ASF PACKET DATA
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 number is shown as following:
The Entity ID is shown as following.
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.
The Entity Instance is shown as following.
FAN1 : 0Ah
FAN2 : 0Bh
FAN3 : 0Ch
The reference table of ASF 0.64 is shown as following.
