Simple kernel written in C for Intel x86 CPUs

About iceOS

iceOS running under QEMU

iceOS is a x86 monolithic kernel written in C from scratch.
This project doesn't aim to be a fully functional operating system with tons of drivers and graphical applications, it's just a learning tool to teach myself concepts like Operating Systems, Computer Architecture and Digital Electronics.

Installation

Requirements

Before generating an ISO you have to compile a cross compiler and you also have to install those packets:

nasm
bochs
grub
mtools(if you are on Arch Linux)

Then you can run those commands:

Type make all to compile the system and to create an ISO
Type make run to start it in QEMU or make bochs to start it with bochs(only for debug purposes).

Otherwise you can download an already compiled ISO file here(md5sum: ab3d5b8307015461b44e62d0c2d42806)

Features

iceOS already have/will have the following features:

Bare metal booting;
VGA driver;
Interrupts implementation;
PIC & PIT implementation;
PS/2 driver;
Support for x86 architecture;
GRUB as bootloader;
