is executed by booting up the system from a floppy or OS-based executable containing
the firmware file and the loader. A system loaded with arbitrary data in firmware memory
will not operate.
LOM Configuration
Data
Loading flash memory requires a vendor-provided firmware file and loader program which
is executed by booting up the system from a floppy or OS-based executable containing
the firmware file and the loader. LOMs loaded with arbitrary data in firmware memory
would not operate.
