You’re OG. My first was some unknown distro that installed in DOS on my Win95 machine and dual booted that way. Totally confused me. Second was Red Hat 6.0 in 1999. That one, I was a little more successful with.
I did try that weird linux on fat32 distribution but like you I completely forgot its name. I remember that I installed it because I wanted to run bitchx and be able to send ping of death!
