If I remember correctly, QNX 4 demo was the first graphical OS that I've seen booting and running from a floppy. That was somewhere in late 90s.

As impressive as it was at the time (and still is), a floppy is writable.

Booting from read only media and having a fully functioning OS was completely groundbreaking. Especially when you consider how much hardware was supported without configuration.

As I recall, it worked exactly like a modern live CD, with no state saved to the disk.
