On a 2500 -- Before you begin, set the config register to 0x2101 to enable
write access to the flash memory(otherwise it is READ ONLY). The router will
reload into the 2500's boot-image to allow write access to flash..then you
can use the instructions below...

Installing the Router Software by Using the Console or Auxiliary Port
This section explains how to use the copy xmodem flash command to install
the router software from the CD-ROM onto the router.
----------------------------------------------------------------------------
---- Note The transfer takes place only on the port where you enter the command. If you download the software by using the console, all console output is discarded for the duration of the transfer. You can only download files to the router; you cannot copy files from the router. We recommend using the auxiliary port for this type of software download, because the auxiliary port has hardware flow control and full modem control. In addition, the transfer does not occupy the system console, so it is free for other uses. ---------------------------------------------------------------------------- ----The following example shows how to use the copy xmodem flash command on a Cisco 2500 series router:
Router# copy xmodem flash
**** WARNING ****
x/ymodem is a slow transfer protocol limited to the current speed
settings of the auxiliary/console ports. The use of the auxilary
port for this download is strongly recommended.
During the course of the download no exec input/output will be
available.
