Appendix B Using the ROM Monitor

Recovering Cisco IOS Software Images

Procedure for the xmodem Command

To copy a Cisco IOS image from a console to Flash memory, perform the following procedure.

Note File transfer from a console is slow and will take many minutes.

Step 1 Connect the console using the instructions in the “Connecting to a Console Terminal or Modem” section on page 3-43.

Step 2 Power on the router. The power-on self-test diagnostics run and the boot ROM searches for a valid boot image and Cisco IOS image in Flash memory. If the boot image and Cisco IOS image are not found, the ROM monitor prompt is displayed:

rommon 1>

Step 3 Enter the xmodem command and the name of the source file containing the Cisco IOS image:

rommon 1> xmodem filename

Step 4 The source file is searched for and found. Messages similar to the following appear:

Do not start upload program yet...

File size	Checksum	File name
2537948 bytes	(0x26b9dc)	3640-boot-l

WARN: This operation will ERASE bootflash. If the xmodem download to bootflash fails, you will lose any good image you may already have in bootflash.

Invoke this application only for disaster recovery.

Do you wish to continue? [yes/no]:

Step 5 Enter yes to copy the Cisco IOS image into Flash memory. Messages similar to the following appear:

Ready to receive file prog ...

Erasing flash at 0x3000000

program flash location 0x3000000

Transfer complete!

The router is now ready to boot from the Cisco IOS image. Enter the reset ROM monitor command to reboot the router.

Note If you have set the console speed to 115200, you may wish to reset it to the previous speed or to the factory default speed (typically 9600 bps). See the “Configuration Register Commands” procedure on page B-7.
