Operating System with Aetherix book

To celebrate the framework's release, I have also published a complete textbook: Operating System with Aetherix 📖.

It is a from-scratch guide to x86 operating system and UEFI application development. It breaks down how Aetherix works under the hood and teaches low-level computer architecture without using intermediate assembly language.

Inside the book:

  • No external tools: How Aetherix completely bypasses nasm, gcc, and ld.
  • Deep x86 internals: Manipulating ModR/M byte layouts, reading raw machine code hexabytes, and addressing memory segments.
  • Pure Python compilation: How a native C core handles binary machine-code encoding through standard-library ctypes bridges.
  • Extensible Ecosystem: How to use the native Hardware Abstraction Layer (HAL) to write custom peripheral drivers.

The entire framework is packed into a tiny, zero-dependency 204 KB footprint. The book is open-source.
