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).
