Changing the Configuration Register Using Prompts
Entering confreg without an argument displays the contents of the virtual configuration register and a
prompt to alter the contents by describing the meaning of each bit.
In either case, the new virtual configuration register value is written into NVRAM but does not take
effect until you reset or reboot the router.
The following display shows an example of entering the confreg command:
rommon 7> confreg

Console Download
You can use console download, a ROM monitor function, to download over the router console port either
a software image or a configuration file. After download, the file is either saved to the mini-Flash
memory module or to main memory for execution (image files only).
Use console download when you do not have access to a Trivial File Transfer Protocol (TFTP) server.
Note If you want to download a software image or a configuration file to the router over the console port, you
must use the
ROM monitor command.
