probably good.
Resetting Your Router Password

connects between the Cisco 675/678 and your PC's serial port)
- Login to the router (using Hyperterminal or other serial port based terminal application)
Note: connect using 9600 baud, 8-N-1, no flow control
- Remove, then restore power to the Cisco 675/678
- As soon as the Cisco 675/678's red ALARM light comes on, hit Ctrl-C a few times to enter ROM monitor
mode
- Enter the following two commands:
- CBOS# es 6 (erases sector 6)
- CBOS# rb (reboots 675/678)
