w84deathon An Embedded Linux on a Single Floppy

Confirming.

Also the goal was to run LATEST kernel with no changes - just config. With other compression algorithms it was impossible to fit everything into a floppy. And I really wanted to have nano and some space to save few files. Without this it would be totally not usable OS.

exactly that: too complicated.

also I got 486 DX2/66 as my first PC so I set that as a goal. Then checked how lower can I go. Also I only have 486 DX4 now to test on real hardware.

Isn't it still alive in automobile/infodesks?

QNX is to this day the biggest "floppy" thing I ever saw.

I would love to have a modern recreation of it.

Thanks again for being featured here!

Nice to read all of those comments. The project goal is more to learn how to make your own Linux distribution than to fit as much as possible on a floppy. It is fun to have a fully working OS at the end of this learning experience. Floppies are easy to use and just cool :)

There are a lot of better suited distributions for size and memory usage. What makes FLOPPINUX stand out is the complete tutorial to follow and then make your own changes on top of it. Learn and have fun!

I did not realize but I made an equivalent of a OS for writer deck that fits on a single floppy!

It boots latest Linux, spawns console and have Vi for editing persisted files on that boot floppy. Runs on 486 CPU.

I've updated the code to stable version moments ago!

w84deathon Ask HN: Comment here about whatever you're passionate about at the moment

I got obsessed with Stable Diffusion. I get past the honeymoon period generating everything I could imagine, and now I'm trying to actually incorporate it in my daily work. Furthermore, I'm sharing my experiments here https://bits-next.p1x.in/generating-perfect-grass-textures.h...

Another new and exciting thing for me is the Gemini protocol. The simple, low-tech internet. I started porting all my texts/websites to my own capsule at gemini://floppy.p1x.in (server from real 3.5" floppy!)

With sample application and KIOSK mode.

Did you try qemu-system-x86_64 instead?

w84deathon Floppinux – An Embedded Linux on a Single Floppy

It could be 2 things:

- you compiled some parts in 64 bits and try to run the QEMU 32 bit system. Try qemu-system-x86_64

- you do not enabled starting #! scripts in the kernel

w84deathon Floppinux – An Embedded Linux on a Single Floppy

Nice catch! Thanks.

w84deathon Floppinux – An Embedded Linux on a Single Floppy

I got similar problems when I missmach 32bit and 64bit code. First try to run in qemu 64 bit system.

I ended up building the whole system on a 32bit old laptop and just don't care about the problems with installing missing 32bit libs on my 64bit system.

w84deathon Floppinux – An Embedded Linux on a Single Floppy

I can. Why not. Updated the post. Here's the link: https://krzysztofjankowski.com/floppinux/downloads/0.2.0/

w84deathon Floppinux – An Embedded Linux on a Single Floppy

Thanks! I changed the file name in the meantime and forgot about the link. Fixed!

w84deathon Floppinux – An Embedded Linux on a Single Floppy

Thanks! When I saw how clean and easy it can be in just a few steps I needed to share that knowledge!

For me it's the best way to learn Linux.

w84deathon Floppinux – An Embedded Linux on a Single Floppy

Barely. If you want to just run some compiled C app then you don't need as much tools. You can even skip the BusyBox part and instead of shell running your application only.

But I don't think it is what you want. For sane set of tools it was a little bit over 1MB. Mine is bigger as I still need more tools for fixing/experimenting on live system (I'm using shell scripts for my application). In the end I will be removing more and more tools.

w84deathon Floppinux – An Embedded Linux on a Single Floppy

I should see floppy drive as /dev/fd0. Just now as I double check everything I found out that external drives (USB) are shown as /dev/sd*. sdb in my computer.

I updated the post with that info.

Thanks!

w84deathon Floppinux – An Embedded Linux on a Single Floppy

I was thinking of publishing those. Not a problem. I will update the post in a moment.

EDiT: done :)

w84deathon Floppinux – An Embedded Linux on a Single Floppy

It is read only and will run one particular application in a kind of KIOSK mode. I'm using floppy just for fun.

w84deathon Floppinux – An Embedded Linux on a Single Floppy

Thanks!

w84deathon Floppinux – An Embedded Linux on a Single Floppy

Yeah, I just wanted to learn Linux. It worked as I learned a lot doing this project :)

w84deathon Floppinux – An Embedded Linux on a Single Floppy

This blow my mind back then.It is still super impressive.

I have my base in Poland. And those times I'm less of a nomad due to many things including some virus in the air.

I found this trick to make vimeo videos "seamless" just as gifs back in the days. It's surprisingly not distracting yet super vivid :)
