Appendix B Using the ROM Monitor
Recovering Cisco IOS Software Images
Procedure for the xmodem Command
To copy the Cisco IOS software image from a console to CompactFlash memory, perform the following
steps:
Step 1 Connect the console using the instructions in the “Connecting to a Console Terminal or Modem” section
on page 3-22.
Step 2 Power up the router. The power-on self-test diagnostics run, and the boot ROM searches for a valid boot
image and Cisco IOS software image in CompactFlash memory. If the boot image and Cisco IOS
software image are not found, the ROM monitor prompt appears:
rommon 1>
Step 3 Enter the xmodem command and the name of the source file containing the Cisco IOS software image:
rommon 1> xmodem filename
Step 4 Messages similar to the following appear:
Do not start upload program yet...
File size Checksum File name
2537948 bytes (0x26b9dc) 3700-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 software image into CompactFlash 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 software image. Enter the ROM monitor reset
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” procedure on page B-6.
