I am currently using c2500-jos56i-l.120-14.bin(10.6 meg ent/fw/ipsec) on my
routers (8 Flash/16 DRAM) I performed all the bootcamp labs never crashed
the routers once, I did have problems with later versions however (12.1)
Size was the same, it just wasn't stable. Go figure, I used the TFTP server
to load it up (compress worked also, but its to slow)

I second that. I had nothing but crashes trying to uncompress an Enterprise
image on a 16 mb 2500. Just guessing, I'd say that you've got to leave
probably 25% of the memory free to have it load. Can anyone verify that?

Just remember that you are uncompressing the image into ram, and then
attempting to run it from there. If the image is 15MB in size, you can most
likely compress it down to just under 8MB's. As soon as it loads though it
most likely will crash the router, since max ram in a 2500 is 16MB and you
have just taken up 15 of that. Even worse most 2500's set aside 2 MB's as
buffer leaving 14MB to start with.
Believe me when I tell you, it will crash the router. I use images that are
10MB requiring 6MB of Ram. When you start doing tricky stuff they some times
start having MALLOC and TRACEBACK errors, or worse lock up tight. 11.3
enterprise is about as far as you can go doing this.
The same applies to TFTP'ing the image as well.
