The W83791D/G is complying ASF 1.0 specification and the value is 0 x 68.
The ASF specification indicates that the Sensor Device is the SMBus address
of the sensor that caused the event for the PET Frame. Therefore, the Sensor
Device of the W83791D/G is APR assigned address.
The sensor number for case intruded is 11h
These ID are defined in Table 28-11 of IPMI v1.0 specification. This value is
programmable because that may be used in add-in-card or connected to other
device.
Monitor (0x01): That is represented the monitored fan count is under the limit
count.
Critical Condition (0x10): that is represented the monitored fan count is over
the limit count.
The Entity ID is 23h for case intruded
