Fiwix is a Unix-like operating system kernel designed for educational purposes and hobbyist development, targeting the i386 architecture. It implements many classic UNIX principles and aims to provide a clean, well-documented codebase that is both readable and easy to study. Fiwix offers a functional kernel that supports ELF binaries, a virtual file system, and standard system calls, making it a great platform for learning OS internals or experimenting with system-level programming. Its minimalist design helps users understand how key components like multitasking, filesystems, and memory management work under the hood.

Features

  • Monolithic kernel targeting x86 (i386) processors
  • ELF executable format support
  • Virtual file system with support for EXT2
  • Multitasking with POSIX-like process management
  • Basic memory management including paging
  • User and kernel space separation
  • System call interface compatible with standard C libraries
  • Bootable ISO image for testing and development
  • Clear, well-structured source code with educational value
