RqSA and LUN if event was generated from IPMB. 
Software ID if event was generated from system software. 
Byte 1 
[7:1] – 7-bit I
2
C Slave Address, or 7-bit system software ID 
[0] 0b = ID is IPMB Slave Address 
1b = System software ID 
Software ID values: 
  0001h – BIOS POST for POST errors, RAS Configuration/State, 
Timestamp Synch, OS Boot events 
  0033h – BIOS SMI Handler 
  0020h – BMC Firmware 
  002Ch – ME Firmware 
  0041h – Server Management Software 
  00C0h – HSC Firmware – HSBP A 
  00C2h – HSC Firmware – HSBP B 
Byte 2 
[7:4] – Channel number. Channel that event message was received over. 0h if the event 
message was received from the system interface, primary IPMB, or internally generated 
by the BMC. 
[3:2] – Reserved. Write as 00b. 
[1:0] – IPMB device LUN if byte 1 holds Slave Address. 00b otherwise. 
Event Message format version. 04h = IPMI v2.0; 03h = IPMI v1.0 
Sensor Type Code for sensor that generated the event 
Number of sensor that generated the event (From SDR) 
Event Dir | 
Event Type 
(EDIR) 
Event Dir 
[7] – 0b = Assertion event. 
1b = Deassertion event. 
Event Type 
Type of trigger for the event, for example, critical threshold going high, state asserted, 
and so on. Also indicates class of the event. For example, discrete, threshold, or OEM. 
The Event Type field is encoded using the Event/Reading Type Code.
