Intel SE7520BD2 Technical Product Specification

Intel® Server Board SE7520BD2 Technical Product Specification Error Reporting and Handling
Revision 1.3 Intel Confidential

5.4.3.3 FRB-2 Error Events
Table 65. FRB-2 Error Events
Field IPMI Definition Intel® Server Board SE7520BD2 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 revision, 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 revisions 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.
Sensor Type See Table 30.3 in [IPMI_1]. 0x7 for processor related errors
Sensor number Number of sensor that generated this event Unique value for each type of event because IPMI
specification requires that. This field has no other
significance, and it should not be displayed to the end
user if the event is logged by BIOS.
Type code 0x6F if event offsets are specific to the sensor 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.
If Event data 2 and event data 3 contain OEM codes, bits
7:6 and bits 5:4 contain 10. For platforms that do not
include the POST code information with FRB-2 log, both
these fields will be 0. BIOS either should specify both
bytes or should mark both bytes as unspecified.
According to IPMI 1.0 specification, Table 30.3, Byte 3:0
is 03 for FRB-2 failure during POST.
Event Data 2 7:0 OEM code 2 or unspecified. For format rev 0, if this byte is specified, it contains bits
7:0 of the POST code at the time FRB-2 reset occurred
(port 80 code)
Event Data 3 7:0 OEM code 3 or unspecified. For format rev 0, if this byte is specified, it contains bits
15:8 of the POST code at the time FRB-2 reset occurred
(port 81 code). If the BIOS only uses one byte POST
codes, this byte will always be zero.

FRB-2 error, failing POST code information not available 0x03 0xFF 0xFF
FRB-2 error, BIOS uses one byte POST codes. The last POST code before FRB-
2 reset was 0x60.

FRB-2 error, BIOS uses one byte POST codes. The last POST code before FRB-
2 reset was 0x1942.
