After installing new image, why router keeps 'decompressing'?

I found similar posts but they say this could be due to oversized images. It doesn't seem to be my case. My router memory count below shows I have 64D,16F as shown on the bottom of the pasted info below, isn't that correct ?

I downloaded an image from cisco.com for my C2610. I loaded the image onto the router via rommon/TFTP.

Then I noticed that every time I power cycle the C2610, I get the message "self decompressing....".

I made sure that the respective image I am trying to load, the 'c2600-j1s3-mz.123-16.bin' is supported by 64D and 16F routers. Note that is originally an image for 2610XM routers, however, before I downloaded an image for C2610 version 12.3 which also presented same problem.

Note that router was functional before I did this image download exercise.

Please advise what could be wrong and how I can get rid of this annoying 'decompressing' messages every time I start up router.

Re: After installing new image, why router keeps 'decompressing'

These are normal boot messages and there is no way to get rid of them , personally i would rather see them so then you know if you have a problem .

Re: After installing new image, why router keeps 'decompressing'

Hi,

you can unzip the image using gzip or any other ZIP program (on a MS PC rename it to *.zip). It contains the "real" binary, which is about 2-3 times larger. Never tried to boot directly, but in principle this should also work. Just be aware, that the unzipped IOS might not fit into flash anymore.

Hope this helps! Please rate all posts.

Regards, Martin

That isn't an issue.

"'c2600-j1s3-mz.123-16.bin'"

That Z in the file name means it is a zipped file. The router needs to decompress it into RAM (the M in the file name) to run it.

Re: After installing new image, why router keeps 'decompressing'

Thanks.

Just out of curiosity, if you don't mind, where can I get uncompressed images then ? I am searching http://tools.cisco.com and so far I've seen dozens of "Z" images which support the feature set I need (ISIS and Voice). I am wondering whether there is a specific location to get 'uncompressed' images ?
