The assembler is a program that reads assembly source code and generates a binary output file or ELF .o file. The assembler reads a line at a time and writes the encoded program instructions for that line to the output file.
This document shows you how to write and build your first operating system in x86 assembly language. It explains what you need, the fundamentals of the PC boot process and assembly language, and how to take it further.
3 wrz 2024 · This journey will empower you, the intrepid coder, to craft your own basic OS using the fundamental language of computers: Assembly. Stepping into this world means shedding the comforts of high-level languages and embracing the raw power (and challenges!) of communicating directly with the hardware.
Assembly language is typically used in a system's boot code, the low-level code that initializes and tests the system hardware prior to booting the operating system and is often stored in ROM. ( BIOS on IBM-compatible PC systems and CP/M is an example.)
