Hi, To my understanding, Andre Fischer wrote the original BootManager; the executable for which is now in the ETHZ SVN archive. https://svn-dept.inf.ethz.ch/svn/lecturers/a2/trunk/source/ Documentation formerly on the OCP server is now available from WayBack. https://web.archive.org/web/20151127045022/http://www.ocp.inf.ethz.ch/wiki/D... Most likely it was written by Andre. Hopefully someone can confirm or correct that statement. The executable should work on any PC where A2 works. It worked for S3 and should work as well for V4. For a Unix-like system, chain loading can be applied. I appreciate that WayBack prevents loss of the document but don't consider it a good permanent home. I'm tempted to add it to the wikibook, with appropriate acknowledgement of course. Any comments about that? Can anyone confirm the author? Thanks! ...
