flash crash

[Guest_imported]

I have a Cisco 2610 router and aftet it crashed, it started to boot as that:


System Bootstrap, Version 11.3(2)XA4, RELEASE SOFTWARE (fc1)
Copyright (c) 1999 by cisco Systems, Inc.
TAC:Home:SW:IOS:Specials for info
C2600 platform with 32768 Kbytes of main memory

device does not contain a valid magic number
boot: cannot open "flash:"
boot: cannot determine first file name on device "flash:"

rommon 1>


What do I have to do to repair this router? (Note: After router crashed, I rebooted it! )
If I must load its flash again, where can I find such program or file?

gravy,

as per my experience, you have no flash image, or yours has gone bad and it prob. won't boot again. Here's what you should do:

First, get a flash.bin image from Cisco.com or from someone's backup files. Do you have a Cisco login? Put this on a TFTP server and name it c2600.xxx-x.bin or whatever the corresponding name is. Open up this TFTP server for downloads.

then at the rommon> prompt do these things:

rommon 16 > IP_ADDRESS=171.68.171.0
rommon 17 > IP_SUBNET_MASK=255.255.254.0
rommon 18 > DEFAULT_GATEWAY=171.68.170.3
rommon 19 > TFTP_SERVER=171.69.1.157
rommon 20 > TFTP_FILE=c2600-is-mz.113-2.bin
rommon 21 > tftpdnld

obviously, change the numbers,names to fit your settings.

This should load your new flash image into flash. you can then type "boot flash:c2600-is-mz.113-2.bin" at the prompt to load new image.

One note, check the size of your flash image you download with the size of your flash memory and make sure you have room for the image.

If you want to make things really easy, hit one of your coleagues up for a flash chip with a good image already loaded and just swap chips . If you cant do this though, follow the instructions above.
