Original: Building a chikku OS

Short summary

Comprehensive tutorial: building a minimal operating system (mintOS) from scratch using C and assembly language. Covers the full boot sequence (BIOS/UEFI → GRUB → kernel), VGA text-mode memory programming, GRUB bootloader configuration, and keyboard input handling with scan-code translation. Includes production-ready code: Makefile automation, multiboot-compliant assembly, kernel C implementation, and linker scripts—all testable in QEMU emulator.

  • •Step-by-step OS development from bootloader through kernel initialization
  • •Low-level systems programming: assembly, memory-mapped I/O, VGA, GRUB configuration
  • •Complete working code with Makefile, boot.asm, kernel.c, linker script, and QEMU testing

Generated with AI, which can make mistakes.
