yhos

DOS-like operating system for x86 legacy hardware. These are it's features:

• Shell
• System calls via int 0x80
• Own executable format: yhSE (yhOS Static Executable, toolchain included)
• Virtual file system stored in RAM
• Dynamic memory allocator

Build

Requires clang, nasm, fasm and dcc (if available). To install the toolchain use homebrew (Build can take 0.5-17 seconds depending on your machine)

./make

Run

Make sure you have qemu-system-i386 installed

./run.sh

Makefile usage

You should sometimes use ./ymake and not make since ./ymake also rebuilds the makefile
