CMike

CMike is an operating system written in C (and a tiny, tiny bit of supporting Assembly), which aims to be binarily compatible with MikeOS 4.6

You can download the latest release from the Releases section of this repository. The project is licensed under the MIT License. Current version is 0.1.0.

System requirements

Exactly the same as MikeOS:

• a 386 class PC
• 192 KiB of system memory
• CGA or compatible
• a keyboard
• a floppy disk for boot (for now there are problems with booting off hard drives)

Software might require additional things, but this list is everything necessary for just CMike.

Usage

Unlike MikeOS, CMike only comes with a command line prompt. It's simple to use, run help to list available commands and if you want to execute a binary file, type its full name (including the extension) and press Enter.

Build

In order to build CMike you need:

• ia16-elf toolchain
• nasm
• mtools
• make
• qemu for make run

There's a Makefile in the root of this repository. It supports the following targets:

• make all - build everything, including the disk image
• make bootloader - NatLoader, boot sector used by CMike
• make kernel - the kernel, obviously
• make libcmike - front end library for MikeOS/CMike C programs
• make programs - CMike software
• make diskimg - build the floppy disk image (diskimg/cmike.flp)
• make run - runs QEMU with diskimg/cmike.flp in floppy drive A: and PC speaker enabled
• make dist prepare a cmike-VERSION.tar.gz archive with cmike.flp, all files from misc directory and LICENSE

Have fun. <3
