I'm installing a VIA EPMA ATX mainboard into an ATX box. It turns
out, the board maker and the box maker have slightly different ideas
about a few details. All the box's panel leads connect to a single
plug connector which doesn't fit the board. So I need to replace that
one plug connector with apparently four smaller ones. I have no
problem with this, except a detail.
Namely, according to the board manual's Front Panel Connectors page,
the board's panel connector includes two terminals for a green LED.
OK, an LED. And two terminals labelled "Green switch" which connects to
ground and SMI. Not OK: normally open or closed? And, *what is* SMI?
Careful reading through the English part of the board manual finds no
other reference in it to "SMI" nor words "S... M... I...".
So I find an "SMI" entry in my Scott Mueller, 15th ed, where it refers
to "System Management Interface." For some older 386 chip versions.
There, it relates to power management; but going back to my board
manual a closer look at possibly relevant parts of it turns up no SMI.
So there's that "Green LED" and "Green switch" and "SMI" and I think
it's real good practical practice, to know what these things are and
what they do. Before I power up this thing for its first smoke test.
But I can't find that information. Help!
