Bit 13
Bit 13 determines the server response to a bootload failure. If boot commands are in the configuration
file, the router software processes each boot command in sequence until the process is successful or the
end of the list is reached. If the end of the list is reached without a file being successfully booted, the
router will retry the netboot commands up to six times if bit 13 of the configuration register is set,
otherwise it will load the operating system software available in ROMmon. If bit 13 is not set, the router
will continue to netboot images indefinitely. The default setting for bit 13 is 0. If bit 13 is set, the system
boots the boot helper image found in boot flash memory without any retries.
Bit 15
Bit 15 enables diagnostic messages and ignores NVRAM contents.
