Intel AMT "M" State LED
The board has an Intel AMT "M" state LED (red), located near the Channel A DIMM
socket. The "M" state is based on Intel ME status, as follows:
•
M0 = Intel ME is in full control in S0
•
M1 = Intel ME is in full control in S3-S5 for "out of bound" Intel manageability
•
Moff = Intel ME is in sleep state after Intel ME timeout has occurred
