NPU boot configuration parameters (Continued)
The Boot Configuration parameters can be changed using dedicated Boot Monitor
commands. The BMC and ShMC are also able to change these parameters via a
dedicated OEM FRU record.
Initial Loader
The Initial Loader occupies the first sector (or sectors) of flash memory associated with
a particular processor, that is, the boot sector. The boot sector must be locked (write-
protected) to avoid the possibility that a user accidentally overwrites the boot sector
with an incorrect image, which would render the board unusable and requires
reparation with hardware tools such as a JTAG flash programmer.
The Initial Loader is the first code that the processor executes from flash after it is
released from the reset state (note that the BMC controls reset of the NPU). This code
performs the following actions:

Description
The static IP configuration for debug Ethernet interface. The following information
is stored here:
A flag indicating the type of IP configuration used for the base interface #1 during
run-time image loading. This flag can have one of two values:
The static IP configuration for base interface #1. The following information is
stored here:
A flag indicating the type of IP configuration used for the base interface #2 during
run-time image loading. This flag can have one of two values:
The static IP configuration for base interface #2. The following information is
stored here:
A script containing a set of commands that are executed by the Boot Manager to
load the run-time image for the NPU.
