+As originally published, the VSA code compiled and assembled with older, commercially unavailable versions of Microsoft tools.  The OpenVSA code has been modified in order to build under a GNU toolchain so that it may be maintained and enhanced by a wider group of users. It still requires MASM or a compatible assembler, such as [http://www.japheth.de/JWasm.html JWasm]. Because of this, it wasn't integrated in the coreboot build process yet.
