installation and configuration guide.
Cisco IOS Software Images
By default, your router ships with a Cisco IOS software image preloaded into the Flash memory card or
Flash disk inserted in PCMCIA slot 0 on the Route Processor (RP). Initially, your router is configured
to boot from this image. You can change this default and configure the router to boot from a Flash
memory card or Flash disk in slot 1 on the RP, or from a TFTP server. If you specify that the router boot
from an image on a TFTP server, you must verify that you have an Ethernet connection to the URL of
the TFTP server.
In addition, there is a mini-software image preloaded into the single inline memory module (SIMM) or
bootflash. This image can be used to boot the router if there is no other valid image available. It provides
a limited number of configuration commands that you can use to locate a valid Cisco IOS software image
or correct basic configuration problems. This image provides no routing capabilities.
Related issues are discussed in the following sections:
