Latest FLOPPINUX Workshop was just released!
Make your own Linux distribution on a single 💾 floppy disk in less than one hour!
=> https://krzysztofjankowski.com/floppinux/
Available as HTML, Markdown, PDF, and EPub.
New additions in latest revision: updated kernel and tools, persistent storage.
#Linux #BareMetal #OS #Homebrew #Floppy #1440KB #Hacking #Embedded
I make the FLOPPINUX even smaller!
264KiB left on the floppy for personal files and scripts.
Draft of the new tutorial is here: https://krzysztofjankowski.com/floppinux/floppinux-2025.html
FLOPPINUX 0.3.0 will have persistent storage on the boot floppy!
There is 196KB space left for files :)
I've restored and updated my blog posts into a dedicated page about FLOPPINUX - An Embedded 🐧Linux on a Single 💾Floppy

I'm now revisiting this and want to make an refresh update for 2025. Stay tuned.
For everyone wanting to test out OS/1337 there's good news:
You can just clone the #git repo or pull it as #zip:
https://github.com/OS-1337/OS1337
and then just run ./scripts/build.sh
and within a few mins it'll spit out a bootable #1440kB image in /build/0.CORE/ to put on a 3,5" FDD or run in a VM [may it be #QEMU or #VirtualBox]...
Thanks to @SweetAIBelle for the generous contributions!

I do want to get rid of #syslinux because it's like 200kB of #Perl that make it harder to make OS/1337 fit a #1440kB FDD.

Luckily @landley already pointed out the solution to me:
https://github.com/OS-1337/OS1337/issues/10#issuecomment-1868276691
So all I need is get rid of my headaches and some time to make the #MinimalLinuxBootloader go brr!

As @landley pointed out, syslinux has perl as dependency and as per observation is consuming quite a lot of space. So far, thanks to @sweetaibelle the following options are on the table: mlb - Mini...
So if anyone with some #ISA-based #3Com / #AMD / #Intel / #VIA #NIC's wants to test OS/1337, you can find the current #1440kB 3,5" FDD Image here:

#Feedback is highly desired and can be left here:

Thanks again to @SweetAIBelle and @landley for their contributions and feedback...
I really did squash a lot of issues in OS/1337:
https://github.com/orgs/OS-1337/projects/1
Good news: Network Support is in it.
Status: Still within #1440kB size for the #Core Edition.
Bad News: PCI(e) stack had to be yeeted in order to fit, so no #Networking in #VirtualBox
I'll now have to get my workflow to follow the pipeline that @SweetAIBelle has been builing...
#OS1337 #linux #EmbeddedLinux #Development #Kernel #Embedded #minimalist #Desktop #toybox
@landley @whitekiba @OS1337 sry.
My quest is to see if something like #tomsrtbt can be done with modern versions of #Linux & #toybox.
I know #mkroot is meant to show a full #musl + toybox / linux system for each supported architecture without sacrificing features and drivers along the way whilst retaining readability and reproduceability.
So OFC it can't fit on #1440kB...
But what can fit is a shimmed-down system able to load additional tools and/or flash/write a bigger system onto disk.
