ZiZoyaOS

A toy operating system from scratch (in progress).

Demos:

ZiZoyaOS runs on a QEMU virtual machine/(qemu-system-i386) emulator:

ZiZoyaOS runs on a real PC (Old Sony VAIO):

Environment requirements:

1. nasm - assembler for assembly code
2. qemu - CPU emulator to debug our OS
3. gcc - compiler for C code

QEMU instruction:

In QEMU Windows version which executable files are separated, EXEs below can be used for testing:

1. qemu-system-i386
2. qemu-system-x86_64

How to run?

1. cd zzyos-v1.0.1/output
2. qemu-system-i386 -fda ZiZoyaOS.bin

Important logs:

1. 2020/12/21 It seems MingGW has some differences from Linux one which caused extra obstacles during developing, therefore, I decided to switch my environment to Linux in future developing. Current step: zizoya-kernel. Everything before zizoya-kernel(folder) is totally based on Windows environment.
2. I have abandoned this project long time ago and it is not an fully developed operating system technically. Feel free to continue working on it!
