The global Open Firmware environment includes the partition manager component. That
component is an application in the global Open Firmware that establishes partitions and their
corresponding resources (such as CPU, memory, and I/O slots), which are defined in partition
profiles. The partition manager manages the operational partitioning transactions. It responds
to commands from the service processor external command interface that originate in the
application that is running on the HMC.
The ASMI can be accessed during boot time. Use the ASMI to boot to an Open Firmware
prompt.
