Nigel Barink 7d6c823d79 Basic Launch of Higher half kernel
We now can launch the kernel at 0xC0000000 (or 3 GiB mark) with paging enabled.
A lot of early main is currently not executed to keep debugging as simple as possible
during the initial testing of higher half kernel loading.

A lot of the implementation is straight from wiki.osdev.org/Higher_Half_x86_Bare_Bones. Thanks to all the folks
who keep that wiki updated, its really resourceful.

Writing an Operating system

As a learning experience!

Inspired by people like Linus Torvalds and Andreas Kling

Scrolling the terminal
The first scrolling boot screen. 😲

Interrupt handeling
W.I.P - Working on interrupt handling

Multiboot integration
Multiboot information can be read by the kernel.


The goal

Writing a hobby operating system to better understand the basic building blocks of any operating system.Initially I'd like for my operating system to be able to run bash.


Operating System Technical specs/details

The operating system can print strings to the screen. The terminal/screen has scrolling so the latest messages are visible on the screen.
