tinyOS

A small kernel to understand low-level concepts (work in progress).

What does it do?

The kernel contains the following features:

It is loaded via GRUB legacy;
It maps the first 3MB of memory;
It manages paging (+ segmentation);
It configures software and hardware interrupts;
It sets up the keyboard for input;
It writes some data to COM1 serial port;
It logs what it's doing to the screen.

Building

This code requires bochs or qemu as emulator(s).

cd ~/path/to/repo

make run for qemu or make run-bochs for bochs
