Build scripts for BareMetal OS and its related utilities - The easiest way to create a BareMetal OS environment. These scripts will download and compile all of the components needed for using BareMetal OS.
The scripts in this repo depend on a Debian-based Linux system like Ubuntu or Elementary. macOS is also supported to build and test the OS and Assembly applications if you are using Homebrew.
- NASM - Assembly compiler to build the loader and kernel, as well as the apps written in Assembly.
- QEMU - Computer emulator if you plan on running the OS for quick testing.
- GCC - C compiler for building C/C++ applications.
- Git - Version control software for pulling the source code from GitHub.
In Linux this can be completed with the following command:
sudo apt install nasm qemu-system-x86 gcc git
BareMetal OS consists of several different projects:
- Pure64 - The boot sector and software loader. Pure64 is responsible for getting the computer into a clean 64-bit state on boot up.
- BareMetal - The kernel.
- Monitor - A simple command line interface.
- BMFS - The BareMetal File System utility.
- BareMetal-Demo - Various test/example programs.
git clone https://github.com/ReturnInfinity/BareMetal-OS.git
cd BareMetal-OS
./setup.sh
setup.sh
automatically runs the build and install scripts. Once the setup is complete you can execute the run.sh script to verify that everything installed correctly.
./build.sh
./install.sh monitor.bin
This command installs the boot sector, loader (Pure64), kernel, and simple command line interface (Monitor) to the disk image.
./install-demos.sh
This command installs the various test/example programs to the disk image.
./run.sh
Bochs does not support SATA drives so this is only useful for debugging the kernel. You will need bochs
and bochs-x
installed.
bochs -f bochs.cfg
./vmdk.sh
./vdi.sh
The VDI script rewrites the disk ID of the VDI file to avoid the disk warning in VirtualBox.
