x64BareBones, starting a 64 Bits OS almost from scratch.

Introduction

x64BareBones is a basic setup to develop operating systems for the Intel 64 bits architecture.

The final goal of the project is to provide an entry point for a C kernel and the possibility to load extra binary modules separated from the main kernel.

It uses a modification of the Pure64 boot loader to boot up the basic system. The modification enables to load a greater payload than the restrictive 26k that Pure64 allows.

x64BraeBones is written primarily in C, there is a small loader written in x86-64 assembly (Intel idiom).

Environment setup

1- Install the following packages before building the Toolchain and Kernel:

nasm qemu gcc make

2- Build the Toolchain

Execute the following commands on the x64BareBones project directory:

user@linux:$ cd Toolchain
user@linux:$ make all

3- Build the Kernel

From the x64BareBones project directory run:

user@linux:$ make all

4- Run the kernel

From the x64BareBones project directory run:

user@linux:$ ./run.sh
