MikeOS v4.7.0

An operating system for x86 PCs, written in assembly language.

It is a learning tool to show how simple 16-bit, real-mode OSes work, with well-commented code and extensive documentation.





Features:
  • A text-mode dialog and menu-driven interface
  • Boots from a floppy disk, CD-ROM or USB key
  • Over 60 system calls for use by third-party programs
  • File manager, text editor, image viewer, games...
  • Includes a BASIC interpreter with 46 instructions
  • PC speaker sound and serial terminal connection


The code is completely open source (under a BSD-like license), and is written by Mike Saunders and other developers.

The .zip file:
The download contains the source code (see the source and programs directories), along with disk images for floppies/USB keys and CD-Rs in the disk_images folder.

Writing images:
You can write the images to a floppy disk, USB key or CD-R and boot your PC from them to test -- or use a PC emulator such as QEMU, VirtualBox or VMware. See the User Handbook below for a guide.

System requirements:
Minimum 386 PC with a keyboard and 1MB of RAM.

Handbooks:
The Handbooks are also included with MikeOS, in the doc directory.
