LED POST
LED POST performs simple LED tests. Each LED is lit in all the supported colors (for a
noticeable amount of time).
KCS POST
At the stage POST is being executed, KCS peripherals are not yet powered. Only simple
register access tests are performed.
Timer Test
There are four timers supported in the BMC. The following test is performed:
System Event Log
The System Event Log (SEL) is a block of four sectors on the BMC local flash allocated
to store IPMI events. Event handling, storage, and retrieval procedures are described in
the following sections. Currently, the SEL is 128kB long and it is not circular (new
events do not overwrite old ones, and are discarded if the SEL is full). The BMC SEL
architecture is consistent with the definition in the IPMI 1.5 specification.
SEL Descriptor
The SEL Descriptor occupies the first 13 bytes of SEL storage memory and has the
format given in
a response to the Get SEL Info command.
BMC SEL descriptor
Event Logging
The BMC stores the following events in the event log:
Byte
1:2
3:4
5:8
9:12
13
† Timestamps used by SEL functionality have a format that conforms to the definition described in the
IPMI 1.5 specification.
• Load the timer registers with a certain value and verify that an interrupt is
• All IPMI events generated by the BMC
• All IMPI events generated by the NPU (or AP) and forwarded by the BMC
• All reset events (entire board, NPU, or BMC)

generated after the time elapses.
Description
Number of log entries in the SEL, LS byte first
Free space in bytes, LS Byte first. FFFFh indicates that 65,535 or more bytes of free space are
available.
Most recent addition timestamp†. LS byte first.
Most recent erase timestamp. The last time that one or more entries were deleted from the log;
LS byte first.
Operation Support
7:7 – Overflow Flag. 1b = Events have been dropped due to lack of space in the SEL.
6:0 – Reserved. Write as 0b
