I loved it
The only time when an OS will be 100% bug and vulnerability free.
@@HaganeNoGijutsushi yeah
That would actually be a relief for it to do exactly what you expect 😀
99% of the time this doesn't happen
Yep sounds legit. About half of the demos I'm being shown.
This is the most complete video I've ever seen on building an OS. Thank you, sir! Don't stop, please
That’s what your mom said last night
He has stopped 😢

What a fantastic series of videos, they really tickle my tech curiousity. Everything I've been puzzled by is explained so well. Thank you for making these
loved this! back in 1985 i built an 8-bit z80 computer on breadboard (with a 1k static-ram chip) and had to program the RAM chip using 8 dip-switches (no assember) just in pure binary! it took hours to write code similar to this. after writing the binary code to RAM, i would then send a signal to the RES pin on the CPU to begin the instruction pointer (IP) at zero and begin execution of the code. all i had was an array of 8 led's as my output display. the code I wrote made the led's flash from left to right and vice versa, amazing days! this brings it all back! 😊 ps. i had to clock the z80 cpu at only 1 instruction per second (1hz) to be able to see the led lights move and the z80 assembly for that code was something like: l0: ld b,7 ld a,128 l1: out 0,a rra djnz l1 ld b,7 l2: rla out 0,a djnz l2 jp l0 (program size was just 21 bytes lol!)
Wow... that's quite fascinating.
That's incredible, love it
wow
real programmer
You did programming as von Neumann and the lord above us intended it, binary input, binary output, nothing else but switches and lights.
A truly enlightening experience for anyone seeking the raw essence of what programming is. Its flicking switches to convince lights to blink in the right pattern.
it's really rare to find quality videos in this topic.
Thank you sir for this excellent demo 🙏
just discovered this series , need to binge watch that now. This is so cool
i can say nothing more about this video other the "its perfect", the best OSDev tutorial i've seen yet. AMAZING
This is brilliant. All the other tutorials are messy file trees, horrible code, and hard to follow. This is perfect, easy to do, and the teacher is great. Keep going dude!
Absolutely adding this to the study list. I feel like this would probably be a great reference for delving further into CompSci
Do not waste your time on this crap
This is real computer science not website Makin
If anything UA-cam does good from time to time, is that he suggested this to me. I highly valuate this type of content, and as a developer and a lover of coding I have a big respect to this type of talented people, its way out of my league to do such things, even that like 25 years ago when started coding using basic 1, I had such ideas 😅, now you know the life took me, and have to pay the bills so I am a web dev, thankfully I am still in the coding family.
Big love and respect bro ❤
Excellent Tutorial. I love how you explain everything you are doing, this is a much better tutorial then any of the others I have seen!
This is gold , Thank you for the efforts
I can already see that this is going to be easy with this tutorial! PLEASE DON'T STOP, KEEP UP THE GOOD WORK!
this video would have saved me days of research if i knew it before i got into operating systems. Very consise and coherent, 10/10
This is a wonderful video, friend! Thank you for doing these videos, I'm loving them!
Nice video...
Looking forward to see how this progresses...
Made 4 yrs ago, I'll check your channel for other updates...
Thanks for the start. 👌
Amazing video, I managed to follow along, and I even learned some more asm.
I have always been kind annoyed with there being very few resources online for learning asm, so I barely know any, so nice to finally find a good resource.
the title is literally the content of the the video, you are amazing :) , dont stop never
You explained the most complicated subject like it's a piece of cake. Hats off to you man !!
This video deserves millions of likes ☘☘
That is one of the best tutorials of a complex subject I have ever watched. Kudos! 👏
I love this, please keep doing this kind of tutorial
That is the most complex "Hello, World" tutorial I've ever seen. Thank you for that
Thank you for making this tutorial. Now I learned a lot of things that will be useful for me
This is the perfect level of explanation for me, thanks!
this video is really good i never seen a complete video like this
Randomly youtube recommended me this video. I wont try to build an OS but I always wondered how it works, thank you
I'm literally into tears 😭 ... Overwhelmed by grateful emotions ☺️😌 ... Can't believe you put it for free on UA-cam! Thank You man, I can't thank you enough... !❣️🙏🏾🙏🏾
You really sound like a bot rn
@@thewaterwave222 That's what she said bro 😭😅
ok bot
@@samarthtandale9121 thats what the [[BIG SHOT]] said
damn thats one useless bot
YOU ARE A LEGEND ONLY THIS ONE WORKED PERFECTLY!!!!! THANK YOU!!!!
This is truly fascinating tutorial, congratulation
Absolutely amazing video! Thank you loads!
Cool Thank you so much you are the best person who has explained assembly:)
It's really good to see people having fun with Assembly like this. I know we live in the age of languages like Python and Assembly can be a frustrating, painfully slow, counterintuitive language at times that tests your patience and confidence when things don't work, but I think everyone who enjoys programming should learn to work with at least one instruction set and experiment with it like this. Just mess around, play with it. At the end of the day we're just kids playing with really complicated toys and making them do tricks when we program anyway.
Hi! I thought this was great! I hope you'll make more some day. All the best from a fellow programmer(mostly c# :))!
this probably needed so much work thanks for the effort!
That was amazing man!
This made me actually understand kind of how an is works and I already have an idea of how a kernel works too
The best video for begginers about this topic!! Excellent!
Thank you VERY much for this series. I have mentioned wanting to get into OS design many times on other programming groups and been laughed at and mocked because why am I not in the kitchen making dinner lol. I've been writing in C and recently learning assembly, so now I will go back to them with an OS (after a few more years of this).
have you completed your os?
@@spytonic4171 Not even close. Life got in the way, but I am picking it back up now.
Thank you so much for these videos!!
Best for creating os. Please do more videos!
Greatest stuff that i seen ever, man, continue plea
Hey Nanobyte, you are one of the best and most underrated OSDev channels on UA-cam!
You even inspired me to create a OSDev channel. Just need to find a easy to use video editor and it's done!
BTW I am a Legacy BIOS Windows 10 user (and I will change to Linux in 2025)
Why 2025?
@@astric32dll thats the end of support for windows 10
@@antonGanG not anymore now it is end of 2023
Dual boot to get more familiar with Linux
Thanks a lot sir, amazing explaination
waiting for the next video !!!!
This channel is amazing. Keep the great work, mate!
This is awesome. I watch it, and get like 50% of it. Then I search for while and I understand it more. But it was till I start building my own floppy disk OS bootloader to understand it on 100% Thank you very much for this. It made me eager to learn more!
I've been searching for ages to find something like this
just amazing
Thanks so much for these videos!
I really enjoy technical low-level programming projects that present the necessary theory and definitions. I hope to see you building a compiler for a toy language from scratch one day. Or a webbrowser :)
truly brilliant !
Great video, thank you. Subscribed!
Terry Davis would be proud. Now everyone can homebrew their own temple OS.
Thanks! That made good sense.
Thank you for this!
This is great, thanks for teaching us. I thought it would have been funny if you used nano to build your os
Wow amazing tutorials, I have previously written assembly bootloaders and a basic operating system more like a shell tbh and no one really explained about the syntax of certain assembly things like $ and $$, I knew I could jump to $ for a hlt but never what the $ - $$ did in the times loop and now I do!
FLIP db "blub blub"
fliplen = (FLIP - $)
$ is the current location in memory.
This is so cool!
Thats's fck'n awesome, i'm writting a compiler and the video is sooooo usefull
6:50 fire voice crack 🔥🔥
Very underrated
The best Tutorial guy!
Well structure. Thank you very much
A stack is LIFO (last-in-first-out), not FIFO. The FIFO equivalent is called a queue.
Lov u
Yes I came down here to make this exact comment.
at least the animations were right
thank you, I was thinking the same thing !
Great video, thank you very much :)
Great Video
wow i just found this its awesome .
brooooo really thanksssss keep going
I like this guy, he hesitates and still gets it wrong (13:29), but all in all good tutorial
Recording videos was really stressful, especially when I started making videos. Today, I have a better workflow which helps a bit, but mistakes still happen.
cool videos thank you for the information
The best youtube channel ❤❤
Finally, someone who appreciates micro. I absolutely love it.
It's a nice editor, but I don't use it as much nowadays, VSCode is just better. When I need a simple editor on linux, I always fallback to vim because it's always there preinstalled, and I've learned a few basic commands.
@@nanobyte-dev Totally understandable. I never did get productive with vim, unfortunately. But with micro, I was actually able to learn a lot of shortcuts, so I'm pretty productive. I go back and forth between that and VS Code because it genuinely is amazing.
@@trebabcock I Agree, My Chromebook Sucks At Running VS code, And Micro Is Much Better, Yes, Understandable.
Quality overview
very informative
This is GOLD
its pure information, tnx u
great job bellissimo molto interessante
Badass dude really badass, this is Bill Gates level of making an OS. I will be looking forward to this. I am an Windows and Linux user so i play around with virtual machines so this should come out simple for me. Can't wait to make my own OS
Rollercoaster Tycoon 2 was written entirely in Assembler. I cant even imagine how much work the guy put in this to make it happen.
Thank You very much
I love you man! Greetings from Serbia.
just amazing!!!! in 17:11 u mentioned stack as fifo but it should be like LIFO right?
Yes, you are correct
just noticed the same :-)
Awesome
Very easy to follow instructions and explanations. One factual error: a stack is a LIFO not a FIFO.
Very good videos dude, congrats! The stack is LIFO Last In First Out not FIFO 😂
I actually followed this tutorial on android😂
Excellent tutorial 👍❤
There is probably absolutely no way you are making an OS on Android unless probably if you got an extremely high-end Phone.

Thanks!

Wow, thank you very much, you are very kind.
When using VMware, it's actually faster to use PXE than going all the way to using floppy images, you just make an empty VM with a network card and you setup your Ubuntu as a BootP server + NFS server (in the old Sun style). From there, just reboot the VM, everything else is automatic, you can jump to 64-bit mode much earlier, even before you display anything.
By the way, ISO images are also easy to generate and somewhat more "portable" than floppy images.
i couldnt get qemu installed on kali purple so i used Virtualbox else everything was GREAT!
Wow, everything in 23 minutes, it took me several days, weeks, to find info and figure out how to create a bootloader exactly like this 17 years ago in the 2000s internet
WOW!
This tutorials are really awesome ! i just wanted to ask, is knowledge of Data structures and Algorithms are necessary for building an OS
There are some areas where they are useful, like memory management, or process scheduling. Also keep in mind that when you are building an OS you don't have the standard libraries, and you may need to implement some of these yourself. The good part is that there are a lot of resources available online, so you can learn them as you go.
@@nanobyte-dev thank you for your reply, you are doing great job for the community thank you so much!!
This video is gold for people who want to learn something new everyday, but unfortunately we live in a world where a tiktoker easily gets millions of followers but a youtuber hardly gets any recognition.
"so far our operating system does nothing and does it perfectly" wow incredible
I was sent here by a link in a comment written by someone named Tomi Ivaswort. I have no idea who you are, but I just want to say, thanks for that link.
Good video Sir ! Btw do you recommend any books about things I should learn to better understand your tutorials ?
You can start with reading from the OSDev wiki, or following some text tutorials which will help you get started. The brokenthorn tutorial was my favorite. If you want to go into more depth and more theory, there are 2 great books that always get recommended, Modern Operating Systems by Andrew Tannenbaum and Operating System Concepts by Silberschatz. These are really good for theory, but maybe a bit difficult in practice. I know there is a good one about Minix, but haven't read it. I haven't really read any book related to operating systems (just partially read Tanenbaum's), but I would like to do that because I'm sure there are many things I could learn. I'm hoping to come back to this question in the future and come up with a better answer.
@@nanobyte-dev thanks ! I will take a look at these .
Do you know how you could load this onto a usb and have it working on bare metal? I tried on linux using dd command, it does find boot sector but no string prints
