        # RainOS

RainOS is a simple OS with a monolithic kernel, designed for old computers.

## Setup

To run it, you need a cross compiler for the i686 target. [Here](http://wiki.osdev.org/GCC_Cross-Compiler) you'll find some directions

To compile it, just type

```

$ make

```

The makefile assumes your cross-compiler folder is in the PATH.

Out-of-tree builds aren't tested.

You can also type ```make iso``` to create an ISO with the system or ```make qemu``` to launch it on QEMU.

## Minimal Requirements

 - A P6-level processor

 - 2 MiB of RAM
