Kern is a 32-bit OS based on the x86 architecture written in NASM Assembly and C. I'm working on a basic command line as well as a custom filesystem (filetable for now). It has a simple shell with some commands. (Use 'help' for a list of available ones)

Since there's always more to do, here are the todos.

Features

Filesystem (filetable)
Interactive Shell
Disk I/O
Font support (funky format)
1920x1080 Resolution, 32bpp
Physical memory manager

Building & Running

If you want to try kern for some reason, you can.

Tools

NASM
QEMU (for emulation)

Unix Like Systems

On MacOS

A cross compiler: $ brew tap nativeos/i386-elf-toolchain && brew install i386-elf-binutils i386-elf-gcc

Commands

$ make # Or 'make os'
$ make run # Run QEMU

I personally wouldn't recommend running this on real hardware, because it's untested and will just probably break you pc, but if you really want to, you can try it, but don't blame me if something goes wrong.

Known issues

If you run any of the bootloader stages or kernel form the shell, it will most likely break. (Maybe add an executable flag?)
fillCircle() in graphics.h is broken. No idea why, so no filled circles for you (i commented out the boundaryFill call in the function)
convertColor() doesn't work right, because i should be using floating point, but -mgeneral-regs-only doesn't let me :(
The soundtest command is very likely to get stuck on a note and play it forever. (Maybe a Sleep() bug?)
Not really an issue, bit QEMU's PIT is really slow and inacurate
