I have write a new release of a tool that i named RemoteBIOS. This tool, can help us, to test your Coreboot development for new mainboards. If one is interesting on this tool, can download it in Sourceforge. Is only in the first stage of a more complex project. I use for my mainboards, and help me a bit. Also the project have a subtool needed for build the project, that helps to compile with gcc, using a virtual MMX or XMM stack. Sorry, can not be valid for all machines.
