Flash Memory
Flash memory allows you to remotely load and store multiple Cisco IOS software
and microcode images. You can download a new image over the network or from
a local server and then add the new image to Flash memory or replace the existing
files. You then can boot the routers either manually or automatically from any of
the stored images.
Flash memory also functions as a Trivial File Transfer Protocol (TFTP) server to
allow other servers to boot remotely from stored images or to copy them into their
own Flash memory. The onboard Flash memory (called bootflash) contains the
Cisco IOS boot image, and the Flash disk contains the Cisco IOS software image.
