No- SAF-TE was what an *early* version of SES looked like. Then it went it's
own way. Currently there is a bunch of SAF-TE chips out there (e.g. GEM-I and
GEM-II), but the spec is no longer owned by anyone and www.safte.org
disappeared over two years ago, so the ability to even find the spec is
limited to finding those who had downloaded both the .doc and the addendum.

Somebody out there correct me if I'm wrong.

At any rate, you *can* emulate SAF-TE within SES. In fact, it's better to
create an SES driver and then map SAF-TE into it (which is what I did for
Solaris && *BSD). There are a couple of global status items that don't map
easily- and the one wierd thing is to map the overtemp bits (all 17 of them)
into SES temperature elements. Plus the conversion of SAF-TE temp ranges for
SAF-TE temp elements into SES temperature elements (different ranges). What a
PITA.
