SMBIOS physical memory array (type 16): SMBIOS physical memory array (type
16) is included for reference.
Field IPMI definition BIOS-specific implementation
Generator ID 7:1 System software ID or IPMB slave
address. 1=ID is system software
ID; 0=ID is IPMB slave address.
7:4 0x3 for system BIOS
3:1 0 Format rev ision. Revision of the data format for
OEM data bytes 2 and 3. For this revision of the
specification, set this field to 0. All other rev isions are
reserved for now.
0 1 = ID is system software ID.
As a result, the generator ID byte will start from 0x31 and
go up to 0x3f, in increments of 2 for events logged by the
BIOS.
EvMRev Event Message Revision This field is used to identify different revisions of the
Event Message format. The rev ision number shall be 03h
for Event Messages that comply with the format given in
this specification.
Sensor Type 0xC for memory errors
Sensor Number Number of sensor that generated this
event Unique value for each type of ev ent because IPMI
specification requires as such. This field has no other
significance. Should not be displayed to the end-user if
the event is logged by BIOS.
Event Direct /
Event Type 0x6F if event offsets are specific to the
sensor 7 0= Assertion Event, 1 = Deassertion Event
6:0 0x6F
Event Data 1 7:6 00 = unspecified byte 2; 10 = OEM
code in byte 2.
5:4 00 = unspecified byte 3; 10 = OEM
code in byte 3. (BIOS will not use
encodings 01 and 11 for errors
covered by this document.).
3:0... Offset from Event Trigger for
discrete event state.
Follow IPMI definition. If either of the two data bytes
following this do not have any data, that byte should be
set to 0xff, and the appropriate field in event data 1 should
indicate that it is unspecified.
3:0 is 0 for single bit error and 1 for multi-bit error.
Event Data 2 7:0 OEM code 2 or unspecified. For format rev 0, if this byte is specified,
7:6 Zero based Memory Board number. Matches the
number of type 16 entry in SMBIOS table. For
example, card 0 corresponds to the first type 16 entry
in SMBIOS tables. If all DIMMs are onboard, this
field will always be 0.
5:0 Zero based DIMM number on the card. DIMM 0
corresponds to the first type 17 record in SMBIOS
tables for that memory card.
Event Data 3 7:0 OEM code 3 or unspecified. If format rev is 0 and if this byte is specified, Syndrome
Byte.
