In order to implement network management in OS-absent, W83792D/G provides ASF Response
Registers to meet ASF sensor spec. As a result, the network server is able to monitor several
environmental status of the client in OS-absent by PET frame values returned from W83792D/G,
including temperature, voltage, fan speed, and case open. In below is the ASF diagram:
