Author: emc2 Date: Sun Jun 3 23:54:18 2012 New Revision: 237023 URL: http://svnweb.FreeBSD.org/socsvn/?view=rev&rev=237023 Log: Results of some exploration. The end result of this is a better understanding of how to build EFI applications using the build tools. I've also done a fair amount of exploring the EFI API, though that can't be reflected in actual code changes.
