A prototype of a real-time operating system.
This will be a 
computing environment, without separating
the operating system from the programming language and applications.
Step 1: Get sources
$ git clone https://github.com/narke/Einherjar.git
Step 2: Compile and generate an ISO image
$ cd Einherjar/kernel
$ make all
Step 3: Run with qemu (by using 4Mb of RAM and the generated ISO image)
$ qemu-system-i386 -m 4 -cdrom ../build/roentgenium.iso
Step 4: Clean your build if you want
$ make clean
