Procedures for Recovering Boot and System Images
If your Cisco 2600 series router experiences difficulties and no longer contains a valid
Cisco IOS software image in Flash memory, you can recover the Cisco IOS image using
one of the following ROM monitor commands:
• xmodem—Use this if the computer attached to your console has a terminal emulator
that has Xmodem capability.
• tftpdnld—Use this if you have a TFTP server directly connected to the Ethernet 0 port
or Token Ring 0 port.
Using the xmodem Command
The xmodem command establishes a connection between a console and the router console
port for disaster recoveryif both the boot and system images are erased from Flash memory.
xmodem [filename]—Establishes an Xmodem connection between the console and the
router. The optional parameter filename specifies the source file containing the Cisco IOS
image.
Other options include the following:
• c—Use cyclic redundancy check (CRC-16)
• y—Use Ymodem transfer protocol
• r—Copy the image to dynamic random-access memory (DRAM) for launch
• x—Do not launch image on completion of download
