That’s impressive…but what device in 2021 needs to boot from a floppy? Today’s embedded devices are typically smaller than a floppy drive, and find something like microSD to be more appropriate, which also means having an absurd amount of storage available.
I’m gonna guess “something old”
Because it’s fun.
just pandering to a specific crowd being nostalgic with older things.
This is how my first Linux router in the late 1990s worked-ish. There was a Linux distribution called fli4l.
Yeah, but can it run Doom?
Doom needed four floppies. Doom 2 took 5.
Perhaps it could be loaded into memory from a DAT cassette.
Most of the Doom data is game assets and levels though, I think? You might be able to squeeze the game engine and a small custom level in 400k.
Yes it is. But the engine itself is about 700k. The smallest engine (earliest releases) were a little over 500k. You could probably build a smaller one with modern techniques and a focus on size though.
Good news, ADoom for Amiga is only 428k! Bad news, Amigas only have double density FDDs so you only have 452k for the rest of the distro.
muLinux used to be something like this, but some ~25 years ago.
