When I boot up my 2600 I get a wierd message.
Here it is:

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 24576 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 > 

Then it just goes to rommon mode and I do not know what else to do. Do I need a new flash? I took some flash from a 2500 I had and I got the same message.

Your config register is pointing to the wrong location

This works for the 2500 series:

Boot you router while pressing CTRL and Break on the keyboard

at the prompt type o/r 0x2142 then return

              type i then return

              type n then return

              type enable then return

              type copy run start

              type configure terminal then return

              type config register 0x2102 then return

              type CTRL Z

              type copy run start

              type reload

If this does not work just log on to the cisco site and look up the config register value for the 2600 series and just subsistute the 0x2??? numbers

   If you have not programmed the router before reloading check that passwords are not set it is no good reloading the saved file if you do not know the password to access the router.

Good luck

Did you try to upgrade the flash?
>I took some flash from a 2500 I had and I got the same message.

The flash images from 2500 and 2600 are NOT compatible.

You need to download the correct IOS image for your router and copy it to flash. Easiest is with a TFTP server.
1. Get a tftp server (pumpkin at http://www.klever.net/kin/pumpkin.html) and install in on a PC
2. Get the appropriate flash image from another router or from Cisco and put the .bin file into your TFTP root directory.

3. from rommon 1 > tftpdnld
you should get an error message that says you need all these variables set, so use this example procedure to set them:
rommon 1 >IP_ADDRESS=123.45.67.8
rommon 2 >SUBNET_MASK=255.255.255.0
rommon 3 >DEFAULT_GATEWAY=123.45.67.1
rommon 4 >TFTP_SERVER=123.45.67.10
rommon 5 >FILE=c2600-i-mz-122.2-7.bin
rommon 6 >tftpdnld
Do you want to erase flash? Y
Continue? Y
Really? Y

Something like that, but it will be apparant with the first tftpdnld command.

dobbo,
I realize you are new to this forum and are only trying to help, but the protocol is to only post comments unless you are absolutely positive that you have the one and only solution to a question. In this case, your answer was clearly a wild guess which pre-maturely locked this question out of the general forum and other, more experienced, experts may miss the opportunity to help the questioner.

The site is more about collaboration between experts to
find the solution to a problem rather than an exam test site, most experts restrict themselves to providing
comments that the questioner can later select as the answer if it solves their problem and as such you
should only click on answer if you are 300% sure you have the solution. Sometimes you will provide helpful
comments for no reward, other times you may be rewarded points where others have helped without reward,
it evens itself out.

Comments
Comments are intended to be used as a collaboration tool. Many Experts choose to post their solutions

as comments only.

Answers
An answer is a specific solution to a question and should be submitted if it will solve the questioner's

problem and doesn't duplicate a previous comment.

Comment Vs. Answer
If you are unsure of your solution, post it as a comment. Members can accept comments as solutions and

award you Expert Points for them.

OK, I put a new flash into the 2600 and I did a tftpdnld in rommon mode, and I do not see the magic number message anymore, But now I am getting a different message after the router decompresses the image.
here is the message:

Unexpected exception to CPU vector 1200, PC = 80323AC4
-Traceback= 80323AC4 80323C10 8025F354 80345F10 80347B84 802F5430 802F54E0 80250C44 80250EB8 802FF6CC

PC = 0x80323ac4, Vector = 0x1200, SP = 0x814a0328

I read on the cisco site that a new IOS should take care of the SegV , but it does not look like it helped any since I just placed a new IOS on it

Did you look carefully at the requirements for that particular image of the IOS? Do you have the required amount of FLASH and DRAM? Which exact image are you trying to load?
