Table of contents

Build from source on Linux

Main Kernel

Requirements:

Steps:

  1. Make sure rustup is installed:
rustup --version
  1. Create a local clone of the repository:
git clone [email protected]:adamperkowski/highlightos.git && cd highlightos
  1. cd into the kernel/ directory:
cd kernel
  1. Build the bootable binary:
cargo bootimage --release

This command will create the target/target/release directory in which you'll find the bootimage-hlkernel.bin binary file.

HighlightOS ASM

Requirements:

  • Git version control system
  • NASM Assembly compiler

Steps:

  1. Create a local clone of the repository:
git clone [email protected]:adamperkowski/highlightos.git && cd highlightos
  1. cd into the asm/ directory:
cd asm
  1. Compile the bootable binary:
nasm -f bin boot.asm -o boot.bin

This command will generate & place the boot.bin file inside of the current directory.

Run in QEMU on Linux

Requirements:

Steps:

  1. cd into directory that contains the binary.
  2. Run the following command:
qemu-system-x86_64 -drive format=raw,file=<your_binary_filename>.bin

Important

Replace <your_binary_filename> with the actual name of the binary you have downloaded/built.

Run on real hardware

You can also flash the binary image onto a USB stick and boot it on a real machine.

You can flash it by running the following command:

dd if=<your_binary_filename>.bin of=/dev/sdX && sync

Important

Make sure to replace <your_binary_filename>.bin with your downloaded/compiled binary name and make sure to replace /dev/sdX with your USB's actual partition number. Any data on it will be lost!

Note

You can choose the device to boot off of from your BIOS boot menu (accessible by pressing F8 or F12).

Double-check that your motherboard is capable of booting legacy media(s), as HighlightOS is not UEFI-compatible yet.
