System Management Bus & Devices?

  1. Way over my head, here. :confused:
    Trying to learn.

    So, here's your opportunity to
    show off your expertise! :D

    Installing a new board - 2nd time,
    but this one is way more complicated
    than the last one which was a number
    of years ago.

    The instructions show how to enable or disable
    the SMBus 2.0 via jumpers, default is disabled.

    From what I've found on it, enabling it will allow
    a device to tell the board or board system about
    itself? Is that a basically correct interpretation?

    Next, would it not be good if that were enabled?

    How does one tell whether a device is set up for
    that or not? Or is there such a thing as being
    set up or not being set up for that?

    Also talks about the option of connecting an
    "SMBus Management Device" - pray tell, just
    what IS that? Any what's the benefit?

    Appreciate you sharing your wisdom!

    SMBus means System Management Bus, it is used in PCs for BIOS operations and other services. like many modern technogies, it was invented by intel in the 90's.

    you want to leave it enabled. it is automatic and there's nothing you need to worry about/do.

    For once, something relatively simple!

    From what (little) I had read - I figured it was something
    like that.

    Never heard of an extermal SMBus device and didn't know
    what it does for sure and/or why I'd want/need one -
    I guess it would be something that would allow manipulation of the system or something?

    As long as I don't need one, I guess it doesn't matter! :approve:


    I was wondering why the default would be disabled
    on a new board - maybe they were expecting the
    user to enable it when something was plugged in.

    It would help if you tell us the brand and exact model of your motherboard.
