Programming CPLD(s) requires a vendor-
provided logic file and loader program which is
executed by booting up the system from a
floppy or OS-based executable containing the

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 have the network ports
operational.
