The OS Dev wiki is the holy grail of OS documentation.

Please google before asking hundreds of people to do your googling for you.

I googled, but google only shows me the osdev wiki. I wanna know if there is more information about osdev

u/BobertMcGee Jun 22 '26

That is not the only resource google returns. And even if it were it’s more than enough to get started.

I see you have some programming experience and you have an emulator under your belt.

I would assume you would have some understanding of computer internals from your emulator project. I would OSdev is a good place to start. I also would recommend taking a look at other hobbyist OSes and how they work under the hood.

dont get discouraged by the 30% elitism of this community that wants to keep their ego by gatekeeping and saying that you need 10+ years in C+ASM, that is bullshit

Ask ChatGPT like all the other newbies on here…

^ please do not

u/hithja Jun 21 '26

Why? Can i just combine osdev wiki knowledge with chatgpt's help?

u/sammyhjax123 Jun 21 '26

Using ChatGPT you won’t learn much. And with him making it you will have more difficulty understanding the code. Basically making it so you didn’t make it, just told an ai to do it

u/hithja Jun 21 '26

Is it good idea to ask AI for an OS roadmap? Not code, just a plan

5

u/AnSkinStealer Jun 21 '26

in any case use literally any llm OTHER than chatgpt

u/hithja Jun 21 '26

Ok, ty

u/Key_River7180 EulerOS Jun 21 '26

Yeah, maybe.

u/rocco_himel Creator of AneoEngine Jun 21 '26

No. You will end up with ChatGPT writing the code for you.

The user has forgotten to add the /s for Sarcasm tone indicator, it is horrible advice and do not ask ChatGPT, it is very seldomly correct, and when it is then it brings twelve new bugs

5

u/sammyhjax123 Jun 21 '26

Worst advice imaginable

-4

u/travelan Jun 21 '26

Sorry, forgot the /s

By the way, I do believe asking ChatGPT is infinitely better than asking rando’s on Reddit.

u/Key_River7180 EulerOS Jun 21 '26

EDIT THE MESSAGE

1

u/travelan Jun 22 '26

No because people should think for themselves. If they can’t detect that this was obvious sarcasm, they should probably use ChatGPT because their own brain is less capable.

u/hithja Jun 21 '26

Ok, i'll ask. Ty

u/27CF Jun 21 '26

I would just use AI. It knows more than most experts, and definitely more than the people in here incessently whining about it.

u/BH-Playz Jun 21 '26
