4-5. Flash ROM
There is a Flash ROM Card PCB prepared for the CPU Module and Ether Card PCBs. The Flash ROM Card PCB is
used if something wrong happens while updating the software (e.g. power shutdown, blackout). The Flash ROM Card
PCB allows to boot up DV40, copy the system software in the Flash ROM Card PCB to the Flash ROM on the CPU
Module and Ether Card PCBs using this “Flash ROM” Service Menu. Furthermore, you can rewrite the program inside
the Flash ROM on the Flash ROM Card PCB. In other words, by rewriting the program, only one Flash ROM PCB can
work for both the CPU Module and Ether Card PCBs. Refer to the following procedures.
