Do you want to win your robot tournament with RoBoard? If the answer is "Yes", then you should try this Operating System: KolibriOS - http://www.kolibrios.org
It is written 90% in Assembly, has a fully-featured GUI, and still fits in 1.44MB floppy image. Open-source, freeware, distributed under GPL license. On Vortex86DX CPU (the one used in RoBoard) it boots from power-on till working system in less than 10 seconds. More information is available on KolibriOS wiki: http://wiki.kolibrios.org/wiki/Main_Page
Work on porting KolibriOS to Vortex86 SoC is already in progress, but you still can help and are invited to do so!
So far we have R6040 network card working, RDC R3010 HD Audio (the one used in Vortex86MX) working. We are looking for people who would like to test the system on their RoBoard, as well as help us write the drivers for the Servos / GPIO / I2C / PWM etc.
I have written an introductory article here: http://www.deviceonchip.com/index.php?o ... &Itemid=85
(and also instructions to install a working KolibriOS image).
You are welcome to post any questions and comments in this thread, but also invited to write them on KolibriOS developers forum: http://board.kolibrios.org/index.php
The forum members mostly speak Russian, but if you write your question in English, then someone will reply you in English as well
Ideally, KolibriOS can run even inside RoBoard / eBox BIOS (it has enough space for that), but we need RoBoard manufacturer cooperation for doing that (BIOS includes a "Virtual Floppy" support that can be installed inside BIOS flash chip, but we cannot figure out how to use this option and the manufacturer did not wish to answer us
) So maybe now, after this post, there will be enough people interested so that manufacturer will answer
