Initial Configuration - Cisco 3845 - Security Bundle Router Software Manual

Understanding the Boot Process
•
•
The boot loader provides access to the flash file system before the operating system is loaded. Normally,
the boot loader is used only to load, uncompress, and launch the operating system. After the boot loader
gives the operating system control of the CPU, the boot loader is not active until the next system reset
or power-on.
The boot loader also provides trap-door access into the system if the operating system has problems
serious enough that it cannot be used. The trap-door mechanism provides enough access to the system
so that if it is necessary, you can format the flash file system, reinstall the operating system software
image by using the XMODEM Protocol, recover from a lost or forgotten password, and finally restart
the operating system. For more information, see the
section on page
You can disable password recovery. For more information, see the
