SEL record format used for Reset events
Timestamps
One of the internal BMC timers is used as a clock. Because this kind of clock does not
maintain the its value during a board power-down period, at each startup, the BMC
issues a SEL Get Time command to get the time from the ShMC and set the internal
BMC timer. This ensures that the BMC can set the correct event time-stamps.
The timestamp format used by the BMC conforms to the definition described in the
IPMI 1.5 specification.
Temporary Upgrade Storage
Temporary upgrade storage on the BMC local flash is a block of eight flash sectors used
as temporary storage for image files used during the CPLD and FRU upgrade process.
IPMI Protocol Support
The BMC fully supports the IPMI 1.5 rev. 1.1. This protocol is used for communication
with the ShMC over the IPMB. See
page 90
The BMC also supports the PICMG 3.0 OEM mandatory command set. See
8.2.2, “PICMG 3.0 IPMI Command Support” on page 95
support.
In addition, the BMC supports a set of Intel OEM commands and board-specific
commands. See
IPMI 1.5 Command Support
Table 35
grouped by general function, with an indication of whether the command is mandatory
(M) or optional (O) from the PICMG point-of-view. There is also information on whether
a given command is supported (S) or not supported (N) by the BMC.
