</div><br /><br />
**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](https://wiki.osdev.org/GCC_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:
1. Type `./build.sh` to compile the system and to create an ISO
2. 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](https://github.com/ice-bit/iceOS/raw/master/imgs/iceOS.iso)(md5sum: `ab3d5b8307015461b44e62d0c2d42806`)
