Wow, Damn Small Linux, what a throwback! That was how I was first ever able to run and interact with a Linux system back as a teen. I had no computer with Administrator access, but I found a zip file with DSL, a QUEMU.exe, and a .bat file which would run QUEMU and boot DSL, cause I couldn't figure out how. I never even got it to save to a persistent disk, I had to boot and re-do all the changes I'd figured out the prior time. What an amazingly educational little thing that was!
