This repo is an offshoot from my rustOS project. It has its own repo to separate the step of creating a freestanding binary and minimal Kernel in Rust from further steps in OS development for more comprehensibility.
Our minimal kernel is able to initialize the necessary hardware components, set up a basic execution environment, and write "Hello, World!" directly to the VGA buffer, thereby displaying the message on the screen :D

Simple guideline: Create bootimage with bootimage tool (we use the bootimage tool to link our kernel to the bootloader from the bootloader dependency, making it possible to skip our own bootloader implementation):

• install bootimage tool: cargo install bootimage
• run bootimage tool (execute in project dir): cargo bootimage

Use the created bootimage with qemu: qemu-system-x86_64 -drive format=raw,file=target/x86_64-simpleRustKerneltt/debug/bootimage-simpleRustKernel.bin OR Let the bootloader tool config in the cargo config.toml handle it with:

[target.'cfg(target_os = "none")']
runner = "bootimage runner"

(qemu should be started with "cargo run" with this setup

After running, qemu should display a simple "Hello World" from the bootimage

Disclaimer:
There are a lot of comments because I use this project myself to get more familiar with the Rust programming language, especially in low level use cases :)
