I've just spent a bit of the past two months getting ReactOS working on a system that uses the Vortex86DX CPUs (similar to the RoBoard and eBox systems). I've created the start of a web page about this project:
If your RoBoard (or eBox) has a BIOS selection for "Standard IDE Compatible" then ReactOS might work on your system. There is still a bit of work to get ReactOS running on older Vortex86DX systems that don't have that BIOS option.
This new OS option looks like it could be fun and interesting and your help is encouraged.
