I got a distribution from a computer magazine that was hastily packaged. It was a CDrom of a version of linux that runs under DOS with LOADLIN, had a filesystem called umsdos that s basically FAT (fat32?) with extra files for metadata. Unfortunately it seems the distribution didn't fit in the magazines' CDROM so they left out some directories, crucially /usr/man so most of the man pages were missing. It wasnt a linux magazine so there were absolutely no instructions.I didnt have internet access so it was impossible to figure out what to do. All the commands i could figure out were "cd" and "more" and "dir" (it was aliased to ls as i found out later). I somehow ended up finding some README files and similar and over time learned the basics. The rest is far less exciting to remember.
