My homebrew unix like kernel

NovaOS

Build: make

Run: make run

Description

The project started as a BIOS bootloader. When I managed to load some disk and enter protected mode (not knowing nor understanding assembly at all) I wanted to call an empty int main(void) written in C. That's how it all started. Needing to understand more what the University taught me about libc I started implementing my own (based on musl headers).

novaos's Issues

NVMe driver

It should be easier to implement than IDE ;P
There is one common interface with controller, you don't have to implement loads of devices.
