(no key pressed) After a few seconds, the router startup process continues.

[Y]Load the version, without any patches, from EPROM onto the RAM, and run the full version. Go to step 6.

[S]Load and run the version and patch determined by the INSTALL parameters from the flash file system, ignoring any boot script or any previous configuration stored in NVS.

[N]Load from flash to RAM the version and patch determined by the INSTALL parameters, and run using the current configuration stored in NVS (if any), ignoring any boot script.

During the start-up process the router generates four different types of messages. All messages are preceded by one of the words INFO, PASS, FAIL, or ERROR. The meaning of these words in the context of the messages is shown in the following table.

Table 5: Router start-up message classes
