In this series, we’ll write our own 64-bit x86 operating system kernel from scratch, which will be multiboot2-compliant. In future episodes we might expand out to other architectures and bootloaders.

In this first episode, we write our initial boot code and also include a multiboot2 header so that it can be understood by bootloaders.

This operating system will be primarily written in C, but we’ll need some assembly as well for any of the hardware-specific code.

All the code is available on GitHub:
