax:

  This is a live (bootable) CD with Linux OS based on Slackware distribution,
  created by using linux-live scripts. See http://www.slax.org
  SLAX is the new name for unofficial Slackware Live CD (not distributed by Slackware.com)

how to use SLAX:

  Burn the ISO by using "Burn CD ISO image" menu in your burning software.
  Then insert SLAX CD to your CDROM drive and reboot your computer.
  Make sure that cdrom booting is enabled in your bios.
  Voila, you are running Linux now! ;)

  You can also run it from DOS (in the case your bios cannot boot from CD),
  just start X:\dos\linux.bat from the DOS prompt.
