Appendix B Using the ROM Monitor

Recovering Cisco IOS Software Images

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

rommon 1> xmodem filename

When the source file is found, messages similar to the following appear:

Do not start upload program yet...

File size	Checksum	File name
2537948 bytes	(0x26b9dc)	c2600-i-mz.122-10.bin

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 4 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 want 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.

Copying an Image from a TFTP Server Using the tftpdnld Command

The tftpdnld command downloads a Cisco IOS software image from a remote server accessible from a FastEthernet, Ethernet, or Token Ring network interface on a Cisco 2600 series router (except Cisco 2691). The tftpdnld command downloads the Cisco IOS software image into flash memory using TFTP.

Restrictions on the tftpdnld Command

The following software restrictions apply when using the tftpdnld command:

•Ethernet and FastEthernet—Accepts and sends only Ethernet V2.0 data packets.

•Token Ring—Accepts and sends only Token Ring frames with IEEE802.3 SNAP frames. Does not support any frames with routing information fields (RIFs), limiting all use of the tftpdnld command to a TFTP server on the local ring. If the TFTP server resides off the local ring, you must establish a path to the server through a router or transparent bridge from the local ring.
