The server creates a default boot filename as part of the automatic configuration processes. To form
the boot filename, the server starts with cisco and links the octal equivalent of the boot field number,
a dash, and the processor-type name. Table B-3 lists the default boot filenames or actions for the
processor.
Note A boot system configuration command in the router configuration in NVRAM overrides the
default netboot filename.
