- Опубліковано 12 чер 2024
- Welcome to my x86 Assembly tutorial! This video is perfect for beginners looking to dive into low-level programming. In this tutorial, we'll cover everything you need to start your journey in assembly language:
Setup the Environment: Learn how to set up your development environment to write and test x86 assembly code.
Registers & MOV Instruction: Understand what registers are and how to use the MOV instruction to transfer data.
Basic Arithmetic Instructions: Master essential arithmetic instructions like ADD, SUB, MUL, DIV, and the use of square brackets for memory addressing.
Stack Operations: Explore the stack and how to use PUSH and POP instructions.
Labels & Flags: Learn how to use labels for marking code locations and understand flags for condition checks.
Control Flow: Implement control flow in your code using CMP and JMP instructions.
Loops:Build loops with assembly instructions to control your program flow.

OMG thank you so much! this will be really helpful for me I really appreciate that!
Thanks, comments like this are super motivating
this guy is getting better and better with each video - incredible to see 🍿. keep up the good work 👾
Thank you! Please continue with this assembly tutorials 👏👏
Wow! Very well done! I'm loving it!
Hope this will be a multiple part series ‼️
Nice I hope you have next episodes about assembly 😍😍
tysm, i wanted to learn assembly for a while now and I did try on the past but gave up because i didn't find any resources (or didn't search enough :P) and thanks to this I can now actually write and read some basic assembly, I know it takes a very long time to make these videos but I hope you make more, subbed :)
Search for intel developer manual for 80386.
Please continue sir please
I like to use the DosBox emulator for using the x86 assembly programming language, because DosBox emulates a PC with MS DOS 5 and in DOS there is no protection to access all hardware components directly without to get a message of a protection violation. In Windows/Linux we have to use system calls to use the hardware, but not in DOS. In DOS we can controll the hardware directly with our own executable, if we know how to do it. So in DOS we have a lot more to learn how the hardware components work together. It starts by writing directly into the screen memory and go through the point to switch the working mode of the CPU.
Stack segment: last in first out, pointer is moving, data is going lost after popping the last value from the stack, used by calling convention
Data segment: pointer to memory location, no data get lost, read/write access from inside and outside nested sub routines without to care where the stack pointer is
I am on an Android tablet with a Dosbox emulator app installed and i like to use x86 assembly to create tiny executable with a little help from debug. I am not familar with an ARM CPU, but the emulation of intel 80386/80387 works fine.
hope you take us along with you through your path of learning assembly i recently saw a video on off by one security about process injection and there was a lot of assembly in it as they open the code in gidra to see the break point and all to inject a malicious code onto a legitimate process for process hollowing i didnt understand much as i ddint know how the assembly works and how he found the break point and all
One byte of 8 bits can divided into = 4 bits high nibble + 4 bits low nibble. And this make it easy to read some bits as hexadecimal values without to know the decimal value of the byte.
4 bits hexadecimal
0000 = 0
0001 = 1
0010 = 2
0011 = 3
0100 = 4
0101 = 5
0110 = 6
0111 = 7
1000 = 8
1001 = 9
1010 = A
1011 = B
1100 = C
1101 = D
1110 = E
1111 = F
Good work.
Thank you ...
mov eax, 5
shl eax, 3 ; = shift left 3 times
shl 1 time = multiply by 2....shl 2 times = multiply by 4.......shl 3 times = multiply by 8
The keyword colouring should be adjusted for dark mode. Other than that good video, thanks
I know, but i couldn't find any other good syntax highlighter
@@screeck perhaps there is a json or config file located somewhere, you don't need to change whole highlighter
suggestion: dont play with assembly, you're gonna $uck your system, at least do it within sandboxed envs
On Windows i used the DosBox emulator to mount a folder as a drive. And inside the emulation i can read/write all files in this folder, but not the files of the host system.
Imagine with 32 bit we can make an executable that start with decimal values attached for input with up to ten ASCII 4294967295 to convert it to 8 hexadecimal ASCII FFFFFFFF for output.
