Making an OS (x86) Chapter 1 - CPU, Assembly, Booting

День тому

In this video you will (hopefully) learn the basis of what the CPU is, what Assembly is like and even use some Assembly code to create a functioning boot sector.
Corrections:
- It's not SUM ax, 5 but ADD ax, 5
- Times is not an "instruction", it only repeats an "action" n times in the binary file.

To install nasm and qemu on linux (debian) run the following commands:
sudo apt update
sudo apt install nasm
sudo apt-get install qemu-system
To install NASM on windows use this link: shorturl.at/gowT2
(Look, it wasn't even a rickroll after all!)

Knowing nothing about OSes, that boot concept made total sense. Always wondered about that. Unfortunately doesn't seem to work when using WSL2 with Ubuntu... Get the error: "Unable to init server: Connection refused"

@DaedalusCommunity 3 роки тому

I'll look into that; if you find a solution before I do, tell me here :)

@@DaedalusCommunity Found it! First, you need to run the commands in the terminal that enable GUI here: wiki.ubuntu.com/WSL#Running_Graphical_Applications Then you need an application that acts as a display server (whatever that is). I used X410 (paid, has a free trial) but was just click and run. Though you have to enable "allow public access" in the settings. Then run the qemu command and a window pops up! Running an OS, inside an OS, inside an OS 😍 I think VcXsrv Windows X Server is free and would also work. I just tried X410 because it was easy.

@@JordanPlayz158 no, that's not vital for the purpose of level of abstraction of the operating system / machine, there's two levels, direct machine code and high level of abstraction code (programming languages).

@@JordanPlayz158 yes, but there's no formal definition, having GC doesn't make Java more or high or low level, nor does having Virtual Memory (we all take that for granted)

@gwentarinokripperinolkjdsf683 3 роки тому

@@monad_tcp personally. I consider any language wich does not have an obvious 1 to 1 conversion to machine code to be high level. For instance assembly is basically just machine code macros and could easily be compiled by hand, essentially assembly doesn't describe logic, it describes what bytes to put where. In C the compiler can really do whatever it wants as long as it gets the logic right, so C is high level. Just my 2 cents

ax is 'A' e"x"tended, the register A, but extended (with more bits, by having two parts). registers were named just like that, with letters, because naming them with numbers would be confusing, and they were made by engineers, if they were made by mathematicians, you would have greek letters.

I used to write boot sector programs in class when I was bored, I wrote them in Hexadeimal, and counted 510 bytes, and at the end added 55AA, It is really hard, but was really satisfying to get home and see that the looking random numbers to any other person, actually run as an operating system in a Virtual Machine.

I'll take some time to research after the exams in December, and will eventually record something before the second semester begins. Maybe I'll release some other video in the meanwhile, about the theory of programming languages, how to make one, and things I'm more comfortable with. I might as well try and merge the two, making a programming language and using it to program an OS, idk it's just an idea I had right now. Hope you'll be patient, I'll be back stronger than ever P.S.
