FelipOS

A simple OS programmed in x86 Assembly real mode (16-bit) inspired by MikeOS.

Requirements

  • Netwide Assembler (NASM)
  • ImDisk tools
  • QEMU, Bochs or similar for emulation
  • A 1.44MB floppy disk or USB key for real hardware

Features

  • A bootloader that can search for a kernel file on the root directory, load and execute it.
  • A basic kernel with a command line (shell), some builtin commands and a "graphical" menu.
  • Can execute external binary programs.
  • Code is a complete rewrite and tries to keep compatibility with MikeOS system calls/interface.
    • Runs most original binary programs for MikeOS. \o/
  • (Probably) Lots of bugs!

Notes

  • Some random notes taken when studying the source for MikeOS.

Testing

Install requirements and execute:

run.bat

Note: Edit executable paths if needed.

For use on real PC hardware, a floppy image can be written to a physical 1.44 MB floppy disk or directly to an USB drive (some BIOSes can emulate a floppy disk on boot).
