firmware
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. System
loaded with arbitrary data in firmware
memory would not operate.
No explicitly protected but special
applications are needed to communicate
through the LOMs to reprogram this ROM.
