baremetal assembler on raspi B A super basic os, if it can even be called that, writen for the rasberry pi B in assembler based largely on Alex Chadwick's excellent turorial: http://www.cl.cam.ac.uk/projects/raspberrypi/tutorials/os/index.html

As of yet it really doesn't do much other than blink an led using an interupt, display some text and display a picture, and send some text (GPU memmory address) over serial (uart)

Be warned: The code is probably of poor quality and the comments probably more so. Ive tried to explain what the various bits and pieces do but but how well is debateable!!! ;)
