This is a tiny hobby OS kernel that boots into 32‑bit mode and writes directly to the VGA text buffer at 0xB8000. The build produces a 32‑bit kernel.bin linked with a boot object via a custom linker script. The runtime is freestanding (no libc), and text output is implemented manually.

./run.sh

This is mainly run on Linux; I have yet to try it on other platforms. Basically, the boot process may be Linux x86 specific.

It does not build on macOS currently.

Just for fun :)
