W83791D/G
W83791D/G can uniquely serve as an ASF sensor to respond to ASF master’s request for the
implementation of network management in OS-absent state. Through W83791D/G compliance with
ASF sensor spec, network server is able to monitor the environmental status of the client in OS-absent
state by PET frame values returned from W83791D/G, such as temperatures, voltages, fan speed,
and case open. Moreover, W83791D/G supports SMBus 2.0 ARP command to solve the problem of
address conflicts by dynamically assigning a new unique address to W83791D/G after W83791D/G’s
UDID is sent.
Through the application software or BIOS, the users can read all the monitored parameters of the
system from time to time. A pop-up warning can also be activated when the monitored item is out of
TM
TM
the proper/preset range. The application software could be Winbond's Hardware Doctor
, Intel
LDCM (LanDesk Client Management), or other management application software. Besides, the users
can set up the upper and lower limits (alarm thresholds) of these monitored parameters and activate
one programmable and maskable interrupts. An optional beep tone could be used as a warning signal
when the monitored parameters are out of the preset range.
