Coyote Linux, maybe? I used it at home in the beginning of the 2000s.

There's a famous single floppy router distribution: https://en.wikipedia.org/wiki/Linux_Router_Project

LGR has a video on a PC-based appliance (a wireless access point) where the "firmware" source was a walled-off 3.5" drive with a floppy inside. That one ran DR-DOS however: https://youtu.be/DOkapxbW93g

I believe that was it but Coyote Linux sounds familiar too. I think it perhaps used that distribution.
