The BMC recovery boot loader contains several options that are password protected.
These options are not intended for customer use because their use can invalidate the
software in a way that requires additional hardware for board recovery.
BMC Operational Images
The BMC’s local flash contains two BMC operational images. The BMC allocates three
sectors of flash memory for each operational image and its descriptor. One of these
images is loaded by the BMC Initial Loader from flash to RAM and then executed. The
selection of a proper operational image is done according to the Status Word stored in
the BMC EEPROM memory.
Section 11.5, “Remote BMC Firmware Upgrade” on page 158
functionality and the format of the BMC status word.
Each of the two BMC operational images has an accompanying “properties image”
descriptor containing image control information that needs to be verified before the
image is stored on flash. See

BMC Power On Self Test
The Power-On Self Test (POST) performs basic tests on the BMC and the main
baseboard components that the BMC depends on. These tests do not require any cables
to be connected.
BMC POST can be executed as a set of short or long tests:
The short POST option provides the ability to shorten BMC boot time.
The BMC can execute the following tests within the confines of POST:
Interrupt (IRQ) POST
Interrupt controller verification testing is available, including simulated interrupts.
• The long POST set contains all possible tests the BMC can perform.
• The short POST executes only selected tests depending of the BMC’s short POST
