— b filename boots from the boothelper image because it does not recognize the
device ID. This form of the command is used to netboot the image named filename.
Cisco 2600 series routers do not have a dedicated boothelper image ([rx]boot) as
used by some other Cisco routers. With Cisco 2600 series routers, the first image in
Flash memory is invoked as the default boothelper image anytime the ROM
monitor does not recognize the device ID in the boot command.
You can override the default boothelper image setting by setting the BOOTLDR
monitor environment variable to point to another image. Any system image can be
used for this purpose.
Options to the boot command are -x, load image but do not execute, and -v, verbose.
Use the Cisco IOS commands show version and show hardware to display the source
of the currently running image.
