If you see

BOOTLDR

after you enter the set command, the image in bootflash is already being used as

the bootstrapper; go to step 13. Otherwise, go to step 12 and enter the commands to force the system
to use ni2−dboot−mz.121−5.bin as the bootstrapper.

rommon 1 > set

11.

Use unset BOOTLDR to remove the variable and sync to save the state of ROMmon, then reboot.

When the NI−2 boots, it uses ni2−dboot−mz.121−5da.bin as your bootstrapper.

rommon 2 > unset BOOTLDR

rommon 3 > sync
