Configuration Card Personality Parameters Information stored on the configuration card includes the ethernet address, and personality parameters. The printer model configuration is determined by a combination of printer hardware capabilities. Feature value and ethernet address are configured at the factory, and are "read only". The feature value is fixed in the configuration card, and does not change. Ethernet address is stored only on the configuration card, and cannot be rewritten. The ethernet address is not written to the NVRAM chip. Personality parameters are a subset of network configuration parameters, which are populated to the configuration card over time as the system is configured by the customer. The personality parameters are copied, or "shadowed", from the main board's NVRAM chip to the configuration card during the normal operation of the printer. When the configuration card is inserted into a new printer, the personality parameters on the configuration card are written into the NVRAM chip of the new printer. When a printer is powered on, if it contains the configuration card of another printer, the personality parameters are automatically copied to the NVRAM chip. If the configuration card is removed, the system will reboot as a "B" (non-networking, non-duplexing) model..
