Way over my head, here. Trying to learn. So, here's your opportunity to show off your expertise! 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!
