Microsoft decided not to implement support for it in Windows, it's essentially there for embedded style x86 platforms running Linux so they don't need to reimplement so many wheels and can just reuse existing DT bindings but it causes problems if you want to run Windows (and possibly some of the enterprise Linux distros, I can't remember if any of them had concerns about it) on the platform. --p8mP+8RrBGerSNjm Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAl9GyfsACgkQJNaLcl1U h9C2Xgf/U5iXD2Fm8wqFbVSfKajaqTfB7OsyGR/oZoQPfSiJrkaSENbsx4sevNjQ ZrQ8z8Opo6Zi45t872miyS3Ib22XSU9/obKAkqaLxdVAWpGHvbf0qIv/mqh1VoQw gcuJojxCD2M0k84Oww40ud41LKKLVPhFxLeSwKPJhvsGC2f49Lki2TkdggeY/4lY r/TXKE96dl0TCwL1qvKFsC9Mc0LqIQKDKnsJSOSi9MwwEZQY+w/GWuhS3Iyl6EnX wmsiwv+fc4lnwc/Uq9Kd0qzNTqmgeZ1d7j3mSvWb6Ptpr9vN/3NC4QvcELcFzxD1 z9VjMG1tUZOZPqskLzZ+fYa6hwf4Ww== =WdfB -----END PGP SIGNATURE----- --p8mP+8RrBGerSNjm--
