This procedure is quite simple and the following is done on Linux. When you have an uncompressed IOS, you don’t need to wait for it when it comes to loading it on Dynamips.
unzip -p c3725-adventerprisek9-mz.124-25.bin > c3725-adventerprisek9-mz.124-25.image
You can see both compressed and uncompressed versions below.

Hi Nish, Could you show how to go back from image to bin?
Thanks
Add, I have tried the following method, but It doesn’t seem to work when I load the image on Dynamips… It does ZIP, but the MD5 checksum is different from the original BIN Image…
I am not sure how to go back to the original BIN image… If I find out, I will let you know.
Thanks a lot. I’ll post a solution if I find it.
