IOS Trouble

[1CCNA]

I am having problems starting a router I get this error message:

---------------------------------------------------------------

System Bootstrap, Version 12.2(6r), RELEASE SOFTWARE (fc1)

PC = 0x0, Vector = 0x0, SP = 0x0

------------------------------------------------------------------

This error happens only when the IOS is greater than 7MB, When i put a smaller IOS the router starts just fine.

The Specs on the router are 2620 w/16MB Flash and 64MB RAM
IOS i'm trying to load:

c2600-ik9o3s3-mz.123-15b.bin (15MB)

The same IOS works on a different router with same specs, and i also try swaping the flash but still the same results.
Please Help!

You should post this one in the cisco:routers forums

anyway

regarding 12.3 releases have a read of this

basically the 12.3 releases require you to have an XM 2600, the one you are running is advanced security image. I have a couple of 2612's I run the 12.2T versions are the 12.3 versions wont decompress properly.

Its weird how you say it works on a different router with the same specs, are you sure this is exactly the same? it could also be as a result of how much of the DRAM is set asside as memory

for example when you see 59946K/4096K. some tweaking and you may be able to get it work,
