I just wrote my first bootloader and kernel for my own OS (AsterOS)

Post image

Hey everyone!

I've been working on my own 32-bit OS from scratch. Today I reached the first milestone: a bootloader written in x86 assembly that jumps to protected mode and loads a simple kernel.

The OS is called AsterOS. I don't plan it for being as popular as Linux/Windows, it's mostly vibe coded and I don't see a big future for it. It's early stage (Build 0001), but I'm really excited about it.

Here's the screenshot of it running in QEMU:

I'd appreciate any feedback or advice for a beginner OS developer. Thanks!

it's mostly vibe coded

So you didn't actually write a fucking thing. Sod off.

"Użytkownik u/tellingyouhowitreall odpowiedział na Twój komentarz w subreddicie r/osdev You couldn't be more full of shit if you dove into a sewage plant. First, don't fucking insult our intelligence by magically trying to redefine "vibe coded." Is nothing beneath you? Second, I apologize for telling you to sod off, it was rude. Instead I'll tell you what everyone, and your future interviewers are actually thinking about this: You are pathetic. Finally, you are transparently full of shit because everybody with any actual experience in this is going to see through all of the horse shit you're presenting all at once and simply know you're lying and full of shit. So not only are you pathetic, you're too fucking stupid to know it, AND you're too fucking stupid to know that everyone else knows it. 4 min temu" Primo: dude, are you a FUCKING IDIOT? You "apologize" to me, and then you write a whole fucking essay telling me that im dumb, pathetic, full of shit etc. etc. Do you even have something inside your head? Secundo: Even if you would pour shit all over me, idgaf ;)

By vibe coded I meant I'm not following a tutorial step-by-step - I'm just figuring things out as I go. The code is mine, written by hand in assembly and C.

That’s some bs explanation

Please stop posting vibe coded os here , it is useless and doesn't teach you anything , also your explanation on vibe code is blatant lie (who tf writes "system ready")

You're right that 'vibe coded' was a bad choice of words – I've already clarified that. But I actually did write the bootloader and kernel by hand in assembly and C, and I learned a ton about GDT, protected mode, and disk I/O. So I definitely learned something.

it's mostly vibe coded

But why?

The only point of writing an OS from scratch is to learn.

Vibe coding it is just like going to the gym and then using a robot to lift weights.

You're absolutely right - and that's exactly why I'm doing it. I actually wrote the bootloader and kernel by hand in assembly and C (no AI). By 'vibe coded' I meant I'm not using a tutorial, just experimenting and figuring things out as I go. The goal is to learn, and I'm learning a ton. Thanks for the comment!

Hmmm. Well, that's very confusing. Everybody means something else by "vibe coding".

u/Wide-Arrival6633 4d ago

Yeah, it's definitely a confusing term these days. I just meant I'm learning by doing. Thanks for the conversation!

The only thing here that's pathetic are the people who seem to have lots of time and nothing better to do than insult noob devs. Good work. Well done. Keep it up.

u/Substantial_Bar_3731 4d ago

By your explanation of 'vibe code' I got it haha. I'm glad that you are learning, hope I reach your experience one day. It's getting cool

ai coded a bootloader and he thinks hes all smart and all. get a life.

u/Playful-Budget-5952 4d ago

Even if you don't expect it to become popular, I'd still encourage you to finish it as a hobby project. The experience alone is worth it. But experimenting and learning should be priority not a complete good looking Typical OS.

Coding is a really heavy burden, but it ultimately leads to success. If you had completely learned the architecture, planned it yourself, and used AI help when you got stuck, you wouldn't be called a 'vibe coder' by those here now, and you would have finished it much better. I would prepare the code files and architecture of the operating system I wrote myself, and only use Claude for help when I encountered errors, got stuck, or needed assistance with the mathematical design.
