Nope OS is a simple OS kernel bundled with a BASIC interpreter, bringing 

back the 80s home computing feeling.

Supported Platforms

===================

x86 compatibles.

Compilation & Usage

===================

Pre-requisites (Ubuntu):

    sudo apt install git nasm build-essential qemu-system-x86

Download:

    git clone https://github.com/d99kris/nopeos && cd nopeos

Build (outputs `kernel.bin` and `kernel.iso`):

    ./build.sh

Run in QEMU:

    ./run.sh

Stop emulation by pressing ESC.

Optionally build and generate img disk image (`kernel.img`):

    ./build.sh -i

Download Pre-Compiled Disk Images

=================================

Download links:

- [Nope OS v0.1 IMG](https://github.com/d99kris/nopeos/releases/download/v0.1/nopeos-0.1.img) (2MB)

- [Nope OS v0.1 ISO](https://github.com/d99kris/nopeos/releases/download/v0.1/nopeos-0.1.iso) (0.5MB)

These disk images may be used in a virtualized environment or on a physical

machine.

**Warning:** For usage on a physical machine, take note that Nope OS is just a

proof-of-concept and may contain bugs that could corrupt your system.

Booting a Physical Machine from USB Drive

-----------------------------------------

Download the IMG disk image above and use for example `dd` or

[balenaEtcher](https://www.balena.io/etcher) to write the image to a drive.

Design Notes

============

The implementation is based on [bkerndev - Bran's Kernel Development Tutorial](http://www.osdever.net/bkerndev/Docs/title.htm) and the [TinyBasic interpreter](http://www.ittybittycomputers.com/IttyBitty/TinyBasic/).
